Emerging evidence from clinical and laboratory studies has shown that cloth face coverings reduce the spray of respiratory droplets when worn properly, which can help prevent people who have COVID-19 from spreading the virus to others. To help slow the spread of the coronavirus, the Centers for Disease Control and Prevention recommends that people wear face coverings in public and when around people outside their household, especially in circumstances where other social distancing measures are difficult to maintain.

See which of the 50 most populous U.S. cities — in order from least populated to most — have mask mandates in place, and which are charging fines for noncompliance.
