The TWiVmeisters discuss how copy-back defective viral genomes might modulate the clinical outcome of respiratory syncytial virus infection, and detection of antibodies to henipa- and filo-like viruses in Trinidad bats.

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.

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.

Scott Tibbets joins the TWiVists to describe his work on the role of a herpesviral nocoding RNA in establishment of peripheral latency, and then we visit two last minute additions to the Zika virus literature.
