Another 31 coronavirus cases have been reported in Maine, health officials said Thursday.

Thursday’s report brings the cumulative total of coronavirus cases across the state to 4,760. Of those, 4,287 have been confirmed positive, while 473 were classified as “probable cases,” according to the Maine Center for Disease Control and Prevention.

The agency revised Wednesday’s cumulative total to 4,729 down from 4,734, meaning there was an increase of 26 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.

New cases were reported in Androscoggin (4), Cumberland (2), Kennebec (1), Penobscot (1), Somerset (4) and York (14) counties, state data show. Information about where additional cases were reported wasn’t immediately available.

No new deaths were reported Thursday, leaving the statewide death toll at 134. Nearly all deaths have been in Mainers over age 60.

So far, 431 Mainers have been hospitalized at some point with COVID-19, the illness caused by the coronavirus. Of those, 11 people are currently hospitalized, with seven in critical care and three on ventilators.

Meanwhile, 18 more people have recovered from the coronavirus, bringing total recoveries to 4,153. That means there are 473 active confirmed and “probable” cases in the state, which is up from 465 on Wednesday.

A majority of the cases — 2,727 — have been in Mainers under age 50, while more cases have been reported in women than men, according to the Maine CDC.

As of Thursday, there have been 316,638 negative test results out of 323,638 overall. About 1.8 percent of all tests have come back positive, Maine CDC data show.

The coronavirus has hit hardest in Cumberland County, where 2,226 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 631, 250 and 939 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 (40), Franklin (53), Hancock (51), Kennebec (199), Knox (33), Lincoln (36), Oxford (75), Piscataquis (8), Sagadahoc (62), Somerset (69), Waldo (72) and Washington (15) counties. Information about where an additional case was reported wasn’t immediately available.

As of Thursday morning, the coronavirus had sickened 6,370,081 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 190,909 deaths, according to Johns Hopkins University of Medicine.
