Biden tested positive on an antigen test and will isolate in case he is contagious, O’Connor said.
“After testing negative on Tuesday evening, Wednesday morning, Thursday morning and Friday morning, the President tested positive late Saturday morning, by antigen testing,” the publically released doctor’s note said.
But the president is not experiencing symptoms, the letter said. As a result O’Connor said Biden had not been prescribed additional medication.
Presidential trips scheduled this week to Delaware and Michigan have been canceled, the White House said. Biden had hoped to promote funding for high-tech manufacturing in the Great Lake State; it is unclear if he will now attend the event virtually.
“The President has experienced no reemergence of symptoms, and continues to feel quite well,” O’Connor wrote. “This being the case, there is no reason to reinitiate treatment at this time, but we will obviously continue close observation.”
O’Conner added that Biden “continues to be very specifically conscientious to protect” his staff.
Biden last week urged Americans to resume wearing face masks indoors – even as he attended several events unmasked during his three-day period of viral remission.
