This Week in Virology

TWiV reviews viruses in the news: Chinese scientist who released the SARS-CoV-2 genome sequence sleeps in the street, a case of measles in Haifa, spread of waterborne infectious diseases in Gaza, interstate spread of avian influenza A(H5N1) in dairy cattle, and an orangutan heals himself with medicinal plants, followed by identification of a cell receptor for parechoviruses, and blockade of necroptosis prevents lung injury in severe influenza.

In his weekly clinical update, Dr. Griffin begins with discussing if the antibiotic neomycin is really a pan-antiviral countermeasure, then reviews the recent statistics on SARS-CoV-2 infection before deep diving into if shedding and the rapid antigen test results correlate, the guidelines for spring administration of COVID vaccines boosters, whether COVID booster associates with the long COVID prevalence, discusses the emergency use application of a pre-exposure prophylactic, revised guidelines for how to treat respiratory viral infection guidelines by the CDC, the caveats for improper use of antibiotics to treat SARS-CoV-2 (a viral 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, if administration of an anti-immunoglobulin E monoclonal antibody can be used for COVID-19 treatment, if inhibiting T-cell activation will reduce secretion and production of inflammatory cytokines including IL-6, if changes in the gut microbiome associate with post -acute COVID-19 syndrome, and the pulmonary and neurologic determinants of long COVID-19 such as the presence of neurofilament light chain in plasma.
