The CDC is expected to reinstate mask guidelines today that cover even vaccinated people, if they are indoors in a high-transmission area. The expected announcement will also cover teachers, staff, and students in schools -- regardless of vaccination status.
The expected new guidance would reverse the May recommendation from the CDC that vaccinated persons do not need a mask indoors. The updated guidance is a response to the more easily transmitted Delta variant of the virus that has caused a surge of infections nationwide.
Businesses should check local guidance as well, because some cities and counties are reinstating mandatory masking indoors in light of Delta.
