TWiV reviews a fatal Alaskapox case, MERS in Kenya, diagnostic tests for Nipah and Lassa diseases, HPV vaccination rates in the US, cases of measles in Arizona and Minnesota, hepatitis C virus-derived RNA circles in infected cells, and prevention of respiratory virus transmission by resident memory CD8+ T cells.

TWiV reveals how viruses participate in the organomineralization of travertines, and how neutralizing antibodies evolve to exploit vulnerable sites in the hepatitis C virus envelope glycoprotein E2 and mediate clearance of infection.

Vincent visits Ohio State University (March 2020) and speaks with Shan-Lu, David, Amanda, Mark, Matt, Chris, and Qiuhong about their careers and their work on retroviruses, hepatitis C virus, coronaviruses, paramyxoviruses, and environmental viruses.

From the University of Texas at Austin, Vincent and Rich speak with Chris Sullivan about his work on miRNAs encoded in the genomes of polyomaviruses and papillomaviruses, and how an RNA triphosphatase restricts hepatitis C virus replication.

From the Karolinska Institute in Stockholm, Vincent speaks with Niklas Björkström, Ali Mirazimi, and Matti Sällberg about their work on the impact of chronic hepatitis C virus infection on NK cells, Crimean-Congo hemorrhagic fever virus vaccines, and immunotherapy to block entry of hepatitis B and D viruses.

Vincent travels to the University at Albany to speak with Cara, Rachel, and Alex about their careers and their work on stress granules, epitranscriptomics, and arboviruses.

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.

The TWiVerati revisit possible sexual transmission of Zika virus, and reveal how a cell protein that allows hepatitis C virus replication in cell culture enhances vitamin E mediated protection against lipid peroxidation.
