WASHINGTON (AP) — President Joe Biden says he’s “doing great” after testing positive for COVID-19. The White House said Thursday the 79-year-old Biden is experiencing “very mild symptoms,” including a stuffy nose, fatigue and cough. He’s taking Paxlovid, an antiviral drug designed to reduce the severity of the disease. Biden is fully vaccinated, after getting two doses of the Pfizer coronavirus vaccine shortly before taking office, a first booster shot in September and an additional dose March 30. White House COVID-19 coordinator Dr. Ashish Jha told reporters at a briefing that the president will isolate for five days and can return to his usual activities after a negative test. Biden himself tweeted to the nation, “I’m doing great. Thanks for your concern.”
