Evidence for Effectiveness of Cloth Face Coverings
To reduce the spread of COVID-19, CDC recommends that people wear cloth face coverings in public settings when around people outside of their household, especially when other social distancing measures are difficult to maintain.
Recently we began requiring that our volunteers wear face masks. Cloth face coverings are recommended as a simple barrier to help prevent respiratory droplets from traveling into the air and onto other people when the person wearing the cloth face-covering coughs, sneezes, talks, or raises their voice. This is called source control. This recommendation is based on what we know about the role respiratory droplets play in the spread of the virus that causes COVID-19, paired with emerging evidence from clinical and laboratory studies that shows cloth face coverings reduce the spray of droplets when worn over the nose and mouth. COVID-19 spreads mainly among people who are in close contact with one another (within about 6 feet), so the use of cloth face coverings is particularly important in settings where people are close to each other or where social distancing is difficult to maintain.
