The Centers for Disease Control and Prevention is changing course on some mask guidelines. The agency announced Tuesday that even vaccinated people should return to wearing masks indoors in parts of the U.S. where the coronavirus is surging. The recommendations cited new information about the ability of the delta variant to spread among vaccinated people. The CDC also recommended indoor masks for all teachers, staff, students and visitors at schools nationwide, regardless of vaccination status. In other developments, President Joe Biden said his administration is considering requiring all federal workers to get vaccinated. He dismissed concerns that the new masking guidance could invite confusion.
