Wearing Masks Indoors Again? Some States Are a Vehement No.

After the C.D.C. advised masking indoors in areas with high rates of Covid-19, some locales went back under mask mandates. But there was also defiance and hostility.

MIAMI — Even before the Centers for Disease Control and Prevention recommended this week that vaccinated Americans in coronavirus hot spots around the country go back to wearing face coverings indoors, a resistance had been building against any new masking requirements, no matter the resurgence of infections. Hours before the C.D.C.’s announcement on Tuesday, the school board in Broward County, Fla., postponed a meeting on back-to-school protection rules after a small crowd of mask-less adults and children showed up to the lobby of the school district headquarters and got into a tense exchange with masked members of the local teachers’ union. In Missouri, where rampant Covid-19 has once again flooded hospitals, St. Louis County reinstated a mask mandate on Monday, ahead of the C.D.C.’s updated advice — only to face a lawsuit hours later from Eric Schmitt, the state’s Republican attorney general, who accused the county of “unacceptable and unconstitutional” overreach.
