Biden’s COVID-19 symptoms have ‘diminished considerably,’ his doctor says

President Joe Biden's doctor said Sunday that he "continue to improve significantly" after testing positive for COVID-19 last week.

Kevin O'Connor, Biden's physician, wrote in a letter released by the White House that Biden's primary symptom was a sore throat and that his runny nose, cough and body aches had all "diminished considerably."

Biden completed his third day of Paxlovid, a COVID treatment, on Saturday night.

"His pulse, blood pressure, respiratory rate and temperature all remain normal. His oxygen saturation continues to be excellent on room air. His lungs remain clear," O'Connor added in the memo to White House press secretary Karine Jean-Pierre.

Biden tested positive for the coronavirus three days ago. O'Connor wrote Saturday in a memo that he likely had the BA.5 subvariant, which now accounts for the majority of COVID-19 cases in the country and is more resistant to vaccines than prior strains.

The president appeared to contract a relatively minor case of the virus, according to the White House, with his symptoms consistently including a runny nose and a cough. He started experiencing a sore throat and body aches on Saturday.

O'Connor has never said Biden's pulse, blood pressure, respiratory rate or oxygen were outside normal ranges throughout his infection.

In addition to Paxlovid, Biden has been using an albuterol inhaler for a cough, according to O'Connor. He is fully vaccinated and double-boosted.
