Three communities have been added to the state’s list of towns and cities at a high risk for spreading coronavirus.
Analyzing average daily cases from Aug. 2 to Aug. 15, the state said Wednesday that 10 communities at high risk are: South Hadley, Brockton, Winthrop, Saugus, Salem, Revere, Lynn, Lawrence, Everett and Chelsea.
South Hadley, Brockton and Winthrop are new to that designation, shaded red on the map, this week. Last week, the state said high-risk communities were Granby, Holyoke, Chelsea, Everett, Hull, Lawrence, Lynn, Revere, Salem and Saugus.
Hull, Granby and Holyoke are no longer high-risk communities.
The Massachusetts Department of Public Health is basing this designation on new coronavirus cases in a two week period and the average daily cases per 100,000 residents.
In South Hadley, there have been 28 cases counted in the last two weeks with an average daily rate of 11.1 per 100,00 residents.
Brockton saw 117 cases in the last two weeks with an average daily rate of 8.5 per 100,000 residents.
In Winthrop, 30 cases have been detected in the last two weeks with an average daily rate of 11.4 per 100,000 residents.
Chelsea and Lynn had the highest case rates, at 23.9 and 23.6 per 100,000, respectively.
The color-coded map indicates average daily cases per 100,000 residents over a two week period, designating communities as:
- Red: higher risk, more than eight cases per 100,000 residents
- Yellow: moderate risk, four to eight cases 100,000 residents
- Green: lower risk, less than four cases 100,000 residents
Communities with fewer than 5 cases are not given a designation and are unshaded on the map.
The map is updated and shared publicly on Wednesdays. Data on new cases in each community is listed online.
Additionally, state health officials on Wednesday announced 262 new cases of coronavirus and 28 more deaths related to the illness.
