First lady Jill Biden has tested positive for the coronavirus, her office announced Tuesday.  

The diagnosis comes after her husband, President Joe Biden, recently tested positive for COVID-19 twice.  

"The First Lady is double-vaccinated, twice boosted, and only experiencing mild symptoms," her communications director, Elizabeth Alexander, said in a statement. "She has been prescribed a course of Paxlovid and, following CDC guidance, will isolate from others for at least five days."  

The positive test comes after the 71-year-old "began to develop cold-like symptoms" late Monday night, according to her office.
