Nearly 300 more people tested positive for the novel coronavirus between Sunday and Monday, bringing the statewide total to 1,328 cases, according to a state health department update. 

Fifteen people have died after being diagnosed with the virus, according to the state. Chippewa County registered the Upper Peninsula's first COVID-19 case. Eight deaths were of Wayne County residents, four in Oakland County, two in Macomb County and one in Kent County.

The new numbers come as Gov. Gretchen Whitmer on Monday issued a stay-at-home order, closing non-essential businesses and prohibiting people from leaving home except for outdoor activities, to care for family members, or to purchase needed supplies such as groceries or medicine. 

Nearly 86% of the total cases are located in the Metro Detroit counties of Oakland, Macomb and Wayne.

Thirty-six or over 40% of Michigan's 83 counties now have confirmed cases of COVID-19, with Kalamazoo, Muskegon, Newaygo and Chippewa counties reporting their first cases. 

A week ago Monday, 12 counties had confirmed cases. 

Half of the cases involve men and half involve women. More than three-quarters of the cases or 76% involve individuals over the age of 40. 

The state did not provide data about the overall number of people tested in Michigan, or report the number of people who had tested positive and were later hospitalized. 

As of Monday morning, Michigan ranked ninth in the world for provinces or states with confirmed cases, according to Johns Hopkins University and Medicine's Coronavirus Resource Center.

Hubei, China, where the outbreak originated, ranked first with 67,800 cases and New York second with 20,875 cases. 

Wayne County, as of Monday morning, ranked 10th in confirmed cases by U.S. county at 477 confirmed. New York City ranked first with 10,764 confirmed cases. 

The numbers and rankings gathered by Johns Hopkins reflected data the state released early Monday morning. The numbers increased by about 100 by Monday afternoon.

Oakland County Executive David Coulter said Monday the county has 335 confirmed COVID-19 cases, 70 of whom are hospitalized and four of whom have died. The youngest individual diagnosed in the county is 14 days old. 

In neighboring Macomb County, the youngest patient is a month old.
