BOSTON (WHDH) – The Massachusetts Department of Public Health released an updated list on Thursday detailing the number of coronavirus cases in cities and towns across the Commonwealth.

In an attempt to guide schools and businesses through the state’s phased reopening plan, the colors were previously based on an area’s average virus rate out of 100,000 people.

However, many communities across the Bay State do not reach the 100,000 resident threshold. This prompted health officials to revamp the color-coding system based on population size and positivity rate.

Just 28 cities and towns now fall in the Department of Public Health’s highest-risk category for COVID-19 transmission under the state’s guidelines, down from the 66 that were reported last week.
