U.S. President Joe Biden continued to test positive for COVID-19 on Tuesday, his physician said in a memo released by the White House.

Biden “continues to feel well, though he is experiencing a bit of a return of a loose cough,” his physician Kevin O’Connor said. “He remains fever-free and in good spirits.”

After having tested negative on Tuesday and Wednesday last week, Biden tested positive for COVID again on Saturday in what O’Connor described as a “rebound” case seen in a small percentage of patients who take the antiviral drug Paxlovid.

FISM News reported that the White House first announced on July 21 that Biden tested positive for COVID, before announcing he’d recovered on July 28, and reporting that he’d tested positive again on July 31.
