The CDC is expected to loosen its indoor masking guidelines to states soon, according to several people familiar with the matter. The agency’s update could come as early as next week. Dr. Rochelle Walensky, the director of the CDC, is expected to discuss masking guidance Wednesday at a White House Covid-19 Response Team briefing. Nothing has been finalized yet, but the CDC is considering a new benchmark for whether masks are needed, basing it on the level of severe disease and hospitalizations in a given community, two people familiar with the situation said.
