Lynda Coughlan joins the weekly virtual bus companions for a discussion of a host defense peptide from frogs that destroys influenza virus, and mouse models for acute and chronic hepacivirus infection.

Four virologists discuss our current understanding of Zika virus biology, pathogenesis, transmission, and prevention, in this special live episode recorded at the American Society for Microbiology in Washington, DC.

Preprint servers, the structure of an antibody bound to Zika virus, blocking Zika virus replication in mosquitoes with Wolbachia, and killing carp in Australia with a herpesvirus are topics of this episode hosted by Vincent, Dickson, Alan, and Kathy.

Nina Martin joins the TWiV team to talk about the movie Vaxxed, her bout with dengue fever, and the latest research on Zika virus.
