Tuesday, October 6, coronavirus data by Michigan county: 3 counties turn orange, 7 remain red

Seven Michigan counties — most of which are in the Upper Peninsula — have seen more than 25 new coronavirus cases per capita per day over the past week.

These counties are most at risk of exposure to COVID-19, based on a metric developed by the Harvard Global Health Initiative to assess coronavirus risk levels. They include Keweenaw, Houghton, Iron, Dickinson, Menominee, Delta and Calhoun, and are marked in red on the map below.

The Harvard Institute metric uses a seven-day average of new cases per 100,000 population to assess coronavirus risk levels. The latest assessment is based on data from September 29 to October 5.

The UP moved one county – Baraga – from a risk level of red to orange on Monday. Meanwhile, Ontonagon County has moved from yellow to orange risk level.

In total, UP has six counties in red, six counties in orange, and three counties in yellow.

In the Lower Peninsula, Calhoun remains the only county coded red, with nearly 26 new cases per day per 100,000 people. That’s a 64% increase from the previous week.

Of the 20 counties coded orange, only Ingham and Branch have seen recent declines in cases.

At the other end of the spectrum, four northern Michigan counties remain in the green zone, according to the Harvard Institute metric. These counties include Leelanau, Cheboygan, Almost Isle and Alpena, which currently have minimal coronavirus transmission.

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 September 29 and October 5 has increased or decreased compared to the previous seven days (September 22-28).

Latest news on coronavirus testing

Eleven counties in Michigan reported a positive test rate of 5% or more from Sept. 28 through Oct. 4, including five counties in UP and six in the Lower Peninsula.

The counties with the highest positive rate were Delta (12.3%), Houghton (9.6%), Iron (9.5%), Dickinson (6.7%) and Mackinac (6.3%). Other counties above 5% include Otsego, Iosco, Macomb, Calhoun, Isabella, and Newaygo.

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

As a state, Michigan averages a daily positive test rate of 3.6%. The World Health Organization says schools can safely reopen if fewer than 5% of coronavirus tests over the past two weeks are positive, but state health officials have said they want see the rate below 3%.

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.
