On Sunday President Joe Biden’s doctors said his condition is improving since contracting COVID-19 last week and the most severe symptom currently is a sore throat. The 79-year-old’s cough and body aches have diminished and he is not experiencing any shortness of breath. Doctors say the sore throat is most likely a result of lymphoid activation as his body clears the virus. Biden had been running a temperature after the diagnosis but that has returned to normal.
