According to sources, US Vice President Joe Biden's previous negative coronavirus test resulted in a positive reading on Saturday, extending his isolation.
In a letter, Dr. Kevin O'Connor, the presidential physician, stated that it is likely a "rebound" of COVID-19 positive and that it is "observed in a small percentage of patients treated with Paxlovid."
"In the antigen test conducted on Saturday morning, Biden tested positive once more," according to O'Connor, who added that Biden's test results from Tuesday through Friday were equally "negative."
Biden tweeted, "Folks, today I tested positive for COVID again," "Only a small number of people experience this. Although I have no symptoms, I will isolate myself for the protection of others. I am still at work and will return to the road shortly."
According to White House spokesperson Karine Jean-Pierre, Biden is "asymptomatic, feeling fine, and working in isolation from the Residence to protect others."
