Washington: US President Joe Biden said he was "doing well" in a video posted from his Twitter account after he tested positive for COVID-19 on Thursday.
In the 21-second clip, he also added he was "getting a lot of work done" and would continue with his duties.
White House Press Secretary Karine Jean-Pierre said that Biden was experiencing "mild symptoms" and has begun taking Paxlovid, an antiviral drug designed to reduce the severity of the disease.
She said Biden "will isolate at the White House and will continue to carry out all of his duties fully during that time. He has been in contact with members of the White House staff by phone this morning, and will participate in his planned meetings at the White House this morning via phone and Zoom from the residence."
Biden, 79, is fully vaccinated, after getting two doses of the Pfizer coronavirus vaccine shortly before taking office, a first booster shot in September and an additional dose March 30.
