In his weekly clinical update, Dr. Griffin delves highly pathogenic H5N1 biology including its circulation in New York City, being able to infect cells within mammary glands and why testing is not supported before reviewing the recent statistics on SARS-CoV-2 infection, how vaccination reduced deaths and hospitalizations associated with COVID-19 and how to take off PPE to reduce virus transmission, discussing the guidelines for spring administration of COVID vaccines boosters, the emergency use application of a pre-exposure prophylactic, a drug interaction database and the global phase 3 trail of a novel antiviral, continues to dispel the myth of viral rebound, when to use steroids and the benefits of convalescent plasma, what do when healthcare workers succumb to SARS-CoV-2 infection, reminisces about when available monoclonal antibody therapies were effective, and discusses muscle training/exercise for treatment of PASC/long COVID and the use of RNase for its treatment.

In his weekly clinical update, Dr. Griffin delves into discussing drinking “raw” milk possessing H5N1 influenza virus, if the virus can reproduce in the human gut, and the meaning of finding viral RNA in wastewater samples before reviewing the recent statistics on SARS-CoV-2 infection, the guidelines for spring administration of COVID vaccines boosters, withdrawal of AstraZeneca’s SARS-CoV-2 vaccine from the European market, discusses the emergency use application of a pre-exposure prophylactic, continues to dispel the myth of viral rebound, when to use steroids and the benefits of convalescent plasma, what do when healthcare workers succumb to SARS-CoV-2 infection, if administration of colchicine for the management of COVID-19, compares and provides information for the enrollment into the NIH clinical trials of long COVID and its effects on sleep, exercise intolerance and the cognitive profile in multiple sclerosis and post-COVID, exercise intolerance and post-exertional malaise. For more information about cow and milk infection by H5N1 listen to the discussion with Richard Webby on TWiV 1113 and for long COVID-19 listen to TWiV 1088.

In his weekly clinical update, Dr. Griffin deep dives into infections of dairy cattle with high pathogenic influenza H5N1, how long virus has been circulating and if known anti-influenza antivirals can reduce secondary attack rates, before reviewing the recent statistics on SARS-CoV-2 infection, the guidelines for spring administration of COVID vaccines boosters, whether COVID booster takes associates with long COVID prevalence, discusses the emergency use application of a pre-exposure prophylactic, if administration of oral antiviral therapies can prevent the onset of post-acute sequelae following SARS-CoV-2 infection, continues to dispel the myth of viral rebound, when to use steroids and the benefits of convalescent plasma, what do when healthcare workers succumb to SARS-CoV-2 infection, compares and contrasts the cognitive profile in multiple sclerosis and post-COVID, exercise intolerance following SARS-CoV-2 infection and the epidemiology of the pandemic in a Kenyan refugee camp.
