First lady Jill Biden has tested negative for Covid-19 and will leave South Carolina – where she had isolated since vacationing with Joe Biden – and rejoin the president at their Delaware beach home, her office said Sunday.

The White House announced on Tuesday that the first lady, 71, who like her husband has been twice-vaccinated and twice-boosted with the Pfizer Covid-19 vaccine, had tested positive for the coronavirus. She first had symptoms on Monday.

The president, 79, recovered from a rebound case of the virus on 7 August.

Jill Biden was prescribed the antiviral drug Paxlovid and isolated at the Kiawah Island vacation home for five days before receiving negative results from two consecutive Covid-19 tests, spokesperson Elizabeth Alexander said. Jill Biden planned to travel to Delaware later Sunday.
