A spokesperson announced Monday that U.S. first lady Jill Biden tested negative for COVID-19 after a rebound case and will return to Washington, D.C., on Tuesday.
The first lady tested positive for a rebound case last week after testing positive on Aug. 15 during a vacation in Kiawah Island, South Carolina. She reported experiencing "cold-like symptoms" at one point.
The first lady was instructed to isolate after testing positive for a rebound case of COVID-19.
When Mrs. Biden initially tested positive for the virus in mid-August, she was treated with Paxlovid, an antiviral medication.
A spokesperson for Mrs. Biden said she tested negative twice before that. However, upon re-testing, she received a positive result.
The first lady's spokesperson said she had not experienced a reemergence of symptoms but would isolate herself in Delaware as a precaution.
President Joe Biden also suffered a case of rebound COVID-19 after initially testing positive in late July.
According to a study by the National Institutes of Health, up to 5% of people given Paxlovid suffered a rebound infection.
