US President Joe Biden tested positive with coronavirus once again on Saturday after he had first tested positive last week.

The presidential physician Dr. Kevin O'Connor said that Biden is in good health and is likely experiencing a "rebound" COVID-19 positivity that the doctor noted is "observed in a small percentage of patients treated with Paxlovid."

The doctor added that the president experienced "no reemergence of symptoms, and continues to feel quite well" and therefore, he will not resume treatment.

Biden will “reinitiate strict isolation procedures” considering his antigen test came back positive.
