U.S. President Joe Biden tested positive for COVID-19 again Saturday, slightly more than three days after he was cleared to exit coronavirus isolation, the White House said, in a rare case of “rebound” following treatment with an anti-viral drug.
White House physician Dr. Kevin O’Connor said in a letter that Biden “has experienced no re-emergence of symptoms, and continues to feel quite well.”
In accordance with Centers for Disease Control and Prevention guidelines, Biden will re-enter isolation for least five days. The agency says most rebound cases remain mild and that severe disease during that period has not been reported.
Word of Biden’s positive test came just two hours after the White House announced a presidential visit to Michigan this coming Tuesday to highlight the passage of a bill to promote domestic high-tech manufacturing. Biden had also been scheduled to visit his home in Wilmington, Del., on Sunday morning, where first lady Jill Biden has been staying while the president was positive. Both trips have been cancelled as Biden has returned to isolation.
Biden, 79, was treated with the anti-viral drug Paxlovid, and tested negative for the virus on Tuesday and Wednesday. He was then cleared to leave isolation while wearing a mask indoors. His positive tests puts him among the minority of those prescribed the drug to experience a rebound case of the virus.
