Commonwealth of Massachusetts Updates Mask Advisory for Vaccinated and Unvaccinated Residents

Please note: The City of Cambridge Emergency Order Requiring Use of Face Masks in Indoor Public Places, effective September 3, 2021, remains in place and requires that face masks or coverings be worn in indoor public places. It applies to everyone over the age of two years old, with exceptions in alignment with the Centers for Disease Control and Prevention and the Massachusetts Department of Public Health guidelines.

Effective December 21, 2021: In response to the spread of the Delta variant and the emerging Omicron variant, the Department of Public Health now advises that all residents, regardless of vaccination status, wear a mask or face covering when indoors (and not in your own home). The DPH particularly urges this recommendation if you have a weakened immune system, or if you are at increased risk for severe disease because of your age or an underlying medical condition, or if someone in your household has a weakened immune system, is at increased risk for severe disease, or is unvaccinated.
