The number of COVID-19 cases in Marinette County jumped Monday from 16 to 21, according to Wisconsin health officials.

Fincantieri Marinette Marine in Marinette, Wis., revised its online report to add a new COVID-19 case from Saturday, an employee who last worked Tuesday, May 5. It also had its first positive Friday at Fincantieri Bay Shipbuilding in Sturgeon Bay in Door County. Its web site Monday, however, posted no new cases.

The company now has reported seven cases at its Marinette facility since the first was confirmed April 23.

No other information has been provided for the origins of the other Marinette County cases, which includes one death.

The Wisconsin Department of Health Services’ COVID-19 data site Monday listed another positive in Forest County as well, bringing its total to four cases after having none until Wednesday.

For other Wisconsin counties in the region, the DHS site Monday showed Florence County with two cases; Iron County, two cases and a death; and Vilas County, four cases.

Statewide, Wisconsin had recorded 10,418 cases of COVID-19 and 409 deaths as of Monday afternoon.

For a second straight day, the Michigan Department of Health and Human Services’ online site Monday had no new COVID-19 cases in the Upper Peninsula, with the tally remaining at 98 cases, including 15 deaths.

The MDHHS listed Luce and Baraga counties with one virus case each; Chippewa and Houghton counties with two cases; Schoolcraft County with four cases; Gogebic County with four cases and a death; Dickinson County with five cases and two deaths; Menominee and Mackinac counties with six cases; Delta County with 14 cases and two deaths; and Marquette County with 51 cases and 10 deaths.

The MDHHS also separately listed prison inmates as positive in Luce and Chippewa counties.

Iron, Keweenaw, Alger and Ontonagon counties have yet to report a COVID-19 case in the Upper Peninsula and are the only counties in Michigan not to have at least one positive coronavirus test.

The Norlite Nursing Center in Marquette on Monday confirmed two new COVID-19 deaths this weekend, a woman and a man, both in their 70s. It brings the number of virus deaths at the facility to eight. Fifteen residents remain under isolation with a positive COVID-19 test, the center stated in a post on its Facebook page.

“None of these residents are displaying the common symptoms at this time, which is both encouraging and frightening, because it reinforces the notion that individuals are shedding the virus asymptomatically,” the facility said.

The MDHHS reported 414 confirmed new COVID-19 cases in the state Monday for a total of 47,552 to date. Michigan had 33 new deaths for 4,584 to date.

Dickinson County Healthcare System on Monday listed three county residents testing positive at its facilities thus far, with two deaths, along with five positives from other counties; those counties were not identified. DCHS has tested 327 people for COVID-19, with eight positive, 295 negative and 24 results still pending. DCHS noted there are several additional sources of testing in Dickinson County. The local Health Department records and reports the results of the county-wide data.
