The president’s antigen test came back positive late Saturday morning, White House physician Dr. Kevin O’Connor said.
“This happens with a small minority of folks,” he wrote. “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.”
Biden reemerged from the White House residence for the first time on Wednesday after working for five days in isolation following his first positive test on July 21.
In a speech delivered from the Rose Garden, Biden praised vaccines and therapeutics as the keys to his mild case of the virus.
His symptoms included a runny nose, cough, sore throat, a slight fever and body aches. He took the standard five-day course of Paxlovid, and also used Tylenol and an albuterol inhaler as needed.
