BOSTON (WBZ NewsRadio) — New data from the Centers for Disease Control and Prevention has revealed that 12 out of the 14 counties in Massachusetts are now at high or substantial risk of COVID-19 transmission.
The only two counties still at a moderate risk are Franklin and Hampshire Counties.
Last week, the CDC issued new guidance that said fully-people should wear masks in public indoor settings in areas of substantial or high transmission risk. This came amid concerns about the spread of the Delta variant.
The agency said fully-vaccinated people who are immunocompromised, of if someone in their household is immunocompromised, should wear a mask in public indoor settings regardless of level of transmission risk.
Fully-vaccinated people who come in close contact with someone with suspected or confirmed COVID-19 should be tested, and wear a mask in public indoor settings for 14 days or until they receive a negative test.
The CDC has also recommended that all teachers, staff, students, and visitors to schools should wear masks indoors regardless of vaccination status.
