In his weekly clinical update, Daniel Griffin and Vincent Racaniello express concern  about vaccine policy and ACIP, scaling back of the CDC's role in global public health, shingles vaccine and dementia, new screwworm cases, the Ebola outbreak in the Congo and Uganda and where the hantavirus outbreak began, before Dr. Griffin deep dives into the measles outbreak, recent statistics on RSV, influenza and SARS-CoV-2 infections, the Wasterwater Scan dashboard, Johns Hopkins measles tracker, Virgina outbreak of measles, how to access and pay for Paxlovid, how more people were negatively impacted by influenza than COVID, discontinuing contact precautions for COVID, where to go for answers about long COVID-19, and contacting your federal government representative to stop the assault on science and biomedical research.
