In light of President Trump’s positive test, Democratic presidential nominee Joe Biden is expected to get tested for coronavirus this morning, according to a source familiar with his plans.

Earlier this week, President Trump and Biden shared the debate stage during the first presidential debate. The candidates did not shake hands with each other and did not shake hands with the moderator. Biden nor Trump wore masks on stage.

Former vice president and Democratic presidential nominee Joe Biden needs to be tested for Covid-19 after having been on the same stage as President Trump on Tuesday night for the first presidential debate in Cleveland, said CNN’s Chief Medical Correspondent Dr. Sanjay Gupta.

“He does need to be immediately tested. He has come in proximity to someone that has Covid,” Gupta said.

Trump has not revealed any symptoms yet, and a White House statement said he and first lady Melania Trump are “both well.”

But “as you well know, going back to (top aide) Hope Hicks, you can be contagious or more contagious before you develop some of the symptoms — the pre-symptomatic period,” Gupta warned.

Biden and Trump both attended the first presidential debate on Tuesday night, though they stayed on different sides of the stage at their own podiums.

Biden may have been standing far enough from Trump to avoid infection — but “if you are indoors, you could think of the virus like smoke,” Gupta said.

It’s not clear if the two men interacted backstage or behind cameras.
