With COVID-19 cases and other respiratory illnesses rising across the region, some area hospitals have begun to bring back face mask requirements to halt the spread of infections.

Boston Medical Center said Thursday it would resume masking requirements in all patient-care areas beginning Friday. On Monday, the Dana-Farber Cancer Institute reinstated its mask requirements in all clinical and public spaces, and the Beth Israel Lahey Health system (BILH) updated its policies to require masking for all health care personnel upon entry to a patient room or bed space.
