Four weeks after the coronavirus emerged in Michigan, the number of confirmed cases in the state rose to 18,970 Tuesday and the number of deaths from the illness reached 845.

Included in those numbers supplied by the Michigan Department of Health and Human Services: 118 additional deaths between Monday and Tuesday and 1,749 new cases.

It's the deadliest day yet for coronavirus deaths in Michigan.

“It’s another tough 24 hours,” Gov. Gretchen Whitmer said Tuesday. “We know that we are continuing on what is an upward trajectory at this point in time.”

Whitmer said it is important to remember that the deaths are not just numbers, but that each case represents a person with his or her own story and a family that now can’t mourn in the way they normally would.

“This really is about people,” Whitmer said.

In addition to those who have died, she said it is about “the incredible, hard-working people on the front lines, whether it’s the grocery store clerk putting the food on the shelves or the nurse or the doctor or the respiratory therapist, or the janitor who is sanitizing all these spaces.”

Tuesday marked four weeks since the state's first coronavirus cases were reported on March 10 in Wayne and Macomb counties.

Since then, Michigan — specifically Detroit and Wayne and Oakland counties — has emerged as one of the nation's hot spots for the new coronavirus, which causes the COVID-19 illness.

As of Tuesday, the state had tested more than 43,503 specimens; 27.6% were positive. Because some people may have been tested more than once, the total number of specimens that have tested positive does not equal the total number of people with COVID-19.

Who's getting sick?

Of those with COVID-19, 46% are male and 51% are female, with 3% unknown. Men account for 58% of the state's deaths, according to state data. Not all data adds up to 100%, due to rounding.

By race, African Americans — who count for 14% of the state's population — represent 33% of the state's confirmed cases and 40% of deaths. Caucasians account for 23% of the cases and 29% of deaths.
