TWiV 1106: Clinical update with Dr. Daniel Griffin
In his weekly clinical update, Dr. Griffin reviews recent statistics on the circulation of measles before addressing results of Pfizer’s phase 3 RSV vaccine clinical trial for adults under 60, RSV, influenza and SARS-CoV-2 circulation, differences between rural and urban communities dealing with SARS-CoV-2 infections, the latest statistics on influenza and COVID-19 circulation, restates the guidelines for spring administration of COVID vaccines boosters, discusses the emergency use application of a pre-exposure prophylactic. revised guidelines for how to treat respiratory viral infection guidelines by the CDC, continues to dispel the myth of viral rebound, revised guidelines SARS-CoV-2 treatment and how to treat respiratory viral infections, when to use steroids and the benefits of convalescent plasma, what do when healthcare workers succumb to SARS-CoV-2 infection, how long COVID affects the brain and associates with an increase in allergic incidents as well as if post SARS-CoV-2 infected patients are unable to exercise or have functional limitations.
