The Centers for Disease Control and Prevention is expected to backpedal on some of its masking guidelines and recommend that even vaccinated people wear masks indoors in parts of the U.S. where the coronavirus is surging. That’s according to a federal official who spoke to The Associated Press. The CDC is expected to make an announcement Tuesday. The new guidance follows recent decisions in Los Angeles and St. Louis to revert to indoor mask mandates amid a spike in COVID-19 cases and hospitalizations that have been especially bad in the South. The country is averaging more than 57,000 cases a day and 24,000 COVID-19 hospitalizations.
