“This morning, the president’s SARS-CoV-2 antigen test was negative for the second consecutive day,” presidential physician Kevin O’Connor wrote in a letter Sunday. “He will return safely to public engagement and presidential travel.”
Biden also tested negative for an antigen test on Saturday, but remained in isolation until Sunday morning before departing for Rehoboth Beach, Delaware.
As he left the White House for Rehoboth Beach, the president told reporters he was “feeling good,” saying, “After 18 days, I’m free!”
According to the U.S. Centers for Disease Control and Prevention, “People with recurrence of COVID-19 symptoms or a new positive viral test after testing negative should restart isolation and re-isolate for at least 5 days.”
The CDC issued a health warning to doctors on May 24 advising that Covid-19 symptoms sometimes come back, and that may be how the infection plays out in some people, regardless of whether they’ve been vaccinated or treated with drugs like Paxlovid. The CDC said most rebound cases involve mild illness and there are no reports of severe illness.
Biden is fully vaccinated and has received two booster shots. He received his first two doses of the Pfizer/BioNTech Covid-19 vaccine ahead of his inauguration in January 2021, his first booster in September and his second booster in March.
