Los Angeles County public health officials are now "strongly" recommending everyone to wear masks in indoor public places, regardless of vaccination status, due to an increased spread of the Delta variant. The recommendation, which officials say is a precautionary measure, is a shift from current guidance, which allows fully vaccinated people to go maskless in most settings. "Public Health strongly recommends people wear masks indoors in settings such as grocery or retail stores; theaters and family entertainment centers, and workplaces when you don't know everyone's vaccination status," L.A. County Department of Public Health said in a statement.
