The number of Massachusetts communities at the highest risk for COVID-19 spread has dipped for a second consecutive week.

As of Thursday, 48 communities were in the red zone, down from 59 last week, state data shows.

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

Red-zone designations are based on a variety of factors.

Communities with 10,000 residents or fewer that had more than 25 total cases over the last two weeks are placed in the red zone.

Cities and towns with 10,000 to 50,000 residents must hit a threshold of 10 or more average daily cases per 100,000 residents and their positivity rate must be greater than or equal to 5 percent.

Communities with more than 50,000 residents must have a daily average of 10 or more cases per 100,000 residents and a positivity rate of at least 4 percent.
