Another Mainer has died as health officials on Tuesday reported 18 new coronavirus cases in the state.

Tuesday’s report brings the total number of coronavirus cases in Maine to 4,918. Of those, 4,415 have been confirmed positive, while 503 were classified as “probable cases,” according to the Maine Center for Disease Control and Prevention.

The agency revised Monday’s cumulative total to 4,900 down from 4,903, meaning there was an increase of 15 over the previous day’s report, state data show. As the Maine CDC continues to investigate previously reported cases, some are determined to have not been the coronavirus, or coronavirus cases not involving Mainers. Those are removed from the state’s cumulative total.

The latest death involved a Somerset County resident, bringing the statewide death toll to 137. Details about that case weren’t immediately available. Nearly all deaths have been in Mainers over age 60.

New cases were reported in Androscoggin (1), Aroostook (1), Cumberland (1), Oxford (5) and York (8) counties, state data show. Information about where additional cases were reported wasn’t immediately available.

RSU 56’s superintendent, Pam Doyen, said in a Tuesday letter that the district’s schools would close until at least Sept. 29 after “more than one individual” contracted the coronavirus. The district encompasses Carthage in Androscoggin County and the Oxford County towns of Canton, Dixfield and Peru.

The closure comes as Region 9 School of Applied Technology in Mexico, also in Oxford County, reported two coronavirus cases and moved its classes to remote learning for the next two weeks.

University of Maine System spokesperson Dan Demeritt said Tuesday that two University of Maine students were released from isolation, bringing the total number of active coronavirus cases within the university system to zero. There have been 13 reported cases within the university system.

So far, 432 Mainers have been hospitalized at some point with COVID-19, the illness caused by the coronavirus. Of those, 10 people are currently hospitalized, with five in critical care.

Meanwhile, 43 more people have recovered from the coronavirus, bringing total recoveries to 4,280. That means there are 501 active confirmed and “probable” cases in the state, which is down from 530 on Monday.

A majority of the cases — 2,818— have been in Mainers under age 50, while more cases have been reported in women than men, according to the Maine CDC.

As of Tuesday, there have been 339,099 negative test results out of 346,006 overall. About 1.7 percent of all tests have come back positive, Maine CDC data show.

The coronavirus has hit hardest in Cumberland County, where 2,257 cases have been reported and where the bulk of virus deaths — 70 — have been concentrated. It is one of four counties — the others are Androscoggin, Penobscot and York, with 653, 251 and 1,005 cases, respectively — where “community transmission” has been confirmed, according to the Maine CDC.

There are two criteria for establishing community transmission: at least 10 confirmed cases and that at least 25 percent of those are not connected to either known cases or travel. That second condition has not yet been “satisfied” in other counties.

Other cases have been reported in Aroostook (42), Franklin (53), Hancock (53), Kennebec (200), Knox (33), Lincoln (39), Oxford (89), Piscataquis (8), Sagadahoc (62), Somerset (85), Waldo (73) and Washington (15) counties.

As of Tuesday morning, the coronavirus had sickened 6,563,903 people in all 50 states, the District of Columbia, Puerto Rico, Guam, the Northern Mariana Islands and the U.S. Virgin Islands, as well as caused 194,863 deaths, according to Johns Hopkins University of Medicine.
