First lady Jill Biden has tested positive for COVID-19.

Axar.az informs that the result of a PCR test came back positive after she started experiencing cold-like symptoms late Monday evening. Biden is fully vaccinated, has received two boosters and only has mild symptoms, spokesperson Elizabeth Alexander said in a statement.

She noted the first lady tested negative Monday as part of her regular testing and on a rapid antigen test Tuesday before the PCR result came back positive.

“She has been prescribed a course of Paxlovid and, following CDC guidance, will isolate from others for at least five days,” Alexander said in the statement. “Close contacts of the first lady have been notified.”
