Federal officials eased their guidelines on Covid-19 masking, including at schools, in a shift that reflects decreased risks from the Omicron variant, a steep drop in cases and mitigation efforts nationwide.
The Centers for Disease Control and Prevention on Friday changed the metrics it uses to assess Covid-19 risk by county across the U.S. Risk will now be assessed based on three factors, the CDC said: new Covid-19 cases per 100,000 residents in the past seven days; new Covid-19-related hospital admissions; and the percentage of hospital beds occupied by Covid-19 patients.
