The press service clarified that the rapid antigen test again showed a negative result, but the PCR test for coronavirus was positive.

For the first time, US President Joe Biden passed a positive test for coronavirus infection on July 21, while on July 27 the test showed a negative result, and the head of the United States announced a return to full-time work after suffering COVID-19.

A few days later, he again passed a positive test for coronavirus.

On August 7, the second test of the American leader for coronavirus showed a negative result.
