President Joe Biden said Thursday that he's tested positive for Covid-19 but will continue to work while in isolation at the White House despite his mild symptoms.

US President Joe Biden is seen in this photo shared to Twitter, after he tested positive for Covid-19 on Thursday, July 21.

Biden assured Americans in a video that he is "doing well" and that his symptoms are still moderate.

It's gonna be OK," Biden, who was unmasked while standing outside on the Truman Balcony, said in the 20-second video

Due to his age, Biden is at an increased risk for a more severe case of Covid-19, although the CDC says older adults being fully vaccinated significantly reduces their risk of hospitalization.
