This Week in Virology

In his weekly clinical update, Dr. Griffin discusses the fourth US case of H5N1 human infection and reminds the audience of the definition of "pasteurization" before reviewing the recent statistics on SARS-CoV-2 infection, where to find PEMGARDA, the effectiveness of molnupiravir and dexamethasone, convalescent plasma, what to do when healthcare workers succumb to SARS-CoV-2 infection, how an EEG can be used to look for signatures of cognitive decline after SARS-CoV-2 infection and what we observed 2 years following SARS-CoV-2 infection for tissue-resident T cell and viral RNA persistence.
