The TWiV team returns this week to SARS-CoV-2019 coverage to review the latest epi curves, the fatality rate, furin cleavage site and receptor binding domain in the spike glycoprotein, related CoV recovered from pangolins, evidence that the virus did not escape from a laboratory, and many more questions sent in by listeners.

In this week’s coverage of the coronavirus epidemic, the TWiV team discusses the fatality rate, China’s initial reaction to the outbreak, conspiracy theories, how long the virus remains infectious on surfaces, and evidence for virus in the intestinal tract.

From the European Congress of Virology in Rotterdam, Vincent and local co-host Ben Berkhout speak with Ron Fouchier, Rosina Girones, and Marie-Paule Kieny about their careers and their work on influenza virus, environmental virology, and developing an Ebola virus vaccine during an epidemic.

Vincent visits the Smithsonian Institution and speaks with Sabrina Sholts, Jon Epstein, and Ed Niles about the exhibit Outbreak: Epidemics in a Connected World.

Vincent, Alan, and Kathy continue their coverage of the Ebola virus outbreak in West Africa, with a discussion of case fatality ratio, reproductive index, a conspiracy theory, and spread of the virus to the United States.
