"President Joe Biden on Saturday tested positive for Covid-19 once again after consecutive days of testing negative for the virus, his physician [Dr. Kevin O'Connor] said."

"O’Connor had previously warned of the potential for a “rebound” in positive test results, a phenomenon among a small percentage of patients who, like Biden, used the antiviral medication Paxlovid as part of their treatment."

"The president first tested positive for Covid on July 21. He felt “mild symptoms” including a dry cough, runny nose and fatigue, O’Connor said at the time. Biden began working in isolation but returned to the Oval Office five days later after testing negative for Covid twice over a 24-hour period."

"The president tested negative for Covid on Tuesday, Wednesday, Thursday and Friday, but tested positive on Saturday morning from an antigen test. “This in fact represents ‘rebound’ positivity,” the doctor wrote."
