BOSTON (AP) — The number of Massachusetts cities and towns that are considered at high risk for transmission of the coronavirus has grown to 63 from 40 in just one week, according to the state Department of Public Health.

The weekly statewide map released Wednesday is based on data collected from Sept. 27 to Oct. 10, according to the department.

Communities that have had more than 8 cases per 100,000 residents in the last 14 days are considered to be at high risk.

Those include the state's three largest cities of Boston, Worcester and Springfield, but also many smaller communities, including Acushnet, Oxford and Nantucket.

The statewide average daily case rate is 8.7 per 100,000 residents.

Not all the news was bleak. Several communities were downgraded from high risk to moderate risk, while 10 towns went from moderate to low risk, health officials said.

The state's confirmed COVID-19 death toll is now nearly 9,430 and its confirmed caseload is more than 138,000, according to state data released Wednesday.
