Richard Webby joins TWiV to review the history of avian H5N1 influenza virus, the recent change in epidemiological patterns, infection of dairy cattle in the US, and the risk of an outbreak in humans.
TWiV reviews avian H5N1 influenza virus in the US, measles at highest levels in England, positive selection underlies repeated knockout of ORF8 in SARS-CoV-2 evolution, and cross-species spill-over potential of the H9N2 bat influenza A virus.
TWiV explains a study of postacute sequelae of COVID-19 at 2 years, and airborne transmission of human-isolated avian H3N8 influenza virus between ferrets.
The TWiVers discuss the spread of African swine fever virus and its threat to pig farming, and the zoonotic potential of peste des petits ruminants virus.
