In his weekly clinical update, Dr. Griffin with Vincent Racaniello are distressed by the continuing government shutdown, first locally acquired chikungunya virus infection, President Trump’s suggestion for removing aluminum from vaccines, H5N1 isolation from backyard birds and turkey farms, and the suggestion of establishing an alternative to the CDC’s MMWR and asymptomatic measles infections before Dr. Griffin deep dives into recent statistics on the measles epidemic, RSV, influenza and SARS-CoV-2 infections, the Wasterwater Scan dashboard, Johns Hopkins measles tracker, the quarantining in the US due to measles, access to anti-influenza antiviral, where to find PEMGARDA, how to access and pay for Paxlovid, can you be retreated with Paxlovid, long COVID treatment center, where to go for answers to your long COVID questions, if colchicine is effective for long COVID, and contacting your federal government representative to stop the assault on science and biomedical research.
