This Week in Virology

In his weekly clinical update, Daniel Griffin and Vincent Racaniello comment on incidences of locally transmitted malaria in the US, mpox diagnostics, the latest developments surrounding hantavirus infections, and the Ebola outbreak in the Congo and Uganda including vaccine candidates before Dr. Griffin deep dives into the measles outbreak, recent statistics RSV, influenza and SARS-CoV-2 infections, the Wasterwater Scan dashboard, Johns Hopkins measles tracker, the measles outbreak in Texas in 2025, how to access and pay for Paxlovid, where to go for answers about long COVID-19, casual association of auto-antibodies and COVID complications and contacting your federal government representative to stop the assault on science and biomedical research.
