UNDATED (AP) – Dr. Anthony Fauci is recommending masks at Thanksgiving gatherings if the coronavirus status of people is unknown. The nation’s top infectious disease expert told “CBS This Morning” that “even if it’s a very small group, to the extent possible, keep the mask on.” Fauci says if families have either quarantined or been tested for the coronavirus, it’s not as necessary. But he says it’s wise to take precautions because people without symptoms don’t know they are infected. The U.S. set a single-day record of more than 160,000 coronavirus cases on Thursday. Fauci says if people wear masks and stay socially distant, the numbers will start to come down. He says when a vaccine becomes available, it will help turn things around.
