Biden, 79, tested positive for COVID-19 on Thursday morning after feeling under the weather the night before. As the oldest president in U.S. history, his diagnosis came with some concern. Fortunately Biden was double-vaccinated and twice boosted, and his symptoms were reported as mild from the beginning. Dr. Kevin O'Connor, the president's physician, quickly began treating Biden with Paxlovid, and after five full days of isolating, he is now cleared to re-enter the world — with a mask. What to Know About Paxlovid, the Antiviral Drug That President Biden Is Taking for COVID On Wednesday morning, O'Connor delivered a letter to Biden's team informing them of the president's improvement. "Yesterday evening, and then again, this morning, he tested negative for the SARS-CoV-2 virus by antigen testing," he wrote. O'Connor said that Biden "remains fever-free" and has not needed to take Tylenol for more than 36 hours, adding: "His symptoms have been steadily improving, and are almost completely resolved."

For 10 days, Biden will continue wearing a "well-fitting" mask any time he is around other people. "Acknowledging the potential for so-called 'rebound' COVID positivity observed in a small percentage of patients treated with Paxlovid," O'Connor wrote, "the President will increase his testing cadence, both to protect people around him and to assure early detection of any return of viral replication."
