In this week’s individual community coronavirus data, Chelsea no longer is at the highest risk in the state. Of the 15 communities designated red due to their average daily case rate, Nantucket now has the highest.

Each week, the state releases individual town and city data on the pandemic. Most Massachusetts communities are color-coded gray – less than five cases reported within the last two weeks. Those designated red have had eight or more cases per 100,000 residents on average per day for the last two weeks. Communities in yellow have between four and eight cases per 100,000 residents on average per day. Those in green have an average daily case rate of less than four per 100,000 residents for the same time period.
