In a memo, Biden’s physician, Dr. Kevin O’Connor, said the president is experiencing no new symptoms and ‘continues to feel quite well.’
O’Connor had warned of the possibility of a testing ‘rebound,’ which can occur on a small percentage of patients who, like Biden, used the antiviral medication Paxlovid as part of their treatment against COVID.
On Saturday afternoon, Bident, 79, tweeted: ‘Folks, today I tested positive for COVID again. This happens with a small minority of folks.
‘I’ve got no symptoms but I am going to isolate for the safety of everyone around me.
‘I’m still at work, and will be back on the road soon.’
President Joe Biden has tested positive for COVID-19, sending him back into isolation just days after he was cleared. Pictured: Biden out of isolation on Thursday after testing negative for a third-day in a row
