March 10. The U.S. Centers for Disease Control and Prevention (CDC) late on Thursday said some 98% of the U.S. population live in locations where COVID-19 levels are low enough that people do not need to wear masks indoors.
The CDC on Feb. 25 dramatically eased its COVID-19 guidelines for when Americans should wear masks indoors, saying they could drop them in counties experiencing what it described as low or medium COVID-19 levels.
Last month, the CDC initially said 70% of counties covering 72% of Americans could drop masks. The latest update says 98% of Americans who live in 94% of U.S. counties can ditch masks.
