The number of communities with the highest risk of COVID-19 transmission has again increased, this time to nearly double as many as last week.

Newly released state data shows 55 cities and towns in the red zone this week, compared to the 32 communities on the list last week. The number of communities with the highest risk has been on the rise over the last few weeks, with 20 communities on the list the week before.

The state’s average daily case count has also increased again. This week its average daily case count is  25.6 per 100,000 for the past two weeks. Last week it was 21.5 per 100,000 residents; the week before that it was 19.5 per 100,000 residents.


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 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 10 or more cases per 100,000 residents and a positivity rate of 4 percent or higher.
