Health experts say that when someone enters your home who is not a member of your immediate household, they should wear a face covering. Thomas A. Russo, MD, professor of medicine and chief of the Division of Infectious Diseases, says you can probably take off your face covering once the person leaves. “If you’re very vulnerable, want to be very conservative, are nervous about imperfect mask usage, and you’re living in a place that isn’t optimally ventilated, you could consider wearing your mask for 30 minutes after they leave,” he said.
