Although the nation has reached an important milestone in expanding coronavirus vaccine eligibility to all adults, public health experts in Massachusetts warn that the pandemic isn’t over.
The number of Massachusetts communities at the highest risk of coronavirus transmission is down again this week.
The town-by-town coronavirus data released Thursday showed 48 communities in the high-risk red zone, down from 59 last week. It's the second straight week the figure has declined; the most communities in the high risk "red zone" was in mid-January, when there were 229 cities and towns in it.

The town-by-town coronavirus risk data classifies communities' risk level on a scale from red, the highest, to grey, and is one of many metrics tracked by the state that had been showing the latest COVID surge subsiding, though others are also on the rise.

Massachusetts COVID Hot Spots
The following 48 communities are in the highest risk level as of Thursday: Adams, Ayer, Bellingham, Berkley, Brewster, Brockton, Carver, Chicopee, Dennis, Dracut, Edgartown, Fall River, Freetown, Hampden, Harwich, Haverhill, Holyoke, Lawrence, Lowell, Ludlow, Lynn, Methuen, Nantucket, New Bedford, Oak Bluffs, Palmer, Peabody, Plainville, Plymouth, Rehoboth, Revere, Seekonk, Southwick, Springfield, Sterling, Sutton, Swansea, Taunton, Templeton, Tisbury, Townsend, Upton, Wareham, West Boylston, West Bridgewater, Westport, Winchendon and Yarmouth.
Of those communities, nine are newly in red on the list this week: Bellingham, Berkley, Carver, Hampden, Palmer, Peabody, Townsend, Upton and Winchendon.
And 20 communities dropped out of red: Avon, Barnstable, Chelmsford, Dighton, Hamilton, Hanson, Lee, Littleton, Mashpee, Middleborough, Milford, Monson, Orange, Paxton, Saugus, Somerset, Tyngsborough, West Springfield, Whitman and Williamstown.
To qualify for the red, high-risk category under the metrics, communities with populations under 10,000 must have more than 25 cases. For mid-size communities of between 10,000 and 50,000 people, they must have an average of more than 10 cases per 100,000 people and a positive test rate of more than 5%. And for larger communities of greater than 50,000 people, they must have more than 10 cases per 100,000 people and a positive test rate of more than 4%.
Previously, the state used the number of cases detected on average each day over two weeks to determine if Massachusetts' communities are at high risk for coronavirus transmission. The new list factors in population size and positive test rate.
