Biden tests positive for COVID-19 again; returning to isolation



President Biden tested positive for COVID-19 in a "rebound" case on Saturday, according to the White House.


"As described last week, acknowledging the potential for so-called ‘rebound’ COVID positivity observed in a small percentage of patients treated with PAXLOVID the President increased his testing cadence, both to protect people around him and to assure early detection of any return of viral replication," White House Doctor Dr. Kevin O'Connor said.


O'Connor said in the letter that Biden tested negative for COVID-19 on Tuesday evening, Wednesday morning, Thursday morning, and Friday morning, but tested positive on Saturday morning by an antigen test.


The doctor says that the re-infection represents "rebound positivity" and said that Biden has not experienced a reemergence of symptoms, and there's no need to restart treatment. Biden will, however, begin "strict isolation procedures," according to O'Connor.
