(CNN) President Joe Biden tested positive for Covid-19 again Saturday morning, per a letter from presidential physician Dr. Kevin O’Connor, in what is likely a “rebound” Covid-19 positivity that the doctor noted is “observed in a small percentage of patients treated with Paxlovid.”
Biden has experienced “no reemergence of symptoms, and continues to feel quite well” and will, as a result, not resume treatment, the White House said. O’Connor said the President tested negative on Tuesday evening, Wednesday morning, Thursday morning and Friday morning before testing positive on Saturday morning.
“However, given his positive antigen test, he will reinitiate strict isolation procedures,” the doctor noted. Biden ceased isolating on Wednesday after testing negative on successive antigen tests, celebrating his return in remarks from the White House Rose Garden.
Biden’s physician said the President is not experiencing any symptoms but that he will isolate at the White House. He canceled plans to travel to his home in Delaware Sunday and to Michigan, where he was expected on Tuesday to tout the recently passed bill aimed at boosting US semiconductor production, the White House said Saturday.
“Folks, today I tested positive for COVID again,” Biden wrote on Twitter. “This happens with a small minority of folks. I’ve got no symptoms but I am going to isolate for the safety of everyone around me. I’m still at work, and will be back on the road soon.”
