The Melbourne mop-up. What needs to happen next?
While the number of new coronavirus cases in Melbourne continues to fall, for many it's not falling fast enough. The average number of daily cases is edging down day by day, but there's a long way to go until it meets the hurdle to take the big step out of lockdown. So why are cases falling so slowly and what needs to happen next to get cases down? On today's show: * As numbers drop why don't we see a faster fall in the tail? * How long can a person be asymptomatic? Does it just disappear? Can they become asymptomatic again? * My husband and I are chronic asthmatics and take a preventer. Would good asthma management assist us if we caught COVID-19? * Would there have been less antibiotic use this year and how beneficial might that be? And it's Quick Fire Friday: * What episode number are we up to? * Is Norman's towel ready and waiting? * Is there more chance of catching coronavirus from getting on a plane or sitting inside for a meeting/lecture? Or are they the same? * Do you have any thoughts as to what the minimum age for vaccination might be? * What's the risk of spread of coronavirus on children's play equipment?

The ambitious mass testing plan that might be as good as a vaccine
The longer this pandemic drags on, the more likely it is that people will get fed up with taking themselves off for a coronavirus test every time they get sick. It might sound counterintuitive, but the solution might be to test everyone more. Regular, targeted but rapid testing of people, regardless of whether they have symptoms or not, could allow us all to return to a somewhat normal life. On today's Coronacast, Tegan Taylor and Dr Norman Swan discuss the possibilities and challenges of a mass testing scheme. Also today: * Will kids fail to build up a strong immune system since they've avoided so many colds and flus this year? * What are some of the longer term effects of coronavirus on the body?

Why is coronavirus not killing as many people?
For the first time in two months, Australia has finally recorded a day with no deaths from coronavirus. It's a huge milestone after Victoria's second wave pushed Australia's national COVID-19 death toll to more than 800. While Australia's second wave is coming to an end, in Europe case numbers are again increasing. But unlike last time, the death rate doesn't seem to be going up with the number of cases. On today's show: * Why are the number of cases increasing overseas, but the death rate is not? * When will the Oxford vaccine complete stage 3 trials (if it's successful)? And Norman and Tegan talk about an interesting pre-print study that has found the number of COVID-19 infections in Australia could be much higher than previously thought.

How coronavirus is hiding a future cancer wave
The immediate and long term health effects of COVID-19 have been well reported over the past several months, but it may have crowded out other illnesses and diseases. According to the Federal Government's national cancer agency Cancer Australia, treatments and tests for the most common types of cancer have plummeted since the pandemic began. It's raised concerns that because people might have been unable or avoided going to the doctor during lockdown, they could be living with undiagnosed and untreated cancer. On today's show: * What's happened to cancer diagnosis over the past six months? * How did Norman get sick again? What's he been doing? Has he been washing his hands? * You've mentioned that the coronavirus is mutating. Can you tell me more about that?

Why the secrecy around the Oxford coronavirus vaccine trial?
The Oxford coronavirus vaccine trial is set to resume after it was abruptly halted when a participant experienced some sort of medical event. All we know is that the woman was given the potential vaccine and the event was serious enough to hit pause on the trial last week. The company developing the potential vaccine says it cannot disclose further medical information. But given the global interest in the trial and what'll be asked of everyone if it is approved, should we be given more information as to what might have happened? On today's show: * Why is Victoria's death rate still so high, even though infections are dropping off? * Some shops are marketing anti-viral fabrics in their masks. Is that a real thing? * The 2009 H1N1 vaccine was ready in six months. Could that be the case for coronavirus in the future?

The crazy theory that masks are building up our coronavirus immunity
Wearing a mask is one of the simplest and most effective ways you can reduce your chances of catching or spreading coronavirus when you're around other people. But a new theory suggests the fabric over your face also might be providing a crude form of immunisation against the disease. The idea is that masks might be allowing a very small amount of the virus to slip through into the airways – not enough to get sick, but just enough to build up some immunity. On today's show: * Masks, COVID-19 and immunity. Could they be linked? * A new survey on Australians attitudes to mandatory masks * The latest news from the (currently halted) Oxford vaccine trial * Quick fire Friday (with music this time!)

The Oxford vaccine's troubles. Why it's not doomed (yet)
The vaccine widely considered our best shot at bringing this pandemic to an end has run into a bit of trouble, after a trial participant suffered a medical problem. Because safety is incredibly important, trials of the Oxford University's potential coronavirus vaccine have been put on hold until scientists can work out what went wrong. It could be nothing, or it could be the end of this vaccine. At the moment, all we can do is wait. But it's important to remember pausing vaccine trials is common. So what might have gone wrong and where we could end up?

Will contact tracers finally bust Victoria's clusters?
Victoria's daily coronavirus tally is finally starting to drop, but the roadmap out of lockdown suggests state officials don't believe they'll be back down in single digits until November. The cause for the delay appears to be Victoria's contact tracing system, which the Prime Minister claims is years behind New South Wales. So will the newly announced changes to Victoria's contact tracing system finally bring things back under control so the state can open up faster? On today's show: * What makes a good contact tracing system? * Why aren't all states and territories using the same contact tracing system? And we've got some really interesting replies from healthcare workers about how well they're being protected against the COVID-19 virus.

The problem with coronavirus in hospitals isn't just a Victorian one
Over the past few days, a number of worrying COVID-19 infections have popped up in hospitals in Queensland and New South Wales. While the problem with infections in the healthcare sector in Victoria is well known, hospital outbreaks in other states are a warning sign that things aren't quite right. So are hospitals in Victoria any more susceptible to coronavirus outbreaks, or is it potentially a problem across the country? On today's show: * Are coronavirus infection problems specific to Victoria? * How much time does Norman Swan spend researching coronavirus? * And we’ve had loads of questions about the rising number of daily cases in Europe. Why are cases going up now? Why isn’t the death rate going up as much as during the first wave?

What to make of Victoria's roadmap out of lockdown
Melburnians will face another fortnight of lockdown after September 13, but the Victorian Premier has also announced a plan for the eventual reopening of the state. There will be a few small changes after stage 4 restrictions were originally going to end, like an extra hour before curfew and social "bubbles" for those living on their own. But Victorians are being warned the trip out of lockdown will take a long time. So why wasn't the original six weeks enough? On today's show: * Why wasn't six weeks enough for stage 4 lockdowns? * What's going on in Queensland with the government furloughing hundreds of healthcare workers after a single staff member tested positive? * What does a COVID-19 vaccine entail? Does it mean that you can get it without becoming sick? * Will a vaccine stop other health complications that sometimes come from COVID-19?

Why Christmas could be a super-spreading event
No matter what else happens this year, Christmas 2020 is probably going to be like no other you've experienced. You might opt to just celebrate quietly at home to avoid a potential outbreak, but some may decide to proceed with a big family gathering. So how risky might Christmas be and could it be a massive super-spreading event? On today's show: * What's going on in Airlie Beach with SARS-CoV-2 being discovered in sewage? * Should I be worried? * How do we hold mass events over summer without a coronavirus disaster? * Should masks be mandated now so we can all enjoy a semi-normal Christmas? And Olivia Willis from Patient Zero drops by to talk about the hunt for the very first person to contract coronavirus.

Should you get pregnant in the COVID era?
There is still so much to learn about the novel coronavirus, but scientists have unlocked some clues about the way COVID-19 affects pregnant women and their unborn children. A review of dozens of scientific studies has found that women who contract coronavirus during pregnancy may have a higher risk of premature delivery. And while pregnant women also seem to have less severe symptoms initially, if they do get sick it's likely to be worse than non-pregnant patients. Also on the show: * Everyone has an opinion about mandatory isolation for positive cases! * Can you tell if you've got COVID-19 by monitoring your resting heart rate? * What percentage of people would need to be vaccinated to lift restrictions?

Is it time to make people who test positive quarantine in special clinics?
Australia was one of the first countries to require returning overseas travellers to isolate in hotel rooms, which has significantly helped keep community transmission of coronavirus down. But if someone already in Australia tests positive, they're allowed to isolate at home, which risks infection to family or the wider community So why isn't Australia following China's lead and making it mandatory for people with coronavirus to isolate in special clinics or hotels? On today's show: * Could COVID-19 positive clinics help bring Australia's coronavirus count down? * How would you manage families or children? And we return to a segment where we look into how other countries are going. Today we focus on Spain, which is seeing a large resurgence of the virus. What can we learn from what's happening in Europe?

What could Victoria's path out of lockdown look like?
With the number of new coronavirus infections falling to double digits, Victoria's Premier Daniel Andrews says he will reveal the state's roadmap out of lockdown this weekend. Stage 4 restrictions are due to end on September 13, and many Victorians are wondering what happens past that date. There are many ways the state could approach its return to a more normal existence. So what are some possible benchmarks to reach before they can even consider opening again? On today's show: * What is the pathway out of lockdown for Victoria? * What could stages of normality look like? * What can we learn from how New Zealand got out of stage 4? * How should we define what a hotspot is? * Can a person have two vaccines to get better coverage?

Are gyms the weakest link in NSW?
Sydney's CBD coronavirus cluster has grown over the weekend, with more people being diagnosed with COVID-19 and being linked back to a city fitness centre. A health notice was issued on Saturday for people who attended the Tattersall's fitness centre at certain times over five days in middle to late August. There are also alerts for other gyms in the city, after an infected person visited them last week. So are gyms becoming coronavirus hotspots and are they any riskier than other indoor environments? On today's show: * Is there something that causes gyms to be a riskier venue than other places? * So should I avoid the gym and just stay home and watch TV? * What about runners or people exercising outdoors? * What can gyms tell us about how coronavirus spreads? * What's happening with the healthcare worker numbers in Victoria? * What's going on with China's authorisation of a vaccine for emergency use? * Have there been any studies into the effect of climate or weather and CO…

How many cases a day are we happy to live with?
As the number of new coronavirus cases in Victoria continue to fall, conversations are turning to coming out of stage 4 restrictions. Part of that discussion is how many new cases will be accepted each day before restrictions can be eased. NSW has been ticking along with a handful of daily cases, and so far seems to have been able to manage it without a massive outbreak. So what can we manage day to day? And what can be tolerated? On today's show: * What level of virus would we be able to tolerate long term? * Is zero community spread a long-term goal? * How is it going in NSW and Queensland at the moment? * Can Norman please say something nicer about Victoria? Is there any silver lining yet? * What can Victorians do at an individual level to help get cases down? And it's time for quick fire Friday: * My kids are using an iPad for hours a day in lockdown. What's the impact on their mental health or their eyes? * If the cold is often caused by coronaviruses, could any vaccin…

Are Victoria's numbers really going down as much as we think?
While the decline in Victoria's coronavirus case numbers has been incredibly positive over the past few weeks, worryingly the number of people getting tested is also falling. Yesterday, Victoria recorded fewer than 14,000 tests — much lower than NSW's 25,000 and even Queensland's 20,000 tests. So could a lower testing rate be hiding the true situation in Victoria and are Victoria's numbers really going down as much as we think? On today's show: * How do we know what the true number of cases in Victoria are if there's not enough testing? * Are the right people being tested? * Why might people not be coming forward to get tested? * Did the man in Hong Kong who tested positive for COVID-19 twice really have it the first time? * What's the difference between the Oxford vaccine and University of Queensland vaccine? * Why are scientists trying to make different types of vaccines when the Oxford vaccine might work?

The top 3 healthcare jobs most at risk of coronavirus
The Victorian Government has finally released information that provides a much deeper insight into how many healthcare workers have been infected with coronavirus in hospitals and aged care facilities. It says that "70 to 80 per cent" of healthcare workers who were infected with COVID-19 caught it at work, which is up from its previous estimate of 10 to 15 per cent. But yet to be published research has found that some jobs are far riskier than others and the risk of contracting the virus depends where in the system you work. So which jobs are most at risk? On today's show: * What have we learnt from the Victorian Government's information on healthcare worker statistics? * Which jobs are most at risk? * Why are foetal cells and abortions being talked about in relation to the Oxford coronavirus vaccine? * A Hong Kong man has been reinfected with coronavirus. What use is a vaccine if you can get coronavirus again?

What lessons have NSW and Queensland learned from Victoria?
Queensland health authorities say they're worried by the growing number of coronavirus cases in the state, and are recommending people wear facemasks. In NSW, authorities say the virus is lurking in parts of Sydney and are urging people to get tested. Both states have so far kept cases low, no doubt looking south to Victoria for an example as to what happens if it gets out of control. So what other lessons have NSW and Queensland learnt from Victoria? On today's show: * Can you please, please, please talk a bit about NSW? Case numbers are rising, restrictions are being added and I feel lost and confused. * You have said many times that Victoria isn't being transparent. Can you explain why you say that? * Can you clarify if the vaccines that are being developed are live vaccines? And Norman has some news about the way the Oxford vaccine (assuming it's proven safe and effective) will have to be transported, and why it's so different from other vaccines.

Can Victoria get it done in three more weeks?
Melbourne is now halfway through its stage 4 lockdown, and if the daily case numbers are anything to go by, the restrictions are clearly working. At the start of the month, Victoria recorded more than 700 cases in a single day. Daily cases are now down to the low 200s. But is three more weeks of hard lockdown enough to get the number to where it needs to be? And what else could be standing in the way of the city coming out of stage 4? On today's show: * Is three more weeks enough to get Melbourne's numbers down? * What about by Christmas? We have a few updates and clarifications regarding testing times and the story about which COVID-19 symptoms come first (on average). If that's not enough, we also have a quick fire round on vaccines! * How is an unvaccinated person a threat to a vaccinated person? * How will the vaccine be distributed? * Is there enough evidence to suggest that it is safe? * Will it be safe for pregnant women? * Who will be getting the vaccine first?

Could aged care and hospitals keep Victoria locked up?
New coronavirus cases in Victoria have been falling nicely this week, but if you look a little closer there are still some concerning numbers. A large number of healthcare workers are still being infected. And cases from aged care still appear to be making up large parts of the daily totals. So could the Government's struggle to rein in infections in aged care and hospitals be holding Victoria back? On today's show: * Is the drop in Victorian case numbers due to lower testing? * But didn't the Victorian Health Minister say only 10-15 percent of health workers are catching it at work? * What are the chances that aged care and hospital transmissions will keep Victoria in lockdown? * Can you tell me more about the Oxford vaccine? How does it work? * Will the vaccine work for people with weak immune systems? * Would Norman and Tegan personally take it? And we put the call out yesterday to see how long coronavirus tests are taking around the country. We've had a huge response, so…

Why make a vaccine mandatory?
When Prime Minister Scott Morrison said he'd like to see any COVID vaccination be as "as mandatory as you can possibly make it", he put the idea of compulsory vaccines on the table. Yesterday he announced the Government had signed a "letter of intent" with a British pharmaceutical giant for access to a coronavirus vaccine if it is successful in clinical trials. So assuming the vaccine is proven to be safe and effective, what are some scientific reasons behind a mandatory rollout of mass vaccination? On today's show: * Are there any scientific reasons for mandatory vaccination? * What are the ethics of mandatory vaccination? * Are there any ways to speed up getting test results back? And Norman has some research about COVID symptoms and what, on average, comes first, second, third and fourth, and why it shows testing regimes should be expanded.

Are hotels the best way of managing quarantine?
Governments in Australia and New Zealand are scrambling to find out more about recent coronavirus cases that appear to have escaped from hotel quarantine. NSW Health is looking into how a security guard became infected with coronavirus while working at a hotel quarantine facility in early August. And in New Zealand, a maintenance worker at a hotel managed isolation facility has been infected by a returned traveller from the USA, but no obvious person-to-person connection has been identified. And don't forget the huge problems in Victoria. So it raises the question: are hotels the best way of managing COVID quarantine? On today's show: * With new possible hotel quarantine breaches in NSW and New Zealand, are hotels the best way to manage quarantine? * Isn't it inevitable that when humans are close together, the virus will find a way eventually? * Why are we still talking about superspreaders when we should be talking about superspreading environments? * Why are we still talking…

Will Australia have access to a vaccine if/when it is discovered?
While scientists are yet to come through with a proven coronavirus vaccine, it hasn't stopped governments around the world signing up for some of the most promising candidates. The Australian Government is reportedly in "advanced negotiations" with a range of different companies and close to a deal that would allow production in Australia. But what happens if the deals are for vaccines that end up not working? And is Australia at risk of missing out? On today's show: * Will Australia have access to a vaccine if/when it is discovered? * What happens to production of vaccines if they are shown not to work? * Can the outbreak in New Zealand be traced back to hotel quarantine? What about Victoria? * How's the are of the virus coming in via cold storage looking?

Did coronavirus slip into NZ by cold freight?
As the coronavirus outbreak in New Zealand continues to grow, theories are circulating about how the virus snuck back into the country. While the most likely explanation is it came in via a human, there are a few other suggestions. One is that it never left and has been circulating silently for months, though health authorities say that this is unlikely. Another is that it slipped back into the country on imported cold meats. So how likely is it? On today's show: * Are the numbers in Victoria getting better? Are health workers still a concern? * How did coronavirus make it back into New Zealand? * Has SARS-CoV-2 mutated so that it's now more contagious? And Norman and Tegan discuss a fascinating pre-print study about a fishing trip where nearly everyone on board got infected, except three people. What could that mean for vaccine development?

NZ's cases grow. What's the point of going for elimination?
The number of coronavirus cases in New Zealand has continued to grow, as health authorities desperately try to track down and stop the outbreak. Prior to the coronavirus being found in the community, New Zealand had more than 100 days of zero community transmission. But as they've just found out, keeping it that way seems impossible. So if the virus is going to make it into your community eventually, what's the point of trying to eliminate spread? On today's show: * Victoria's numbers are falling nicely now. Is zero cases still something to aim for? * New Zealand's cases of community transmission are on the rise again. What does it teach us about trying to eliminate the COVID-19 virus? * We've had a lot of questions about a possible treatment for COVID-19, with a mix of the drugs ivermectin and doxycycline (also zinc). Why are some people suggesting it should be studied? It's also time for another Quick Fire Friday!

Is the Russian vaccine dodgy, a game changer, or both?
Russia's announcement that its new coronavirus vaccine has been approved and is ready to be rolled out has been attacked by vaccine experts, describing it as reckless. No reliable evidence has so far been released to show that it is effective. And more dangerously, no large scale safety trial has been completed. So what now for the Russian coronavirus vaccine? And what could it mean for the rest of the world's efforts? On today's show: * Could Russia's vaccine actually be effective? * If it is effective, what is the problem then? * What are coronavirus vaccines actually attempting to do? Stop the infection or just stop the disease? * Victoria's numbers are up again. What's the latest? * And what on earth is happening in New Zealand?

As Melbourne recovers, regional Victoria is struggling
The stage 4 lockdown in Melbourne has been successful so far in pushing down the number of cases in metro areas, but regional Victoria risks being left behind. While the number of cases in regional areas are far smaller, centres like Bendigo and Geelong are struggling to get things under control. So is there a possibility that Melbourne will get on top of things but regional Victoria will still have problems? On today's show: * Are cases increasing in regional Victoria and what could happen if they don’t start falling? * Do some regional areas need stronger restrictions? * On healthcare workers, how do we stop them getting sick? * What about negative pressure rooms in hospitals? * In NSW, clusters seem to be getting bigger, especially around schools. Weren’t they supposed to be lower risk? * Should NSW go into tighter lockdown? * Everyone is making sock masks. Aren’t they going to be too leaky?

When will Victoria's death count stop rising?
The tragic reality of so many people being infected with coronavirus over the past month has started to play out in Victoria. Yesterday a record number of Victorians died of coronavirus in a single day. So while the number of daily cases seems to have started to fall, when will the death rate also start to go down? On today's show: * It seems that while new daily cases have started to fall, sadly the death rate is up. Why are we only seeing it now? * NSW says it's halfway through its critical phase. What does that mean? * How did New Zealand get to zero spread? * Does Australia still have a chance to get there? * How are vaccines distributed in pandemics? Who gets it first? And Norman has a correction and clarification from comments in a previous episode about swine flu and Victoria.

Can we do better at protecting health care workers?
One of the startling figures from the Victorian coronavirus wave is the number of healthcare workers who are getting sick. Nearly 1000 Victorian healthcare workers currently have COVID-19, a number that has doubled in less than a fortnight. When coronavirus hit China and Italy, we saw terrible numbers of healthcare workers getting really sick and sometimes dying. So as the numbers continue to rise, what could happen in Victoria? On today's show: * How many healthcare workers could die? * Norman talks about a study that looks at antibodies in health care workers in New York, which also reports some encouraging information about the accuracy of coronavirus tests. * Numbers are slightly down in Victoria over the weekend. Is Norman going to do a victory lap about his prediction? * Physiotherapists and other allied health professionals must now wear eye protection. This even applies in clinics treating only non-symptomatic people, with everybody wearing masks. I don't understand thi…

What happens next in Victoria depends on its mystery cases
Norman Swan made a big call in predicting that Victoria will start to see a reduction in coronavirus cases by next week, but not everyone agrees with him. Some health experts say it's more likely that the state will experience a wide curve, rather than a sharp decline. Ultimately, it'll come down to how many unknown mystery cases there are in the community. So is Norman sticking by his prediction? On today's show: * How sure is Norman about his big prediction? * What did we learn from SARS-CoV-1? Can we apply any knowledge from that? * Can you get COVID-19 multiple times within a short time frame? * If I can smell cigarette smoke and if I inhaled it from someone who was infected could I get sick? * What is "pool testing"? Why don't we use it in Australia? * Does UVC light effectively kill airborne coronavirus?

When will stage 4 restrictions start to shift the needle?
There's been another grim round of record-breaking coronavirus numbers in Victoria: the highest daily tally, the highest death toll and Australia's youngest victim – a man in his 30s. It's now been almost a month since the state was placed into stage 3 lockdown, and a few days since they were ratcheted up to stage 4. Today on Coronacast, some predictions on when numbers will finally start falling. Also on the show: * What happens with lockdowns if a vaccine never arrives? * What's the success rate on most vaccines?
Aug 4, 2020
Have we been too easy on rule breakers?
The Victorian Premier Daniel Andrews has announced that all COVID positive cases will be doorknocked multiple times, as authorities continue to tighten restrictions in Melbourne. Complying with rules to isolate and quarantine has been a major problem in Victoria. Recent figures show as many as one in four people who were supposed to be isolating at home, were not. So why has it taken this long to crack down on rule breakers? Or is the punitive approach more harmful in the long term? On today's show: * How do you stop people from breaking the rules? * What do you do about people who continue to refuse to follow the rules? * The head of the World Health Organisation says there might not be a COVID silver bullet. How long could this all go on? * What's the point of Melbourne's curfew? * Is the cooler weather in Melbourne playing a part in the sudden rise in cases? * Is there any point checking people's temperatures? Or is it a waste of time? * I have hay fever and a constant ru…

Why stage 3 lockdowns were successful, but not quite enough
More than 250,000 workers in Melbourne will be forced to stay home to try and stop the spread of coronavirus. Yesterday, Victorian Premier Daniel Andrews ordered the closure of thousands of shops, factories and offices in an attempt to not only flatten the curve but force it downwards. So as the Victorian Government ratchets down restrictions even further, you'd be forgiven for thinking 'what was the point of stage 3?' So today, why stage 3 lockdowns were successful, but not quite enough. On today's show: * What's the point of the new restrictions that are closing businesses across Melbourne? * Were stage 3 restrictions a failure? * Other parts of the country are increasing restrictions too. Are they a bit spooked? * Are children really not that infectious? New research seems to challenge that idea and finds they are actually carrying a lot of virus. * What's going on with rapid testing? The UK are rolling out tests that give results in 90 minutes. Can we have these in Austral…

Melbourne's lockdown pain. How do we make it worth it?
Melbourne has spent its first night under curfew, imposed to try and halt the spread of coronavirus. Yesterday, Victorian Premier Daniel Andrews announced Melbourne would move to stage 4 restrictions for six weeks. Reasons to leave your house, education, ceremonies, travel and the number of people allowed to gather have all been tightened. It's going to be a tough month and half, so how do we make sure it's all worth it? On today's show: * How do we make sure these stage 4 restrictions are worth it? * What should we hope for when we come out the other side? * When will it all end? By Christmas? * I'm in Queensland and want to wear a mask when I go out but have a one year old. I would feel terrible protecting myself while leaving her exposed. Would wearing a mask offer us both any protection?

Another record :( Melbourne’s case number rollercoaster
Australia has smashed its daily coronavirus record, with Victoria recording around 700 new infections yesterday. The state's second surge has been a rollercoaster ride of new peaks and falls – but what's concerning everyone is that the overall trend for Victoria is still on the rise. On today's Coronacast, Norman Swan tells Tegan Taylor where he thinks all of this could be heading for Victoria, as well as surrounding states. Also on today: * Another record day in Victoria. It's been a rollercoaster of cases, and emotions. * Why is Victoria waiting until Monday to impose mandatory masks statewide? * How do we combat community coronavirus fatigue? * Regarding the episode about COVID-toes, it's likely describing chilblains.

Is Queensland overreacting by banning Sydneysiders?
The daily coronavirus tallies in Queensland and New South Wales are nowhere near as high as Victoria, but health experts are warning that both states are now on a knife's edge From early Saturday morning, Queensland will block all Sydneysiders from crossing its border, declaring the whole city a hotspot. The New South Wales Government is so far still resisting any talk of another lockdown. So is banning Sydneysiders fair enough? Or an overreaction? On today's show: * Is Queensland overreacting by banning Sydneysiders? * Why does Queensland have concerns about Sydney? * Why aren't other countries that are coming out of lockdown experiencing outbreaks? * Do I have COVID toes and should I get a test? And Coronacast looks at a new study that examines whether a 14-day quarantine is really long enough for coronavirus.

Coronavirus or terrifying hallucinations? Aged care's stark choice
When it comes to coronavirus, there is probably no one more vulnerable to the disease than an elderly resident at an aged care facility. With 769 active cases relating to outbreaks in more than 60 Victorian aged care homes, you may think the solution could be evacuating those residents and putting them in hospital until the worst is over. But on today's Coronacast, Norman Swan tells Tegan Taylor that while a change of location might protect an elderly resident from COVID-19, it could put them at risk of a terrifying medical condition known as delirium. Also on the show: * Norman has previously said that coronavirus can survive for days on some surfaces. So why shouldn't I worry about groceries? * How should I clean the gym and do anti-bacterial wipes kill the virus?

Here's why Victoria's spike isn't going down just yet
When you think of a coronavirus outbreak on a graph, you probably imagine a big peak and then a swift downward curve as lockdown measures bring the number of infections under control. But Victoria's recent spike looks pretty different. A record-breaking daily tally is followed by a fall in cases before infections suddenly rise again. And also, why has this happened in Victoria? Is it just unlucky or could there be more to it? Health reporter Tegan Taylor has been speaking to some epidemiologists about Victoria's unusual spike and fills in Norman Swan on what they think is going on here. On today's show: * Another day, another massive amount of cases in Victoria. Why isn't it going down? * Why is it different from the first time we were in lockdown? * If coronavirus is on playground equipment, will the rain wash it off? * Do we really need to wash the groceries? It takes one hour to buy them and another two hours to wash and dry them. * Since March, people have been arguing tha…

Coronavirus is not just an old person's virus
We often hear that coronavirus doesn't discriminate when it comes to age, but after infection it does tend to get deadlier as patients get older. So while COVID-19 does kill more elderly people, youth is not a guarantee that you'll sail through with mild symptoms and no problems. Over the weekend, Victorian Premier Daniel Andrews reminded Victorians that currently two children and eight people under the age of 30 were in hospital with COVID-19. So why are the numbers of young people in hospital growing? On today's show: * How many younger patients are currently in hospital in Victoria? * If you get the virus as a younger person, what long-term damage might there be? * As some of the candidate vaccines go into phase 3 trials, aren't there ethical issues by giving people a placebo and not the vaccine? * Norman has said the key to coronavirus in WA is testing, so what symptoms should be the trigger to get tested? And Norman has some research from the journal Science about undocum…

Is a six-week lockdown going to be enough?
A month ago, consecutive days of more than 400 new coronavirus cases would have been almost unbelievable. Sadly, it's become a reality for Victoria. Melbourne has now been in lockdown for a fortnight, desperately trying to get the numbers to fall. The lockdown was originally imposed for six weeks, but with four weeks to go and the number of cases remaining stubbornly high, is another month going to be enough? On today's show: * Is six weeks going to be enough for Melbourne? * When do we know if it's safe to reopen again? * Could the virus be circulating in Queensland? What should people there be doing? * I'm a garden labourer working in Melbourne. My mask is causing my safety glasses to fog up. How do I stop this happening? * Should people trim their beard to give masks a more secure fit? * Some people have told me that surface transfer is not an issue anymore. Could you please outline the current understanding of how coronavirus spreads?

Why are thousands of people not complying with the rules?
The Victorian Premier Daniel Andrews revealed some startling figures yesterday. It wasn't just that the state recorded its highest number of new coronavirus cases in a single day, it was the huge percentage of people that were getting tested and not isolating before they got their result. And in Queensland, there's another issue where people are skipping quarantine before their time is up. So what problems is this all causing? On today's show: * Why are people not complying with the quarantine and isolation rules? * Many of Victoria's outbreaks are in essential industries. How can we control that? * How long is an asymptomatic person contagious for? 14 days? Or forever? How does it work? * There has been a lot of talk about different ways of cleaning masks. Isn't detergent and water just as good as anything? And if you want a back to basics on how to put on a mask, check out our Instagram account @abchealth for a how-to by Dr Norman Swan.

Melbourne's 2nd worst day. Are lockdowns working?
Melbourne recorded its second worst day yesterday with 374 new cases of coronavirus. It's also been nearly two weeks since the city-wide lockdown was reimposed, but as yet there has been no reduction in new cases and it's unclear whether the curve is flattening. Restrictions seemed to work a lot faster the first time, so what’s going on? And you asked for it: we have Norman's explanation and breakdown of the promising results of the Oxford University coronavirus vaccine. On today's show: * Shouldn't we be seeing a reduction in new Melbourne cases by now? * Is it time to impose tighter restrictions? * Why are we not being advised to soak reusable face masks in ethanol? * I'm a mask newbie. I experienced a suffocating feeling, like I was in a stuffy room with humid stale air. Do you have any advice? And you have some comments about not inhaling scotchgard, questions about if we're anti-Queensland because we forgot to mention them yesterday and was Norman grumpy on Monday. Als…

What state is most primed for a coronavirus outbreak?
While coronavirus case numbers were up in NSW yesterday, health authorities said that they could identify where every infection came from. Being able to trace every case is a great sign that outbreaks are being brought back under control. So is NSW out of the woods? And while NSW might be starting to get back on top of things, research has shown that what’s happening in NSW and Victoria could happen anywhere. On today's show: * Norman explains some intriguing figures about which Australian states are most primed for a coronavirus outbreak. And loads more questions have come in on masks: * Can I lightly scotchgard the outer layer of fabric? * Is scotchgard toxic to breathe through? * Can you wear a face shield instead of a mask? * I am hearing mixed reports about how often to wash a mask. Can you please clarify the best practice? * Can I hot wash and reuse the blue disposable masks?
Jul 19, 2020
Why aren't Melbourne's coronavirus numbers coming down?
The Victorian Government has imposed new restrictions on Melbourne, mandating the use of masks. Following an increase in coronavirus cases over the last few days, people living in metropolitan Melbourne and Mitchell Shire will be required to wear a face covering when leaving home for one of the four allowed reasons. Residents have now been under restrictions for more than a week, so why aren't Melbourne's coronavirus numbers coming down? And now that masks are mandatory, what's the best way to make them and safely look after them? On today's show: * What do we do if numbers don't start coming down soon? * Why aren't the numbers coming down? * Dr Norman gave his recommendation for materials for masks. What are they? * What should I look for when buying a mask? * Can I put my cloth mask in the microwave and it will kill the germs? * My husband was given some surgical masks and was told he could rotate them every three days. Is this true?

Record numbers in Melbourne. What happened to stability?
There's been a record number of new daily cases of coronavirus in Melbourne, just days after health authorities were hoping numbers had stabilised. It's now more than a week since Melbourne went into lockdown, but so far there's been no sign the massive outbreak is being suppressed. And the numbers are also growing in NSW, where authorities are saying the incubation period of the virus could be as low as a day. On today's show: * What do authorities mean by "stability"? Could they know more than they're saying? * NSW authorities say the incubation period of the virus could be a day. What does that mean? * I work at an outdoor grocer. How do I wear a mask for a eight hours? * What does Norman think about loads of people going to the AFL in WA? And we have some research on a really interesting study about how well masks worked at a salon in America.

Melbourne's lockdown is a week old. Why no decline in cases?
Melbourne has now been in lockdown for a week, and yet we're still seeing hundreds and hundreds of new coronavirus cases every day. And the city's hotspot suburbs have had restrictions for even longer. Health authorities are saying that the numbers are showing signs of some stabilisation but it's still too early to tell for sure. So are the restrictions working and when should we start to see a decline in cases? On today's show: * Melbourne has been in lockdown for a week. Why haven't we started to see a decline in cases? * Health authorities are talking about signs of stabilisation of numbers. Is that true? * If the outbreak in NSW can be linked to Victoria, was NSW about to eradicate the virus? And we received a bunch of comments on yesterday's show. Norman and Tegan respond to your concerns about elbow bumping, the efficacy of loose fitting masks and suggestions on how to get more people to wear them. And we have some research from the New England Journal of Medicine about…

Are pubs petri dishes that should be shut down and avoided?
Going to the pub is almost a national sport, which is why the following question might be a little controversial. In a pandemic, should pubs be closed to try and stop infections? The coronavirus outbreak in the Crossroads Hotel in Sydney has now hit 30 cases, and may be starting to cause problems with surrounding businesses like gyms. So should pubs - heaving places with lots of mixing and movement - be closed? On today's show: * Are pubs places to avoid? * Runners come too close to me. Could I get coronavirus from them? They breathe a lot. * What about gyms? Is it still safe to go to them? * I can't breathe when I wear my woven cotton mask. What should I do? * Can you get coronavirus via the eye? * If a person coughs/sneezes into their elbow and covers that part of their arm with droplets, is it not unhygienic to then bump elbows, instead of shaking hands?
Jul 13, 2020
Melbourne was first. Is it now Sydney's turn?
The growing numbers of coronavirus cases from Sydney's Crossroads Hotel has shown that Melbourne is far from alone in having to worry about outbreaks. The venue has so far been linked to more than 20 cases from people who either picked it up while at the pub, as a contact of someone who'd been there, and even as a contact of a contact. So will NSW Health be able to get on top of it? Or could this be the beginning of some big problems for Sydney? On today's show: * Are we watching the start of a Sydney outbreak in real time? * With all the new cases popping up in Sydney, should we be heading back into lockdown now rather than waiting? * Norman said touching a face mask can reduce or impair its effectiveness. How or why does this happen? * Europe has reduced some restrictions. Why is there not a spike in cases? * I was disappointed about Norman’s reference to healthcare workers contracting diseases as 'inexcusable'. What did he mean by that?

Is it too late to eliminate coronavirus, even if we wanted to?
There have been hundreds more cases of coronavirus over the weekend in Victoria, with more and more outbreaks popping up. New South Wales is also battling its own outbreak, which has come from a pub in south-west Sydney. With the amount of virus now washing around the community, has Australia missed its chance at eliminating coronavirus even if it wanted to? On today's show: * Has the surge in cases in Victoria peaked yet? * Why are there so many cases per day in Victoria? * How do I prevent spread between household members when there is only one bathroom? And Norman and Tegan discuss a recent study in The Lancet about so-called herd immunity, and how even countries that have suffered terribly are still a long way away from enough of the population being immune.
Jul 9, 2020
With hundreds of cases this week, has Australia blown it?
Let's face it: it hasn't exactly been a great week this week for coronavirus. Victoria has outbreaks occurring all over the place, Australia's second largest city is in lockdown and other states and territories are terrified of cases flowing over to them. It's all looking very messy. So has Australia blown it? Or can we fight back against SARS-CoV-2? On today's show: * Has Australia blown it? * Should other states continue winding back restrictions and social distancing requirements? * How do we know if the virus is emerging? * Has the recommendation on masks changed? * Should I wear a mask? What about my baby?

Is Victoria the wake up call Australia needed?
Borders have been thrown up around Victoria as other states try to limit importing coronavirus infections. But it's been too late for the ACT and NSW, which yesterday had cases that were linked back to Victorian residents. It has kickstarted a lesson about if we've been too complacent with personal social distancing and relaxing restrictions. So is what's happening in Victoria the wake up call Australia needed? On today's show: * Is the rest of Australia ready for coronavirus? * What lessons can we learn from what's happening in Victoria? * Why has Victoria gone with a six week lockdown? * What does Norman have against the ACT? He never mentions Canberra on Coronacast. * What's the difference between droplets and aerosols? And why does it matter?

Melbourne's 42 days of lockdown. Will it work?
The number of new coronavirus cases in Melbourne has finally hit a high enough level for the Victorian Government to put the city back into lockdown. Melbourne will be in lockdown for the next six weeks, or 42 days, with people only being allowed out for four specific reasons: care, essential purchases, exercise and school or work. It's a remarkable turnaround from only a month ago, where elimination and international travel bubbles were on the agenda. So why put the lockdowns in now? Will they work? And why is it going to be so much harder the second time around?
Jul 6, 2020
Are Melbourne's current lockdowns enough?
There are now all sorts of different lockdowns in Victoria as the state's active caseload of coronavirus gets worse and worse. The number of cases has more than doubled in the last week, and is showing no signs of slowing down. Borders will be closed with NSW from midnight, a hard lockdown remains in place for residents in public housing towers and softer restrictions apply to people in hotspots. But is it all enough? Or is just delaying the inevitable citywide lockdown? On today’s show: * Are the measures in Melbourne enough? * Given Victoria's daily case count is higher than during the March peak will the whole of Melbourne go back to harder restrictions? And will school go back? * What’s the latest understanding of COVID-19's case fatality rate? And Norman and Tegan discuss the letter to the World Health Organisation, signed by more than 230 scientists, arguing that coronavirus is airborne. And also research in The Lancet which might indicate that we're worrying way too…

Is Melbourne becoming a nightmare?
The coronavirus situation in Melbourne is getting more and more serious, with hundreds of people in public housing units forced into hard lockdown over the weekend. The Victorian Government has announced a series of support measures for the residents of the high-rise buildings as they're unable to go out. It's a scary prospect for the residents, and a potentially nightmarish situation with hundreds of people living in densely populated buildings. On today's show: * Victoria has had a bad weekend. What’s likely to happen now? * I'm not in a Melbourne hotspot, but should I go to a dinner that was organised before the surge in cases or stay at home? * Is getting on a plane and flying to a job interview a good idea at the moment? We have a clarification about staying home after being tested in Victoria's testing blitz last week, and Norman has an update on how a few COVID-19 treatments are going and which ones the World Health Organisation has removed from its list because they do…

Cases are popping up in other states. Are we losing control?
If you've been watching the coronavirus news this week, you may have reacted with a bit of alarm after seeing that cases seem to be slipping out of Victoria and into other states and territories. The NT and NSW have reported cases that came from people travelling from Victoria, and contact tracing is underway. So as cases pop up around the country, Coronacast listeners are wondering: are we losing control? On today's show: * As cases spread beyond Victoria, are we losing control? * Why are we making such a big deal about the infections when clearly the hospital rate is almost non-existent? Norman and Tegan discuss some responses to yesterday's question about why people in Melbourne might be refusing to be tested for coronavirus. And it's Friday, which means it's time for the quick-fire round! * Are workers who are testing people tested for COVID-19? * Will our DNA be stored after taking the test? * In the UK there was a trial of a COVID-19 test that takes 20 minutes with no l…

Why are some people refusing to get tested?
With huge amounts of coronavirus testing going on, one of the more disturbing statistics is the number of people who are refusing to be tested. Victoria's Premier Daniel Andrews said on Monday that as part of Victoria's testing blitz, more than 900 people had refused tests. So why is it happening? Tegan and Norman go through our huge list of audience questions and comments to try and find out. On today's show: * Why are people refusing to be tested for coronavirus? * The virus doesn't recognise someone's home address as a boundary. Is it enough to single out just those suburbs in Melbourne for lockdown? * I have read that gastro-like symptoms have been a first symptom of COVID-19 in children. Should I get my child tested if they have these symptoms? * Norman mentioned on Wednesday that China was testing something on its military. Do you know anything more about that? * What are the rules when it comes to social distancing now in states where there is less virus?

Lockdown! Victoria's big move to try and stop coronavirus
Victoria has again forced large parts of Melbourne into lockdown, in an attempt to try and halt the spread of coronavirus. Listing postcodes in so-called "hot zones" where restrictions will apply, Victoria's Premier Daniel Andrews says the "extraordinary steps" were necessary to contain a surge in infections. The orders effectively place some suburbs back under the same restrictions from the start of the pandemic. So will it help stop the spread? On today's show: * Why are people in Melbourne being forced back into lockdown? * As cases rise in Victoria, why aren't we seeing more people in hospital like what happened the first time? * There hasn't been a treatment or vaccine for SARS and MERS, why do we think there will be one for coronavirus? * There are antiviral drugs for HIV, could we see a similar approach for coronavirus?
Jun 29, 2020
Why isn't Victoria locking it all down?
Victoria registered 75 new cases of coronavirus on Monday – one of the highest daily increases in new cases since the pandemic began. Last time the curve was becoming this steep, Australia was put into lockdown. And while that hasn't happened again yet, Victorian authorities aren't ruling it out. But if keeping coronavirus under control is so important, why wait? On today's show: * Is it time to get worried about Victoria? * If controlling community transmission is so important in containing the spread then why is the Victorian government not taking any measures? * Will you finally admit that Victoria is experiencing a second wave of infections? * Is diminished or loss of sense of smell a permanent or temporary complication of COVID-19? * Is it safer to fly in business class or does the air circulate regardless and make no difference on such a long trip? And Norman and Tegan discuss some research about COVID-19 in children and infants, which found that while most kids only…

The unrelenting slog facing the people trying to stop coronavirus
As case numbers in Victoria continue to rise, spare a thought for the people running the State Government's response to the virus outbreak. The small team needs to manage a growing number of active cases, find out who they've come in contact with and hope it all doesn't spiral out of control. To make matters worse, even if they manage to bring the latest outbreaks under control, there's little to stop it all flaring up again somewhere down the line. On today's show: * What's it like inside the Victorian Government's response to rising case numbers? * How is Victoria hoping to deal with the outbreak? * What's keeping Victoria's Chief Medical Officer Brett Sutton up at night? And a few recent studies have found SARS-CoV-2, the virus that causes COVID-19, in wastewater in Europe long before the first known cluster in Wuhan. So what's going on? Does this mean coronavirus could have been circulating long before we originally thought?

Can Victoria test its way out of its coronavirus problem?
Victorian Premier Daniel Andrews wants 100,000 Victorians to be tested for coronavirus over the next 10 days in what he calls an "unprecedented testing blitz". The blitz aims to find out where coronavirus is and isolate infected people, to try and get on top of that state's growing infection problem. So can Victoria test its way out of its coronavirus problem? Or are local lockdowns going to be needed? On today's show: * Can Victoria test its way out of its coronavirus problem? * How accurate are the saliva tests? * What's the strategy here of mass testing? * Why are we so worried about community transmission? The goal was always to flatten the curve, not eliminate the virus, wasn't it? * People want to elbow bump me. Is that a risk? It's also quick-fire Friday! * Should you put off routine dental checks or colonoscopy checks? * Is it true that women involved in trials of a coronavirus vaccine overseas have become infertile? * If 200 Australians were exposed to COVID-19, ho…

So did Conor McKenna have coronavirus or not?
The on again, off again nature of Essendon AFL player Conor McKenna's COVID tests has been a wild ride this week. McKenna had an irregular test result on Friday, then tested positive on Saturday. Then on Tuesday, tested negative. So what's going on? Did he have COVID-19? Or has he been clear all along? On today's show: * How much can we rely on COVID-19 tests? * What makes a super spreader? Is it biological or is it behavioural? * I tried to buy a pair of jeans today but my size was "out the back in quarantine for another 24 hours"! Would putting clothes in a plastic bag for 48 hours kill off any coronavirus? * Should people in the coronavirus hot spots leave their house to go to work?

Every coronavirus cluster starts with one person
If we've learnt anything from the Victorian coronavirus situation, it's that COVID-19 loves clusters. The first known cluster of coronavirus was the Wuhan wet market in China, infecting more than 40 people. From there, in only a few months, it has spread around the world, infecting more than 9 million people. So how do these clusters start? And how do we stop them? On today's show: * What's the latest in Victoria? * Are multicultural communities getting enough official communication about coronavirus? * I live in a Melbourne hotspot. Do you have any tips on what measures I should take? * What is "routine testing"? * How do clusters or hot spots start? And Norman has some more on "R values" of coronavirus and the flu. He also makes a correction to some comments in yesterday's episode about where the protester at the Melbourne Black Lives Matter protest was infected.

We've stopped social distancing and it's causing problems
A month or so ago, we had social distancing sorted. We weren't hugging or shaking hands and we were keeping our distance. But as the threat of coronavirus reduced, it seems we've slipped back into old habits. And according to experts, the complacency could cost us dearly. On today's show: * What is the "R value" for coronavirus nationally? What about Victoria? * What is happening to social distancing? Are we getting worse at it? * Could the spike in Victoria be due to the colder weather? * How does genomic testing of the virus work and is this how Victorian authorities know that the latest outbreaks are from family transmission? * When going to family gatherings, it's not pleasant when relatives are offended by maintaining physical distance from them. How do we do this better?

Coronavirus is taking off again. Is it the second wave?
The state of Victoria is now under more restrictions, after being forced to ratchet them up due to a rise in coronavirus cases. Victoria has had nearly a week of daily double digit increases of COVID-19 cases as coronavirus circulates. While the situation isn't yet as bad as it was before the lockdowns, it has health authorities and political leaders worried. So how did we end up in this situation? On today's show: * What's going on in Victoria? * Why don't state governments make people who test positive to COVID-19 go into forced quarantine? * Is the situation better or worse than when restrictions and lockdowns were first started? * For every person detected with a positive SARS-CoV-2 test, how many are in the community undetected? * What is actually a second wave? Does it mean small clusters breaking out here and there, or a big spread of the virus again?

What's social distancing done for sexually transmitted infections?
When Australia went into lockdown, it helped more than just coronavirus from spiralling out of control. Infections of influenza are massively down on average, thanks to social distancing and people staying home. So what about other illnesses like sexually transmitted infections? Has staying apart helped drive down those cases too? On today's show: * How do you manage dating and remain COVID-19 safe at the same time? * Can coronavirus be transmitted sexually? * What's social distancing done for sexually transmitted infections? * Was the virus present earlier than reported in those countries that suffered early on? * My Victorian family members insist there has been no community spread and new cases in Victoria and NSW are expats returning and in quarantine. Is this right, or is there a community trickle? * Do you think kids have better immunity because of all the vaccinations they receive during childhood? And in our new "quick answers" segment: * How do you get a COVID-19 te…

Can we trust the hype over steroids as a coronavirus treatment?
You might have seen the headlines over the past day or two about the drug dexamethasone, which claims to be a major breakthrough in the coronavirus pandemic. The drug is a cheap and widely used steroid, and reduced death rates by about a third among the most severely ill COVID-19 patients in hospital. But news of the drug's success in trials came not from a peer-reviewed scientific paper, but instead via press release and snippets on Twitter. So how much can we trust the results? On today's show: * What is dexamethasone and why is it being touted as a coronavirus treatment? * Beijing has been battling with a fresh outbreak of the new coronavirus. What’s going on?

The global hotspots where coronavirus is still killing thousands
As coronavirus restrictions are loosened in Australia, it's easy to forget we're still living in the middle of a pandemic and globally numbers are still rapidly growing. A COVID-19 tracker run by Johns Hopkins University in the US has the worldwide tally for coronavirus infections at over eight million cases. So where are the new hotspots and are any countries beginning a second wave? On today’s show: * There's more than eight million cases of coronavirus worldwide. Where are the hotspots? * My daughter is a bit of an anxious school avoider who sometimes feels "sick" to avoid going to school. Are there any tips to manage this during a pandemic where we must keep sick kids at home to avoid COVID-19 outbreaks? * And we continue our series looking at other countries. Today we talk about Japan!

The 'ludicrous' coronavirus certificate your boss wants
Proving you have coronavirus is easy. You get a test, and it comes back positive. But what if your boss or school asks you to prove you DON'T have it? According to the professional body for GPs, some employers and schools are asking people to provide a medical certificate showing they're clear of coronavirus. So why is a certificate proving you're COVID-19 negative impossible and a waste of time? On today's show: * Why employers and schools should stop asking for COVID-19 clearance certificates * Do researchers know why some people are asymptomatic? Is the virus only mild in these people, or can it be severe and they still show no symptoms? * Is SARS-CoV-2 the only virus where people are asymptomatic? * I have woken up with a sore throat and headache but am too scared to get tested. What should I do?

What if we can't stop unknown coronavirus cases?
While the number of new daily coronavirus cases in Australia is now mostly in single digits, there's still occasional cases of unknown origin popping up. It's also known as community transmission, and it's when health authorities get a positive test for COVID-19, but can't work out where the patient picked it up. So is this something we're just going to have to get used to? And what does it mean for phrases like eradication, elimination and suppression? On today's show: * What does eradication, elimination and suppression mean? And what’s the difference? * What does the term 'routine testing' mean? * How safe is it to play in a clarinet or flute ensemble even with social distancing? * Norman has mentioned diarrhoea as a COVID-19 symptom but it is never mentioned as a symptom that warrants testing. How often is diarrhoea a symptom of COVID-19? And Norman has some research about US poison control, which found a huge jump in the people being exposed to cleaning products and disi…

Protester tests positive. What happens now?
A protester at the Black Lives Matter demonstrations in Melbourne has tested positive to COVID-19. Victorian health authorities say the man was unlikely to have acquired the virus at the protest and may have been infectious at the time. Tracing possible contacts will be difficult, so what should people do if they were at the Melbourne protest? And what does it mean for Australia's overall response to coronavirus? Also on today's show: * What should you do if you were at the Melbourne Black Lives Matter protest? * Will there be a reduction in testing due to fear of testing positive and having to self-isolate? * My grandparents won't take advice to wash their hands saying they survived the war. How do I convince them it's worthwhile? And we continue our new segment talking about other countries and how they've responded to coronavirus. Today we're talking about Iran and fears that a second wave is already happening.

Does the World Health Org know what it's doing?
There's been all sorts of confusion this week, after a top expert at the World Health Organization seemed to suggest that people without COVID-19 symptoms rarely transmit the virus. The statement caused head scratching among experts, as asymptomatic transmission - that's giving the virus to someone when you don't have symptoms - is known to occur. The WHO has since clarified the statements saying they were "misunderstandings". So what happened and what could it mean for the WHO's reputation? Also on today's show: * If community transmission is erased, can we go back to normal? * What’s the latest on the COVIDSafe app? Is it still being used? * What is the risk of COVID-19 infection while flying? * Should I use a cloth handkerchief?

NZ has eliminated COVID. Is Australia on track to do it too?
New Zealand's Prime Minister Jacinda Ardern says she "did a little dance" when she found out her country finally had no more active cases of coronavirus. It means that the country is able to pretty much roll back most internal restrictions, meaning New Zealanders can now do what they want. So how far away is Australia from similar achievements? On today's show: * If NZ can be coronavirus free, is Australia far away? * For those who did attend the protests on Saturday, when is a good time to get tested? * My housemate emits long unguarded belches. Is there any COVID-19 risk? And we're starting a new segment where we'll have a look at a country to see how it's going, and what's been happening with COVID-19. Today we're looking at Italy.

So you went to the protests. Should you self-isolate?
With Black Lives Matters demonstrations being held in many Australian cities over the weekend, should protestors now be self-isolating in case they were infected? The AMA in Victoria says it’s necessary, but Federal Government advice is to get tested if you develop symptoms. So with thousands of people gathering for the protests, what's the chance there will be a rise in cases in the weeks ahead? On today's show: * I went to the protests. Should I self-isolate? * Is there a risk from hanging out with colleagues in stock rooms? * Can I start playing bridge again? Are the cards a risk? * Can you please talk about babies and pregnancy? And pharmacist owners have written to Norman, a bit annoyed that he said cold and flu products don't work. How will he respond?

The mysterious company behind a misleading coronavirus drug study
When the World Health Organisation saw data from a study into a possible coronavirus drug treatment, it immediately halted trials for safety reasons. The data implied that use of the drug hydroxychloroquine didn't help COVID-19 patients at best, and was even possibly harmful. But it turns out that the data were suspect, misleading and based on some pretty weird assumptions. Today, the story of a mysterious company that changed coronavirus treatment policies, and has called into question how medical studies are published. Also on today's show: * How do I stay safe from coronavirus if you’re planning to demonstrate or go to a rally.

Coronavirus can take away your taste. Why?
One of the main symptoms of coronavirus is loss of taste and smell, but it causes all sort of angst and concern to people who suffer from it. While many recover their senses in a few weeks, others have to wait far longer. So why is loss of taste and smell such a strong symptom for COVID-19? On today's show: * I lost my sense of taste. What's going on? * I'm seeing TV ads for cough syrup and colds, should there also be messages to get a COVID-19 test? * My wife and I have just had a child and I’m wondering what the latest info is around the impact of COVID-19 on newborns?

Why coronavirus tests are far from perfect
The accuracy of coronavirus tests has been again thrust into the spotlight, after a man who authorities said died from COVID-19, actually didn't. When 30-year-old Nathan Turner died last week, Queensland Health said he had tested positive to COVID-19. But further testing showed that he was negative. So how did the test get it wrong, and how common could it be? On today's show: * How do you even get a false positive? * How is the coronavirus death rate calculated? * If Australia is locked down, where would a second wave come from? * Why are there still cases in hotel quarantine?

Could rallies in the US cause a coronavirus uptick?
As riots rage across large cities in the United States, some are happening right in the middle of major COVID-19 hotspots. Thousands of people have already died from the virus in cities like Washington DC and New York, and the epidemic is still not under control. So what could it mean for America's response to coronavirus? On today's show: * What could US riots mean for coronavirus cases? * Why are so many schools in Israel closing? * Is there any evidence that masks work? And Norman has a study of COVID-19 patients with diabetes, which shows that 10 percent die within seven days.

Hello Winter! Is coronavirus about to get worse?
As the days get shorter and colder, many people are wondering what it might mean for coronavirus infections. One theory states that countries in the northern hemisphere have suffered more because they were in their winter months. So as Australia ticks over to a new season, could the weather play any part in the severity of an epidemic here? On todays show: * What might winter mean for coronavirus? * More Ruby Princess, but this time it's a tuberculosis problem * What's going on with Victoria? And Norman has some more information regarding a question from last week's episode about the accuracy of coronavirus tests.

So what's the chance your coronavirus test is wrong?
So you've just had a coronavirus test, and had a little stick shoved up your nose and wobbled around. But while you’re waiting for a result, have you thought how accurate it might be? Turns out the so-called false negative rate - that's when positive cases are wrongly found to be negative - can be as high as one in three on average. What might that mean for Australia's fight against the virus? On today's show: * Can I get married in India in November? * Do vaccines need to be 100% effective to be good? * How accurate are coronavirus tests? And we have a special announcement about the Together in Art Kids exhibition. Meet one of the kids who has submitted some amazing work, and the next artist who will help curate the next round of submissions. If you want to see the art from the "Inner Worlds" exhibition, visit the Together In Art website (search for Together In Art Kids or find the link on our website).

Has the COVIDSafe app been worth it?
It's been just over a month since the Federal Government released the COVIDSafe app to help contact tracers track down potentially positive COVID-19 cases. It was sold as a vital tool to reopen the Australian economy and help get things moving again. So how has the app been used since then? Has it been the key to get things moving or has it been forgotten? On today's show: * What’s the history of the app so far? * How many downloads has it had? * Is it still being sold as a vital tool? * Why isn't the Government being transparent about the app’s functionality? * What successes has it had? * Has the source code been released? * How many people have since deleted it?

Just when you thought it was safe to go outside again
You might have thought we were finally getting on top of coronavirus, but the pandemic is not without its surprises. There's been a few cases in the past few days that have health authorities scratching their heads. Two school kids in Sydney have tested positive, and there's a case in Queensland that apparently dates back to the Ruby Princess. So what's going on? And what might it say about the level of community transmission of the virus? On today's show: * What do the cases in Sydney schools mean for community transmission numbers? * Is coronavirus more common out in the wild that we thought? * How can there be another case from the Ruby Princess? * Are enough people still getting tested to give a true indication of the spread? And Norman's here to explain the latest from the vaccine trial that's just started in Australia. But how can they test it here if there are such low active cases?
May 25, 2020
Which mask is the best? What should you avoid?
There are all sorts of options when picking a mask to help protect yourself and other people from picking up coronavirus. But some masks can be expensive, and not every mask is equal. Firstly, you have to wear it correctly. Secondly, you want to make sure it's doing what it is supposed to. So what mask should you choose? On today's show: * What mask should I wear and can I make my own? * What’s going on with state border closures? Is there any point? * Can smoking help inhibit coronavirus? And Norman and Tegan discuss a few pieces of research about how long coronavirus may be infectious for.
May 24, 2020
Is it finally time to hug your grandparents again?
At the height of the Australian coronavirus epidemic, older people were urged to stay away from children and grandchildren to avoid contracting the virus. Age is a major risk factor for COVID-19, and many older people made the emotional decision to stay away from loved ones. But as the number of active cases continues to fall, families are wondering if it's okay once again for grandparents to hug and be around their children and grandchildren. On today's show: * Is it ok to hug our parents again? * What should people aged over 70 be doing now? * Why is it ok for kids to go to school, but not visit grandparents? And Norman talks about a study how coronavirus affects the immune system and what it could mean for designing treatments.

How complacency could trigger a third wave and force us back indoors
We know that in the 1918 flu pandemic the second wave was far more deadly than when it first arrived. This time around in Australia, it seems we may avoid a terrible second wave but that may make us more vulnerable to a third wave. By the end of this year and into 2021, we'll have little natural immunity, a vaccine may not be available and there's a danger that complacency may have set in. On today's show: * Norman goes on a bit of a tear about masks, and says if we all wore them we could re-open society much more quickly * How should social distancing work on flights? * Will any second or third coronavirus wave be better or worse than the 1918 flu?
May 20, 2020
Coronavirus loves lungs. Does it also lurk in our blood?
When coronavirus infects someone, we know they can spread the disease via coughing and sneezing. But what about other forms of bodily fluid like blood? Around the world, there have been no reports of transmission that have definitely proven blood to be the cause. But the virus has been found in our blood, so it is theoretically possible. So what could this mean for blood donations? On today's show: * Is giving blood safe? * If someone with the virus coughed or sneezed on another's open wound, can the virus get into the bloodstream then the lungs? * Is there a chance we've eradicated the seasonal flu seeing as its infection rate is much lower than coronavirus? * If there are no new cases and haven't been for a while, like in WA, why do we need to continue with social distancing?
May 19, 2020
The race for a coronavirus vaccine may have a frontrunner
The search for a coronavirus vaccine has taken a small step in the right direction, with promising early results from a vaccine trial. Made by biotechnology company Moderna, the very early findings indicate the vaccine is safe and doing what it needs to do. But the results now need to be repeated in thousands more people to see if the vaccine works in the real world. On today's show: * What is this Moderna vaccine all about? * It appears that five sailors on USS Theodore Roosevelt have been reinfected or tested positive after recovering from infection. What does this imply for immunity? * Because we've been at home for so long without going out much, when we do start going back to school and work, will we become more likely to catch colds? Also, Norman and Tegan have a chat about bats, and Norman has some research about one of his favourite topics: the faecal oral route.

Is social distancing 1.5m enough to avoid coronavirus?
As pubs and restaurants re-open in some states, you're probably thinking that it's safe to return as long as you maintain 1.5 metres distance from other diners. But the 1.5 metre "rule" for social distancing is really just a best effort recommendation, and isn't a guarantee. So are social distancing recommendations enough when you're in a closed space for a long time? On today's show: * Can COVID-19 be spread through the air-conditioning? * Will social distancing save me? * Is it true that no scientist has physically isolated an actual COVID-19 virus that can be viewed under a powerful enough microscope? And Norman and Tegan talk about some exciting research about antibodies.

42 days of infection? When coronavirus won't go away
You probably think that coronavirus is a disease that takes 14 days to get over. That's how long isolation periods last. But for some people, coronavirus is a slow burn, making them sick - sometimes critically - and keeping them infectious for weeks. For example, we're still hearing about cases being connected back to the Ruby Princess, which docked in Sydney in March. And while rare, some patients remain infectious for longer than a month. So if some people remain infectious much longer than we think, could we get caught out if they go undetected? On today's show: * How long can people remain infectious for? * Is the easing of restrictions because there’s less virus around or that we’re better at responding to outbreaks? * Has SARS1 and MERS disappeared? And we have all your creative, wonderful and scary ways to blow out birthday cake candles, without blowing on the cake.
May 14, 2020
Will coronavirus kill off birthday candles and choirs?
When you start thinking about it, coronavirus is going to change so many things we previously took for granted. Birthday cakes for example. It's probably not a great idea to be blowing out the candles. And if overseas experiences are anything to go by, loud boisterous singing in choirs may also be problematic. So what else might change? On today's show: * Is the risk of transmission high for those singing in choirs? * How do I blow out candles on a cake? * How do asymptomatic people transmit the virus if they're not coughing? * I was tested a few weeks ago because I had a sore throat. It's back. Should I get tested again? * Does coronavirus cause the common cold? There's no vaccine for that. * Does everyone who gets coronavirus develop COVID-19? * When you say 'kids', what do you mean? * I haven't worn shoes for a while. Now my old shoes hurt. Can my feet get bigger?

How much coronavirus research is useless and wasteful?
Ever since coronavirus appeared, scientists and researchers around the world have been scrambling to find out as much as they can about it. So much so that there's now enormous overlap in trials and reviews of COVID-19 evidence. It's led to concerns that resources are being wasted, especially in areas of drug trials because many studies are poorly designed and not actually revealing any useful information. On today's show: * How much coronavirus research is wasteful? * What's the point of quarantine if some people remain infectious for more than two weeks? * If I have a flu vaccination and get a slight reaction do I need to be tested for coronavirus?
May 12, 2020
Was coronavirus 50 years in the making?
There are all sorts of coronavirus origin stories, ranging from secret US military plots to disastrous accidental leaks from Chinese labs. But studying the evolutionary history of the SARS-COV-2 virus reveals that those stories are unlikely. So what is the most likely explanation for where the virus came from and could it be that it's been circulating in humans for far longer than we think? On today’s episode: * We revisit some of the origin stories of the novel coronavirus * If someone is asymptomatic with COVID-19, what's the maximum time they could be contagious? * Is it true that people who recover from the virus are left with serious holes in their lungs? And Norman talks about a paper that looks at a tuberculosis vaccine and if it could be useful in protecting against COVID-19.

Weighing up death. The cost of lockdowns vs no lockdowns
The way different countries have responded to coronavirus has been incredibly varied. Some have tried to keep as much open as possible, others have gone for hard lockdowns at enormous economic cost. Australia has been towards the stricter end of the scale. So was it worth it? Will it end up costing more lives than it saved? On today's episode: * What are the recommendations for getting kids tested? * What if you know someone has COVID-19 symptoms but isn't getting tested? * Could we train dogs to sniff out coronavirus? * Is it safe to re-enter the pool? And are the lockdowns worth the cost? A few articles lately say yes, both in economic terms and total lives saved.

As restrictions ease, here's how to avoid the virus
Most states and territories are moving to the next phase of our coronavirus pandemic journey, with some public spaces reopening, larger public gatherings permitted and an increase in the size of our social bubbles. But as we creep back into the world, there is always the risk of another outbreak. On today's Coronacast, Dr Norman Swan and health reporter Tegan Taylor discuss some simple ways you can keep yourself healthy and coronavirus-free while also enjoying your new freedoms. Also on the show: * How we can beat the Prime Minister's goal of reopening Australia's economy before July? * What are sentinel tests and why are they so important in Australia's coronavirus fight? * If so many COVID-19 cases are asymptomatic, will ramped-up testing lead to a massive spike? Tegan and Norman also look at some modelling from Sydney University that predicts a suicide epidemic curve, but also shows what can be done now to flatten it. If you or someone you know needs help, call Lifeline on 1…

Has coronavirus really split into two strains – and does it matter?
You might have seen the study that found there may be a more contagious strain of coronavirus floating around. It turns out though that it's quite a controversial paper, and some experts are downplaying the findings. For starters, the more contagious strain is already the one that's in Australia. And secondly, while it may be more contagious it's no more dangerous than the other strain. On today's show: * I heard there are two strains. What’s that about? * Is there an accurate antibody test yet? * Would testing for antibodies at the airport mean I could avoid 14-day quarantine if I'd already had COVID-19? * I live in Australia and got sick before Christmas with coronavirus symptoms. Could I have had it? * Can Norman be President of the USA? And Norman's found a study that looked at anti-vaccination views and what that might mean if there's ever a SARS-COV-2 vaccine.
May 6, 2020
Why might coronavirus become more "gentle" in time?
Like all living things, coronavirus will evolve and mutate, but that's not necessarily something to be feared. While the virus that causes COVID-19 is dangerous and deadly, if history is anything to go by, any mutations may calm it down a bit. In fact, a mutation might be in the interests of both humans and the virus. On today's episode: * When does it turn from a blip in cases into a second wave? * What should I do if someone needs CPR? * Why might SARS-COV-2 turn into a more "gentle" virus? * Is the virus blood type specific? And Norman has a very interesting piece of research from France. The research found a patient who had the SARS-COV-2 virus in December - a month before the country's first reported case. And the patient had no travel history to China.

What's behind the sudden uptick in coronavirus cases?
One of the realities of this coronavirus pandemic is that you think you're doing a good job and then suddenly there's an outbreak. Some states might be consistently reporting zero cases, but others are struggling with growing clusters. So why has the infection rate suddenly increased? On today's episode: * Is the uptick in cases because of people travelling at Easter a few weeks ago? * Should I be worried about the increased number of cases? * Will salt in my homemade salami kill coronavirus? * We can't travel to other states yet. Isn't it a bit early to travel to NZ? * Is it possible Ebola and coronavirus can mutate into a more potent virus? And Norman has some news from a research paper about heart medication, which found it didn't worsen the disease for people who got it or make them more susceptible to it in the first place.
May 4, 2020
Is there any possibility coronavirus escaped a Chinese lab?
The origins of coronavirus have become increasingly controversial, with the US Government ratcheting up the rhetoric in recent days. US Secretary of State Mike Pompeo said recently there was "a significant amount of evidence" that it emerged from a Chinese laboratory. According to geneticists, it's unlikely the virus was man made. So what are some possible beginnings of the pandemic? On today's episode: * What are some possible origins of coronavirus? * Are you more likely to get coronavirus if you work in an abattoir? * Can I get sick from meat processed in an abattoir if the worker had coronavirus? * Could herbal medicine play a role in helping stop or treat coronavirus? And Norman and Tegan discuss research regarding skin rashes that are being reported by some COVID-19 patients.

Why the next fortnight is so important in the coronavirus battle
This weekend, for the first time in a long time, you may have gone out to see a friend, sat in the park or had a picnic. With restrictions in some states slightly lifted, does that mean we're finally turning a corner on the coronavirus pandemic? Possibly, but the next 14 days will be crucial. On today's show: * What's going on with school openings? * How important is Vitamin D and what role could it play in COVID-19 infections? * Could low blood oxygen be used as a way to see if someone has COVID-19? And Norman has some information from a yet-to-be-published paper about why some South Korean recovered patients seem to be testing positive again for COVID-19.
Apr 30, 2020
What is remdesivir and what's all the fuss about?
An experimental antiviral drug called remdesivir is being touted as a possible treatment for COVID-19 patients. An unpublished, non-peer reviewed trial from America has found that it seems to lower the time patients spend in hospital, and might help reduce death rates. So how excited should we be about this drug? On today's show: * What's remdesivir? * Where does it come from? * What do we know about side effects? * What about that study from China that found it provided no benefit? * Is lifting restrictions now too risky? * What does all the research into SARS-CoV-2 mean for the common cold?

Are kids and young people affected more badly than we thought?
Several worrying cases involving coronavirus infection of children and younger adults have emerged from the UK and USA in the last few weeks. In the UK, a few children have shown up at hospitals with a serious illness. And in America, younger adults have shown up at hospitals after suffering from strokes. While the total numbers are low, it reveals there's still a lot we don’t know about this virus. On today's show: * What is happening with children in the UK? * What about younger adults suffering from stroke in America? * Is loss of sense of taste and smell a good enough symptom to get tested? * How does COVID-19 possibly change the way we think?
Apr 28, 2020
Were Australian lockdowns worth it?
As states slowly wind back restrictions and release the brake on lockdowns, it’s a good time to look back to see if they were worth it. So far, Australia has had less than 100 deaths related to COVID-19, and new case numbers remain small. But what about deaths that occurred because of the lockdown? And how many deaths would have occurred anyway? On today's show: * Were the lockdowns worth it? * Why is the tracing app critical time set to 15 minutes? * When is it likely that we will be able to travel interstate again?
Apr 27, 2020
So should we download the coronavirus app or what?
The Federal Government's contact-tracing app has smashed expectations and has been downloaded more than two million times since its release. It's hoped it will help track down contacts of confirmed COVID-19 cases, but there is still a lot we don't know about the app. And is there any evidence that it will even help? Today, Coronacast is joined by tech reporter Ariel Bogle from the ABC's science unit to help answer your questions. On today's show: * What is the COVIDSafe app supposed to do? * Is it spying on me? * Is being fit and healthy a good thing to help tackle coronavirus? * What happened to all those suburb hotspots? * Is there a possibility of infertility occurring from this virus? And Dr Norman Swan has a study that dives into antibodies, which might give us some clues around immunity.
Apr 26, 2020
Is being overweight a bigger risk factor than smoking?
Data from overseas suggests that after age, obesity is the biggest risk factor causing more problems than smoking with coronavirus patients. So why could that be? On today's show: * What's the NSW schools report all about? * Queensland is reducing some restrictions. Why now? * People are volunteering to be exposed to coronavirus to help test the vaccine. Is that a good idea? * What is the role of obesity in serious outcomes from COVID-19? * Why do I need a flu shot to visit my father in an aged care home? * Are vegans and vegetarians the least affected by COVID-19? And don't forget to check out Dr Norman Swan's "The Health Report" podcast for more on the issues around volunteering for the coronavirus vaccine.
Apr 23, 2020
How do we avoid the dreaded second (third or fourth) coronavirus wave?
Whichever way you look at it, coronavirus is going to be with us for quite a while. Elimination seems unlikely and overseas it’s infecting people in large numbers. While cases remain low, there's always the risk of it reappearing. So how do we avoid getting smashed by waves of coronavirus again and again and again? On today's show: * How do we make sure that our health system and economy doesn't get smashed every time there's a coronavirus wave? * In a previous episode, Norman mentioned that coronavirus might come back in two or four years. Where would it go in between? * Why do people often suffer more from COVID-19 in the second week? And we are joined by two time Archibald Prize winner Del Kathryn Barton! She's here to talk about the Together In Art Kids project — an exhibition featuring kids' artwork about the coronavirus. For more information, see togetherinart.org/kids

Human vaccine trials begin! What happens next?
Human trials for a coronavirus vaccine have begun in the UK, and it's all actions go. Depending on what happens there’s a long way to go before you might be innoculated. Usually the process could take years, but this isn’t your usual vaccine trial. On today's show: * What are the phases of vaccine trials? * Wasn’t the vaccine 18 months away? * Are death rates worse in hotter or cooler climates? * Will we see a better flu season because everyone is indoors? And Norman has found a paper from Nature Medicine, published in 2015, that has some spooky predictions about the current pandemic.

SPECIAL: Deputy Chief Medical Officer answers your questions
Why aren't we being told to wear masks? Are we trying to eradicate coronavirus or what? What’s going on with schools? There are so many big coronavirus questions Australians have, so we asked the country’s deputy Chief Medical Officer Paul Kelly to come on the podcast to help answer them. On today's show: * What’s the deal with masks? * Why does the Federal Government seem to have different views to the states on schools? * How do you socially distance and go to school? * Why have you shut playgrounds but not schools? * Can we eradicate coronavirus? * If you knew what you know now, what would you do differently?
Apr 20, 2020
When might Australia reach zero coronavirus cases?
New Zealand has announced it will soon loosen restrictions, as the number of cases there has continued to fall. So when might Australia reach a low enough caseload to consider doing the same thing? On today's show: * If Australia and NZ had low cases, could there be a “bubble” where we can travel between each country but no where else? * How far does Norman think Australia is away from zero or near zero cases? * If Australia goes for elimination, do we risk creating a COVID-19 vulnerable population? * Is there somewhere in the middle between zero cases and New York/Italy, eg Sweden? And Norman explains research from the journal Science about what the world could look like post-pandemic.
Apr 19, 2020
Why can't I test myself for coronavirus at home?
As getting a test for COVID-19 becomes far easier in Australia, people are starting to wonder why you can’t just do it yourself at home. On today's Coronacast, Dr Norman Swan explains while getting tested is easy, making sure you do it properly is a lot harder. On today's show: * When does the virus show up in testing? * Why can’t I do a test at home? * If anti-bodies are low in recovered patients, what does that mean for any vaccine? * What is the latest on vaccines? * What’s going on with the possible treatment using the drug remdesivir? And Norman gets a scalding from a three-year-old listener.

'No bare bottoms!': Norman Swan weighs in on corona-farts
It's the question everyone wants to know: can you get coronavirus from farts? Dr Norman Swan has a strong opinion on fighting the scourge of corona-farting, and asks Australians to make yet another sacrifice. We promise the rest of the episode isn't as silly. It's actually very interesting. In today's episode: * Are Australian governments trying to eliminate coronavirus, but just aren't telling us yet? * When do you know if you’re sick enough to go to the hospital? * Can microwaves kill coronavirus? * Can you get coronavirus from farts? And Dr Norman Swan discusses some research from Nature Medicine about when people are most infectious with the SARS-Cov-2 virus.

The search for a coronavirus vaccine and the challenges we're facing
Scientists are desperately searching for a coronavirus vaccine, but before that can happen there's a whole bunch of stuff they need to discover. One of those things is working out how the body's immune system responds to the virus that causes COVID-19. It has implications not only for vaccine discovery, but also how long people may stay immune after recovering. On today's show: * Anti-bodies. What are they and how do they work? * Is there a test that can detect them? * How long might you stay immune after a vaccine or infection? And we're also joined by Professor Declan Murphy from Melbourne's Peter MacCallum Cancer Centre to discuss the worrying phenomenon of cancer patients who may be frightened to continue their care because they're worried about picking up the virus while visiting the doctor.

Australia is doing well. But where are we heading next?
In the scheme of things, Australia is becoming a bit of a poster child for how to handle the coronavirus pandemic. Helped by having no land borders and by locking things down relatively quickly, the number of positive cases is now low. But that can change quickly. Today on Coronacast, where are we headed? What could life look like in the weeks ahead? On today's show: * Why are death rates different from country to country? And Dr Norman Swan also talks about some research on how effective school closures are on controlling coronavirus spread.
Apr 13, 2020
Why flatten the curve when we could eradicate coronavirus?
Forget flattening the curve. There’s a radical approach to coronavirus that could have us out of our houses and back at work or school without having to worry about the virus. It's called eradication, and it’s New Zealand goal. If they pull it off they could end social distancing in a month. We're also joined by Professor Ian Hickie to answer your questions on mental health. On today's show: * What are the best mental health strategies for people self-isolating on their own? * What do people do who have major pre-existing depression and are living alone? * What do I do for loved ones who have a mental health issue? * I am hating all these Zoom parties. Is this just the introvert life or am I coping worse than I think I am?

Do animals get coronavirus? We answer more kids' questions!
Scientists have given coronavirus to ferrets, dogs and cats to try and find out how the virus works. It turns out some animals can contract and potentially spread coronavirus – and that includes household pets. In today’s Coronacast, Dr Norman Swan and health reporter Tegan Taylor answer more questions from kids about the pandemic. On today's show: * James asks why is the coronavirus also called COVID-19? * Finn asks does it make animals sick? * Estelle asks when can I see my grandparents? * Alice asks why do adults get coronavirus worse than children? * Oliver asks how close are we to discovering a vaccine for COVID-19? And don’t forget about the Together In Art Kids project! See our website at abc.net.au/coronacast for more information.

You've probably heard these coronavirus myths. Did you fall for them?
A week ago, we put the call out for coronavirus social media myths and asked you to send them in. And we got a lot of them. One of the most common was a fake email that says it’s from a staff member of a hospital. It contains a whole list of tips like don't drink cold water, and offers ways to check at home if you have coronavirus. So we took the claims, and put them to Dr Norman Swan. Some of the email myths checked on today’s show: * Do you only have a cold if you have a running nose? * Does coronavirus die if you warm it up to 27 degrees? * Should you drink hot liquids and avoid drinks with ice? * Will salt water protect you? * Is there a way to check if you have coronavirus by breathing in deeply and seeing if you cough? Also, since it’s Easter, we ask Norman if eating chocolate while in quarantine is a bad thing. And Norman has an exciting announcement. To find out more, check out our website at abc.net.au/coronacast

How to get groceries without bringing home coronavirus
One of the few things we're able to do with social distancing is go to the supermarkets. We've had heaps of questions from people who are wondering the best way to stay safe. So if you have to visit the supermarket this Easter, here's a few tips to avoid getting coronavirus when you're out and about. On today's show: * How far should I keep away from other customers? * Should staff be wearing masks and gloves? * What are the chances of picking up coronavirus from products on the shelves? * Is it a good idea to sterilise stuff I buy when I get home? * How do I make disinfectants at home? * Still not sure how to wash fruit and vegetables. With detergent? * Does boiling water kill the virus? * How long does coronavirus last in the fridge? Freezer? * If I coat my hands in soap, is that enough? We are looking for questions about mental health for an episode next week, so send them in with CORONACAST in the question at abc.net.au/coronavirus

The second week crash. Why Week Two as a coronavirus patient is so scary
British PM Boris Johnson’s health has deteriorated as he enters the second week of being diagnosed with COVID-19. The 55-year old's experience is what many people have gone through, but it shows the dangers people often face in the later stages of trying to fight off the virus. Today, Dr Norman Swan explains why it is known as the second week crash.
