U.S. President Joe Biden continues to test positive for COVID-19, but he feels well and remains fever-free, according to a statement from his physician, Dr. Kevin O’Connor.

O’Connor said in a statement that Biden enjoyed a light workout prior to his Wednesday morning exam. He added that the president is dealing with an occasional cough, but not as frequently as the previous day. Biden’s temperature, blood pressure, pulse, respiratory rate, and oxygen saturation remain normal and his lungs are still clear.

The U.S. president will continue to remain in strict isolation as he recovers from this rebound case, which was detected July 30.

The White House says despite testing positive for COVID-19, Biden continues to work from his executive residence. He also continues to be cautious to protect any staff of the Executive Residence, Secret Service, or White House whose jobs require them to be close in proximity to him.

Biden tested positive for COVID-19 for the first time in late July and was cleared from isolation July 27.

Since testing positive again, Biden has canceled a trip to Michigan and one to his home in Delaware. On the evening of August 1, he addressed a small pool of reporters from a distance on the killing of al-Qaida leader Ayman al-Zawahiri.
