The TWiVians present an imported case of yellow fever in New York City, and explain how a dengue virus subgenomic RNA disrupts immunity in mosquito salivary glands to increase virus replication

Sharon and Scott return to TWiV for a Zika virus update, including their work on viral evolution and spread, and whether pre-existing immunity to dengue virus enhances pathogenesis.

Sharon and Scott join the TWiV team to talk about their work on dengue antibody-dependent enhancement of Zika virus infection, and identifying the virus in mosquitoes from Miami.

In the second of two shows recorded at the University of North Carolina in Chapel Hill, Vincent meets up with faculty members to talk about how they got into science, their research on RNA viruses, and what they would be doing if they were not scientists.

From the twiVivants, follow up on FluMist and Zoster vaccines, Zika virus update, and isolation of a multicomponent animal virus from mosquitoes.

Zika virus spreads in the USA, a Zika virus DNA vaccine goes into phase I trials, and how mosquito bites enhance virus replication and disease, from the friendly TWiFolk Vincent, Dickson, Alan, and Kathy.
