TWiV 1119: Gene editing latent herpes

In his weekly clinical update, Dr. Griffin delves into highly pathogenic H5N1 infection of hunting dogs, dairy cattle, humans and alpacas before reviewing the recent statistics on SARS-CoV-2 infection, risks factors associated with the development of severe COVID-19 in pediatric patients, virus transmission on commercial airline flights, the guidelines for spring administration of COVID vaccines boosters, the emergency use application of a pre-exposure prophylactic, a drug interaction database, absence of durability of XBB.1.15 vaccine induced immunity and 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, and discusses why development of long COVID should be included in the development of treatments for acute viral disease, if vaccination effects long COVID, structural impairment of brain during long COVID, how cognitive and respiratory function may be compromised in long COVID.  For more information about long COVID-19 listen to TWiV 1088 and for H5N1 in dairy cattle and unpasteurized milk TWiV 1117.

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.
