Biden, 79, tested positive for COVID-19 for the first time on July 21, 2022. He was suffering from mild symptoms at the time.
After he was confirmed infected again, Biden said that he did not have symptoms of infection with the virus, but that he would self-isolate for the safety of everyone around him.
Biden took tests to detect the virus four times between Tuesday and Friday, and the result was negative at that time.
There is interest in Biden's health, as he is the oldest president in the history of the United States, and he will turn 80 in November 2022.
