Actually, apparently his doctor said, per Foxnews:
His "symptoms continue to improve significantly" following his COVID-19 infection last week, the president’s physician said in a written update Sunday".
Biden completed his third full day of Paxlovid, an antiviral drug that helps reduce the chance of severe illness, on Saturday night, said Physician to the President Kevin O’Connor.
"His predominant symptom now is sore throat," O’Connor said. "This is most likely a result of lymphoid activation as his body clears the virus, and it thus encouraging. His rhinorrhea, cough and body aches have diminished considerably."
O’Connor said that while the president’s voice remains "a bit deep," Biden’s pulse, blood pressure, respiratory rate and temperature all remain normal, and he has no shortness of breath. Biden’s oxygen saturation continues to be "excellent" on room air, according to the doctor, and his lungs remain clear.
Maybe that didn't translate into Canadian fearmongering too well but I take it as a good sign.
