This week, 40 communities in Massachusetts have the highest risk of COVID-19 infection, 17 more than last week, according to state data.
And a new community tops the list for the highest average daily case count per 100,000: Middleton.
But Middleton’s overall case count includes those from the Middleton Jail and House of Correction, where there’s been an outbreak among inmates and employees.
On Monday, Essex County Sheriff Kevin Coppinger said in a video message that the majority of cases have been asymptomatic among inmates. He said all 889 inmates, along with 401 employees and vendors at the facility, were tested last weekend. From those, 137 inmates and 31 employees tested positive.
To be considered high risk, a community has to have an average daily case count greater than 8 per 100,000 residents for the last two weeks. Most cities and towns are color-coded gray – less than 5 reported cases within the last two weeks – or green, which is less than 4 cases per 100,000 residents on average per day for the same period. Communities in yellow had an average daily incidence rate of between 4 and 8 per 100,000 for the last 14 days.
