Simple measures such as routine hand washing (soap and water for 20 seconds, or use of a 60% or greater alcohol-based hand sanitizer), avoiding touching your face, and covering your cough or sneeze are helpful at reducing transmission. The CDC also recommends wearing a mask in public settings around people who don’t live in your household and when you can’t stay 6 feet away from others.
