Jill Biden has 'rebound' COVID-19 case

First U.S. lady Jill Biden tested positive for the coronavirus again in what her office described as a rebound case, forcing her to isolate once again.

“The first lady has experienced no re-emergence of symptoms and will remain in Delaware where she has reinitiated isolation procedures,” Kelsey Donohue, her deputy communications director, said in a statement. “The White House Medical Unit has conducted contact tracing, and close contacts have been notified.”

After initially testing positive for the virus, both the president and the first lady were prescribed Paxlovid, an antiviral medication that helps lessen the effects of the virus. But the medication can also cause those who take it to test positive and even experience symptoms again after finishing the treatment and testing negative. Donohue described the test result on Wednesday as “a ‘rebound’ positivity.”
