President Joe Biden again tested positive for COVID-19 on Monday due to a “rebound” of “positivity” sparked by the drug Paxlovid, according to his doctor in an update.
Biden, 79, tested positive on Monday morning for the third day in a row, White House physician Kevin O'Connor wrote in a letter (pdf) to press secretary Karine Jean-Pierre. Last week, he returned a negative COVID-19 test as he was taking Paxlovid, which is known to cause a recurrence of symptoms after a negative test.
