In his weekly clinical update, Dr. Griffin discusses the how the pandemic influenced the healthcare job market and why people conceal their infectious diseases before he reviews most recent statistics on the circulation of respiratory syncytial virus, influenza virus and SARS-CoV-2 virus, including all circulating variants in the US, discusses if susceptibility and disease severity are inheritable traits, if vaccination during pregnancy protects neonates or leads to adverse effects, the effectiveness of a monovalent XBB.1.5 against disease resulting from infection with Omicron variants, whether vaccination in the same or opposite arms effect antibody protection, continues to dispel the myth of viral rebound, how to pay for paxlovid, when to use steroids and the benefits of convalescent plasma, how SARS-CoV-2 infection may alter one's sleep patterns, what the health and economic burdens of mild disease are, and if there are predictors for recovery from fatigue and cognitive deficits following SARS-CoV-2 infection.
