The number of cities and towns considered high-risk for contracting the coronavirus by the state nearly doubled from one week to the next, the latest data shows.

Massachusetts' latest weekly data on the coronavirus pandemic, including the updated community-level risk assessment map, shows 40 communities considered at the highest risk for transmitting COVID-19, 17 more than last week.

The data, from the state Department of Public Health, includes a breakdown of the total number of coronavirus cases in each Massachusetts city and town, as well as the new map and more data.

Cities and towns are colored red on the map if they have more than eight cases per 100,000 people. The number of coronavirus cases are on the rise in communities including Waltham, Middleton, Woburn and Randolph.

Despite the current trend, nearly 90% of the state’s cities and towns have not seen an improvement.

The high-risk communities in Wednesday's report are Acushnet, Amherst, Attleboro, Avon, Boston, Brockton, Chelmsford, Chelsea, Dartmouth, Dracut, Dudley, Everett, Framingham, Haverhill, Holyoke, Hudson, Kingston, Lawrence, Leicester, Lowell, Lynn, Malden, Marlborough, Methuen, Middleton, Nantucket, New Bedford, North Andover, Plymouth, Randolph, Revere, Southborough, Southbridge, Springfield, Sunderland, Waltham, Webster, Winthrop, Woburn and Worcester.

The map shows the number of cases detected on average each day over the last two weeks in each of Massachusetts' communities. More than eight cases per 100,000 translates to a high risk and red shading, between four and eight cases per 100,000 is moderate risk and any less than that is low risk.

There are 40 cities and towns shaded red in this map, a 74% increase compared to last week's map, which included data from Sept. 13 to Sept. 26. There were 23 communities on last week's list from the Massachusetts Department of Public Health.

These 19 communities are new to the list since last week: Acushnet, Amherst, Brockton, Chelmsford, Dartmouth, Dudley, Holyoke, Hudson, Kingston, Leicester, Malden, Plymouth, Randolph, Southborough, Southbridge, Sunderland, Waltham, Webster, and Woburn

These two communities, Holliston and Lynnfield, were removed from the list since last week.

Boston entered the red zone last week, and its average incidence rate rose to 10 coronavirus cases per 100,000 in the latest report.

Mayor Marty Walsh on Wednesday announced that Boston Public Schools would pause their reopening after the city’s coronavirus positivity rate climbed above the 4% cutoff it had previously outlined.

Last week, the city held off entering Step 2 of Phase 3 of Massachusetts' reopening plan because it anticipated entering the red zone.

Massachusetts' updated risk map shows a large increase in cities and towns in the highest risk level.

How Massachusetts Measures Hot Spots

Massachusetts has changed how it has measured coronavirus metrics over time.

The color-coded town-by-town data was introduced in August, and the Baker administration announced that the state would focus its strongest COVID-mitigation efforts on towns in the red category. Communities can only move to Step 2 of Phase 3 of Massachusetts' reopening plan, announced Tuesday, if they are not consistently in the red.

Previously, the positive COVID test rate over the prior 14 days had been the standard for measuring hot spots. The Department of Public Health's weekly report still includes that information, along with other metrics like how many tests are being conducted locally and how many cases have been reported locally.

However, some of Massachusetts' smaller towns have taken issue with being categorized based on cases per capita.

Boston Mayor Marty Walsh said he's holding out hope that students can return to class on schedule this fall, even though the city is nearing Massachusetts' highest risk zone for coronavirus.

They say that, when a town only has a few thousand people, an outbreak in just one household can send it into red, which is determined by 8 cases of COVID-19 per 100,000 residents.

Asked last week why he prefers using cases per capita instead of percent positivity, Gov. Charlie Baker said Tuesday that the latter doesn't take into account that some people get tested repeatedly.

"We have a lot of repeat testers in our data, many of whom are repeating for work-related reasons," Baker said.
