President Biden on Wednesday is continuing to test positive for the coronavirus and therefore will maintain his "strict isolation measures," the White House’s doctor says. 

Kevin O’Connor said in a letter that Biden, who finished a light workout on Wednesday morning, feels well yet is "still experiencing an occasional cough, but less frequently than yesterday." 

"He remains fever-free and in good spirits. His temperature, pulse, blood pressure, respiratory rate and oxygen saturation remain entirely normal," O’Connor added. "His lungs remain clear." 

"Given his rebound positivity which we reported Saturday, we continued daily monitoring. This morning, his SARS-CoV-2 antigen testing remained positive," the doctor also said.
