Dr. Fauci is worried that Super Bowl parties will become super spreader events, and recommended just celebrating with family instead of a big group of friends you haven’t seen in a while.

“You don’t want parties with people that you haven’t had much contact with, you just don’t know if they’re infected,” he told Good Morning America. “So as difficult as that is, at least this time around, just lay low and cool it.”

“Every time we do have something like this, there always is a spike,” he said, adding that “now is not the time” for mixed-household gatherings.
