Thursday, Oct. 8, coronavirus data by Michigan county: Cases rise in 55 UP-led counties

Fifty-five of Michigan’s 83 counties saw an increase in coronavirus cases over the past week, while 20 counties reported declines and eight remained neutral.

Mackinac, Menominee, Dickinson and Keweenaw counties on the Upper Peninsula are among those that have reported increases and are averaging more than 25 new cases per day per 100,000 people. Houghton, Iron and Delta counties are in decline but also remain at the highest risk level.

No county in the Lower Peninsula is reporting more than 25 new cases per day per capita, which is the worst of four risk levels based on a metric developed by the Harvard Global Health Initiative that looks at new cases per day over a period of a week.

Of the 22 counties coded orange — 10 to 24 new cases per day per 100,000 population — only Calhoun (22.4) exceeds 20 new cases per day, according to data from Oct. 1-7.

On the other side of the spectrum, only Alpena County is coded green, meaning it has less than one new case per day per capita. Northeast County reported no new cases over the past week, down from three cases the previous week.

The map below is shaded by the average number of new cases per day per 100,000 population. The arrows indicate whether the total number of cases between October 1 and October 7 has increased or decreased compared to the previous seven days (September 24-30).

Latest news on coronavirus testing

After processing nearly 244,000 diagnostic tests over the past week, Michigan has averaged a daily positive test rate of 3.2%.

The World Health Organization says schools can safely reopen if fewer than 5% of coronavirus tests in the past two weeks are positive. By that standard, 14 counties should have no schools open, according to data from Sept. 30 to Oct. 6.

Houghton and Delta counties each averaged 11% positivity over the past week, followed by Iron (8.4%), Mackinac (7.8%), Dickinson (7.6%) and Iosco ( 6.1%). Other counties at or above 5% include Algiers, Isabella, Otsego, Calhoun, Macomb, Keweenaw, Genessee, and Kalamazoo.

Counties just below the 5% line include Newaygo (4.9%), Monroe (4.7%), Menominee (4.3%), Cass (4.2%) and Luce (4.2%) ).

Note: The number of positive tests does not correspond to confirmed cases, because the same patient can be tested more than once.

More localized maps

Below are two maps created by the EpiBayes research group at the University of Michigan Department of Epidemiology, which has access to subcounty data collected by the Michigan Department of Health and Human Services.

The interactive maps break the state down into 10 kilometer hexagons to provide a more localized view of where coronavirus cases are occurring. You can click here to access the research project website.

The first map looks at confirmed and probable coronavirus cases over the past week. You can click on a hexagon to see the underlying data.

You can use the triangle button at the top right of the map to switch to the second map, which shows the total number of confirmed coronavirus cases and deaths since the start of the pandemic.

Last daily report
