Democratic presidential nominee Joe Biden is scheduled to undergo his COVID-19 testing on Friday.

Following the presidential debate and President Donald Trump testing positive for the coronavirus, Biden is advised to be immediately tested because he has come into contact with a virus carrier.

“He does need to be immediately tested. He has come in proximity to someone that has COVID,” CNN‘s Chief Medical Correspondent Dr. Sanjay Gupta commented.

Gupta mentioned that it is unlikely Biden has the virus from the debate because the two parties were standing more than six feet apart. However, since the debate was held indoor and the nominees did not wear masks, a test is still necessary.

It is unclear whether or not Trump and Biden interacted with each other before going on stage.
