The Centers for Disease Control and Prevention is standing by its mask guidance, despite more and more states easing recommendations as the wave of omicron cases continues to recede.
The CDC’s current mask guidance says that people who are up to date on their vaccinations (i.e., vaccinated and boosted if eligible) should wear a mask in indoor public settings in any area that has substantial or high transmission. The agency defines substantial transmission as having between 50 to 99.99 new cases per 100,000 people in the past seven days. High transmission is having 100 or more new cases per 100,000 people in the past seven days.
Currently, 99.1 percent of counties in the entire country have high transmission. Thus, per CDC guidance, nearly the entire country should continue to recommend masking indoors.
