US president had been taking Paxlovid, which has reported numerous cases of virus returning once medication is stopped
Joe Biden has tested positive for Covid-19 only days after testing negative and having apparently largely shrugged off an infection with the virus, the White House physician said in a statement.
The president had contracted Covid and apparently recovered. But Biden had been taking the medication Paxlovid, which has reported numerous cases of effectively reducing the viral load of Covid only for it to return once the medication is stopped.
