The 71-year-old wife of the president tested negative Monday but developed “cold-like symptoms late in the evening,” her communications director Elizabeth Alexander said in a statement.

Alexander said a subsequent rapid antigen test was negative, but a more detailed PCR test was positive.

The first lady has been prescribed a course of the oral antiviral pill Paxlovid and will isolate for at least five days.

She “is double-vaccinated, twice boosted, and only experiencing mild symptoms,” Alexander added.

Jill Biden tested positive while on holiday in South Carolina, where she is staying at a private residence, and will return to the White House after two consecutive negative tests, her aide said.

President Biden, who turns 80 in November, has recently recovered from two separate bouts of the coronavirus.

He first tested positive on July 21 and continued to carry out his duties while isolating at the White House.

After four days of negative tests, he again received a positive result on July 30 and entered isolation a second time.

The White House say she officially resumed on Tuesday, September 7.

‘There are some things you just can’t replace, and I can’t wait to get back in the classroom,’ Biden, 70, told Good Housekeeping magazine in a recent interview.

The first lady has said that teaching ‘isn’t just what I do, it’s who I am.

Biden taught English and writing remotely for months before returning to the classroom.

She taught at the community college throughout the eight years that her husband Joe Biden served as vice president. Leaders of the National Education Association, which is the country’s largest teachers’ union, reacting to Biden’s decision said.

‘She sees it up close and personally and now, in the position as the first lady, not only does she give voice to that from a place of understanding, she has an opportunity to create a platform and to have influence,’ said the union’s president Becky Pringle.

Even though Biden is the first wife of a president to leave the White House for a full-time job she is not the first wife of a president with a teaching background.

Laura Bush, the wife of former President George W Bush, was an elementary school teacher and a librarian but stopped working after having children and was not in the workforce when her husband entered the White House.

Former first ladies Michelle Obama and Hillary Clinton were also working mothers but ended their jobs while at the White House.
