(WASHINGTON)—First lady Jill Biden has tested positive for COVID-19 again in an apparent case of a “rebound” after initially testing negative for the virus over the weekend.
President Joe Biden, three days with his wife at their vacation home in Rehoboth Beach, Del., continues to test negative, the White House said. He also suffered a rebound case earlier this month after initially recovering from the virus.
Jill Biden first tested positive for the virus on August 15 when she and her husband were on vacation in Kiawah Island, South Carolina. She isolated herself in the beach town until she received two negative tests and was cleared to meet the president in Delaware on Sunday.
Biden’s deputy communications director, Kelsey Donohue, said she “has not had a recurrence of symptoms and will remain in Delaware, where she has resumed isolation procedures.” She added: “The White House Medical Unit has conducted contact tracing and close contacts have been notified.”
71-year-old Jill Biden, like her husband, was twice vaccinated and twice boosted with the Pfizer vaccine against COVID-19. She was prescribed the antiviral drug Paxlovid, which has been shown to be highly effective in preventing serious illness and death among people at highest risk of COVID-19, but a minority of those prescribed the drug had a rebound case of the virus several days after their initial recovery.
The White House said the president is considered a close contact and will wear a mask “for 10 days when indoors and in close proximity to others” in accordance with Centers for Disease Control and Prevention guidelines. The White House will also increase the frequency of its testing for COVID-19.
