In this episode, you'll learn about: R-naught and how it differs from Re, the effective R value; case-fatality rates and calculations as well as mortality rates; some defining factors of infectious disease presentations, including their incubation period, latent period, and serial intervals; different types of interventions that can be taken to slow the spread of a transmissible disease.
