Biden continues to test positive for COVID in ‘rebound’ case

President Biden once again tested positive for COVID-19 Monday, 10 days after initially contracting the virus, according to a note from the president’s doctor, who added that the commander-in-chief “continues to feel well.” 

Biden, 79, will continue to abide by “strict isolation measures,” Dr. Kevin O’Connor wrote in the letter released by the White House

“The President continues to feel well as he starts his week. Given his rebound positivity which we reported Saturday, we continued daily monitoring,” said O’Connor, who added that the president returned a positive antigen test earlier in the day. 

“He will continue to conduct the business of the American people from the Executive Residence,” the doctor continued. 

“As I have stated previously, the President continues to be very specifically conscientious to protect any of the Executive Residence, White House, Secret Service and other staff whose duties require any (albeit socially distanced) proximity to him.” 

The president — who has received four shots of Pfizer’s coronavirus vaccine — initially tested positive for COVID-19 on July 21, when he began quarantining and started a regimen of the antiviral drug Paxlovid.

After isolating and testing negative for the virus last week, Biden resumed his regular duties while wearing a face covering when in proximity with others. 

On Saturday, Biden tested positive for the coronavirus in what has been described as a “rebound” case. 

O’Connor revealed at the time that a “small percentage” of patients who received Paxlovid have had their symptoms “rebound.”
