US President Joe Biden is still positive for COVID-19, but continued to "feel well" on Sunday morning, his personal physician said in a letter released by the White House.

The 79-year-old president's antigen test 'unsurprisingly remained positive this morning', wrote Dr Kevin O'Connor, calling it a 'bounce back' of positivity that may occur in people treated with Paxlovid, Pfizer's anti-COVID pill.
“The president continues to feel good,” he added. He continues to apply “strict containment measures”.
Mr. Biden, the oldest president ever elected in the United States, had tested positive on July 21 with “very mild symptoms” and was released from confinement on Wednesday, after testing negative.
But he had tested positive again on Saturday, leading him to return to solitary confinement at the White House. A resumption of treatment was not considered useful.
The president, fully vaccinated and who received two booster doses, "continues to conduct the business of Americans from the residence" presidential, noted Dr. O'Connor.
Paxlovid is an antiviral treatment that works by reducing the ability of the virus to replicate, thus slowing the progression of the disease. It must be taken within the first few days after symptoms appear to be effective.
It is recommended in the United States for people at risk of developing a severe case of the disease, a category into which the American president falls due to his age.
