Joe Biden is urging Americans to stay home and limit their holiday travel this year amid a surge in the novel coronavirus pandemic.

Biden, who has been declared president-elect by many media outlets, made the remarks on Wednesday during a virtual roundtable with workers impacted by the virus. The former vice president, in particular, spent a portion of the event telling those in attendance that despite there being promising news about a vaccine, it is important to remain cautious for the time being.

“I hope you are listening because, as with all the trouble you’re going through, you can not be traveling during these holidays,” Biden said.
