A total of 77 Massachusetts communities now have the highest risk of COVID-19 transmission, 14 more than last week, according to new data released on Thursday.

And now the state is also delineating communities with an asterisk that have a higher education institution, long-term care facility, or correctional facility that has had more than 10 confirmed cases within the last two weeks, and if those case counts make up more than 30 percent of the total cases for the city or town where it’s located for the same time period.

As a result, towns in the red zone like Middleton and North Andover are now marked with an asterisk for their respective outbreaks at the Middleton Jail and House of Correction and Merrimack College. Chelmsford and Milton are the other red-zone towns marked with an asterisk this week.

Communities color-coded red have had more than eight cases per 100,000 residents of COVID-19 on average per day over the last two weeks. Communities in yellow have had between four and eight cases per 100,000 residents on average per day over the same period. Communities in green have had less than four cases per 100,000 residents on average per day, and those in gray have had less than five cases total for the last two weeks.
