The CDC on Friday issued its strongest mask guidance yet during the COVID-19 pandemic, calling for "universal mask wearing" in all activity outside of one's home … "Compelling evidence now supports the benefits of cloth face masks for both source control (to protect others) and, to a lesser extent, protection of the wearer," the report states. … The new guidance lists "universal wearing of face masks" as the first recommendation to help stop the spread of the disease. It says masks should be worn for all indoor activity outside of an individual's home, as well as during all outdoor activity when at least 6 feet of social distancing can't be maintained.
