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.

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.

The latest Zika virus news from the ConTWiVstadors, including a case of female to male transmission, risk of infection at the 2016 summer Olympics, a DNA vaccine, antibody-dependent enhancement by dengue antibodies, and sites of replication in the placenta.

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.

Project Premonition, a Microsoft Research project that uses drones to capture mosquitoes and analyze them for pathogens, preprint servers, and three mouse models for Zika virus induced birth defects are the topics of this episode hosted by the TWiumvirate and theirs guests Ethan and Jonathan.
