Incubation is a show about how viruses attack people – and how people fight back. This season, we talk to a scientist who fought the spread of Ebola while risking his life. We learn how a ubiquitous virus causes cancer and multiple sclerosis. And we hear how a mosquito-borne virus helped defend an empire. Stories of discovery, heartbreak, and heroic nerds drop weekly on Thursdays starting October 17th.
