Face masks provide a simple barrier to help stop the spread of bacteria into the air and other people. The CDC calls this source control. Based on what they know and recent evidence from several academic studies, face masks can significantly reduce the spread of COVID 19.
Those caring for someone who is sick with COVID-19 at home or in a non-healthcare setting may also wear a cloth face covering. However, the protective effects—how well the cloth face-covering protects healthy people from breathing in the virus—are unknown. To prevent getting sick, caregivers should also continue to practice everyday preventive actions: avoid close contact as much as possible, clean hands often; avoid touching your eyes, nose, and mouth with unwashed hands; and frequently clean and disinfect surfaces.
