There have been many infections from the Diamond Princess cruise ship, which was quarantined in Japan for weeks. But it turns out it might have helped scientists get a better estimate on the fatality rate COVID-19. So, could it be a little less than we previously thought? And if so, why are there still so many people dying from it? On today's show: * The infection rate has halved over the last few days, what does that mean? * Is the way we test people possibly skewing the numbers? * Can I see my partner if we don't live together? * My hands are dry because I'm washing them a lot. Can I fix that? * Does UV/sunlight kill coronavirus? And Dr Norman Swan explains the research in The Lancet about mortality rates of COVID-19, compared to influenza and SARS.
