Chief public health officer Derrick Neal said those who test positive for Covid should isolate and wear a mask around others. “Residents can call (617) 933-0797 with questions and to get connected to treatment, masks and tests, and even food and other basic community resources while they isolate,” Neal said.

Mayor Sumbul Siddiqui and City Manager Yi-An Huang said in a joint statement that the city continued “to support our community accessing important tools like rapid antigen tests to keep themselves, their families and our community safe, and we want to thank city staff for making this public distribution effort possible. It is important that residents continue to take precautions to help slow the spread of Covid-19, including getting vaccinated and receiving the most recent Covid-19 booster dose recommended for you by the Centers for Disease Control and Prevention.”
