"After testing negative on Tuesday, just now, the First Lady has tested positive for COVID-19 by antigen testing," Deputy Communications Director Kelsey Donohue said in a statement. "This represents a 'rebound' positivity. The First Lady has experienced no reemergence of symptoms, and will remain in Delaware where she has reinitiated isolation procedures."
Donohue said the White House Medical Unit has conducted contact tracing and close contacts have been notified.
President Joe Biden, three days with his wife at their Rehoboth Beach, Del. vacation home, continues to test negative, the White House said. He also suffered a rebound case earlier this month after an initial recovery from the virus.
Jill Biden first tested positive for the virus on Aug. 15, when she and her husband were vacationing in Kiawah Island, S.C. She isolated in the beach town until she received two negative tests and was cleared to meet the president in Delaware on Sunday.
Jill Biden, 71, like her husband, has been twice-vaccinated and twice-boosted with the Pfizer COVID-19 vaccine. She had been prescribed the antiviral drug Paxlovid, which has proven to be highly effective at preventing serious disease and death among those at highest risk from COVID-19, but a minority of those prescribed the drug have experienced a rebound case of the virus a few days after their initial recovery.
