After consistently rising for weeks, the number of communities in Massachusetts at the highest risk for COVID-19 transmission has decreased.

This week, 59 communities are in the red zone, compared to 77 last week, according to state data.

An updated map shows where the high-risk communities are.

A color-coded map from the Massachusetts Department of Public Health shows where the highest-risk communities are in red.

A community receives a red-zone designation based on a few factors. Small communities with under 10,000 residents are placed in the red zone if they have more than 25 cases total over the last two weeks, according to the state. For communities between 10,000 and 50,000 people, a red-zone designation is given if the community has 10 or more average daily cases per 100,000 residents and if the positivity rate is greater than or equal to 5 percent. For communities over 50,000, they need a daily average of 10 or more cases per 100,000 residents and a positivity rate of 4 percent or higher.
