President Biden tested negative for COVID-19 on Saturday, according to a letter from White House physician Dr. Kevin O'Connor, but he will continue to isolate until he tests negative a second time.

Axar.az reports that "the President continues to feel very well," O'Connor wrote

The president first tested positive for the virus on July 21. The administration said he experienced only mild symptoms, including fatigue, a runny nose, and cough.

Biden, who is fully vaccinated and twice boosted, was prescribed the antiviral therapy Paxlovid, a standard course of treatment for people who are considered to be at higher risk of adverse affects of COVID, including anyone over 50.
