A new virus showed up in China late last year, and it’s making its way to other countries too. So what do scientists know about the virus so far? And how worried should we be? To find out we talk to infectious disease researchers Dr. Kristian Andersen and Dr. Catharine Paules, physician Dr. Hui, and director of the National Institute of Allergy and Infectious Diseases Dr. Anthony Fauci. We did an episode on a *fictional* pandemic, which you can find here: https://gimletmedia.com/shows/science-vs/49hok3/pandemic  Check out the full transcript here: https://bit.ly/2S7JwXN Selected references: The WHO and the CDC are maintaining information centers that update regularly: https://www.who.int/emergencies/diseases/novel-coronavirus-2019 and https://www.cdc.gov/coronavirus/index.html  Scientific journals The Lancet and the New England Journal of Medicine have taken down the paywall for papers related to the outbreak: https://www.thelancet.com/coronavirus and https://www.nejm.org/coronavirus  This episode was produced by Wendy Zukerman, Meryl Horn, Rose Rimler and Michelle Dang.
