CDC and NIH launch community COVID-19 testing initiative The Centers for Disease Control and Prevention (CDC), in collaboration with the National Institutes of Health (NIH), has launched an innovative community health initiative called "Say Yes! COVID Test" starting in Pitt County, North Carolina, and coming soon to Chattanooga/Hamilton County Tennessee. As many as 160,000 residents across the two communities will have access to free, rapid antigen tests that they can administer themselves to use three times a week for one month. NIH will provide the tests (also called a home-test or at-home test) and evaluate the effectiveness of the initiative, which aims to determine if frequent self-administered COVID-19 testing helps residents reduce community transmission of SARS-CoV-2, the virus that causes COVID-19 disease.
