US President Joe
Biden tested positive for Covid-19 again on Saturday in what the White House
doctor described as a "rebound" case seen in a small percentage of
patients who take the antiviral drug Paxlovid.
Biden, 79, who emerged from Covid isolation on Wednesday
after testing positive on 21 July, said he was feeling fine.
He will now return to strict isolation and will cancel
planned trips to his home in Wilmington and work trip in Michigan, the White
House said. Biden held public events on Wednesday and Thursday, but none on
Friday.
The forced isolation comes as the White House was hoping to
celebrate some recent legislative victories to help boost Biden's slumping poll
ratings.
Biden had planned the Michigan trip to tout Thursday's
passage of legislation to boost the US semiconductor chips industry.
Biden's positive test is believed to be a
"rebound" experienced by some Covid patients who take the anti-viral
drug Paxlovid, according to White House physician Dr. Kevin O'Connor. Paxlovid
is an antiviral medication from Pfizer Inc (PFE.N) that is used to
treat high-risk patients, such as older patients.
A small but significant percentage of people who take
Paxlovid will suffer a relapse or a rebound that occurs days after the five-day
treatment course has ended, studies have shown.
White House officials had previously suggested a rebound
case of Covid was unlikely, based on reports of cases around the country.
However, Biden continued to be tested and monitored.
Biden tweeted about his positive case, saying it can happen
to a "small minority of folks." He later posted a video on Twitter
where he said he was "feeling fine" and "everything's
good."
A White House official said contact tracing efforts were
underway Saturday after Biden's positive Covid-19 test.
National Institute of Allergy and Infectious Diseases
Director Dr. Anthony Fauci also experienced rebound Covid-19. His symptoms got
worse when they returned after treatment, and his doctors prescribed another
course of Paxlovid.
O'Connor said Biden tested negative for the last four days,
and there is no plan to reinitiate treatment given his lack of symptoms.
Biden previously described his experience with Covid as
mild, saying he was able to continue working while in isolation and attributed
his relative ease with the disease to vaccines and other treatments.
O'Connor had previously said Biden would be tested regularly
to watch for a potential "rebound" Covid-19 case, which can be
experienced by some patients who have been treated with Paxlovid, the drug the
president received.
