This Week in Virology

In his weekly clinical update, Dr. Griffin apprises us about the first case of highly pathogenic influenza in Canda, children dying of influenza infection and novel genetic reassortments of the virus, the Marburg virus outbreak in Rwanda, number of mpox infections, before reviewing the recent statistics on SARS-CoV-2 infection, the WasterwaterScan dashboard, how scientific mistrust has affected COVID-19 vaccine administration, resolution of the FDA hold on Novovax’s combination influenza and COVID vaccine, where to find PEMGARDA, how Paxlovid SAVES you money, when to use steroids to treat COVID-19 and how trace amounts of cytokines elicted during SARS-CoV-2 infection negatively impact cardiac function.
