Biden Tests Negative for Coronavirus but Will Keep Isolating

WASHINGTON — President Biden finally tested negative for the coronavirus on Saturday, a week after his rebound case emerged, but the White House physician said the president would remain in isolation “in an abundance of caution” until a second negative test.

Mr. Biden has been staying away from the Oval Office since he tested positive again on July 30, even as he tried to maintain a public presence through video feeds from the White House residence. The recurrence of the virus has kept him off the road for political events and delayed summer vacation trips as well.

The president experienced few symptoms during his rebound case, according to Dr. Kevin C. O’Connor, the White House physician, and he appeared in relatively good health in his video events over the last few days. “The president continues to feel very well,” Dr. O’Connor said in a memo released to reporters on Saturday.
