The state releases a map on a weekly basis that uses coronavirus case counts to show which Massachusetts communities are at high, moderate, and low risk for COVID-19 infection.
The assessment “will be updated on a regular basis going forward,” Governor Charlie Baker announced when he introduced the map on Aug. 11. It outlines each town’s average daily increase in cases per 100,000 people, over the most recent two-week period.
The map and its background data will be included in the Department of Public Health’s weekly public health dashboard, which is published every Wednesday.
The most recent map reflects data collected from Sept. 27-Oct. 10, and features 63 cities and towns in the highest-risk category.
The map includes a color-coded ranking system. Here’s what each color means:
- Red: Indicates municipalities that have more than eight cases per 100,000 people, which, based on a national and global health standard, means the community is at extremely high risk for COVID-19 infection.
- Yellow: Indicates municipalities that have between four and eight cases per 100,000 people, or a moderate level of risk.
- Green: Indicates municipalities that have less than four cases per 100,000 people.
- Gray: The lowest-risk color, which indicates there have been less than five total cases of COVID-19 reported in the last 14-day period.
