Biden tests positive again for COVID-19 | USA TODAY
Kevin O'Connor, physician for the president, said in a letter Sunday that Biden "continues to feel well" but he "not surprisingly" tested positive again Sunday for COVID-19. Biden remains isolated at the White House. Paxlovid is an at-home antiviral therapy for those at higher risk for severe illness from COVID-19. Biden, 79, was at risk because of his age. He has been vaccinated and boosted against the virus.

Biden, who first tested positive for COVID-19 on July 21, tested positive again for COVID-19 Saturday morning after being cleared of the virus. He had tested negative Tuesday, Wednesday, prompting him to end his first isolation period, and again Thursday and Friday.
