This week, Dr. Griffin dives into a Legionnaires’ outbreak in Harlem and the emergence of the invasive longhorned tick. The discussion also touches on a potential Ebola outbreak in the Congo. Florida's decision to end childhood vaccine mandates raises eyebrows amid rising measles cases. The conversation then shifts to COVID-19, highlighting effective treatments like Paxlovid and the importance of vaccination. Long COVID research is gaining traction, with new clinical studies underway and a push for answers and support for affected individuals.
