Friday, Oct. 9, coronavirus data by Michigan county: 6 counties down one risk level, 1 up

Five counties in Michigan’s Lower Peninsula moved from the second coronavirus risk factor to third on Thursday, Oct. 8, while one in the Upper Peninsula moved up one level.

The four-tier risk assessment is based on a metric developed by the Harvard Global Health Initiative that looks at new cases per day per 100,000 people over a one-week period. The metric uses four colors, with red being the highest risk level and green the lowest.

On Thursday, Allegan, Branch, Iosco, Lenawee and Saginaw counties all went from code orange (10 to 24 new cases per day per capita) to yellow (1 to 9 cases per day). Crawford County also moved from yellow risk level to green (less than 1 case per day).

Meanwhile, in the Upper Peninsula, Gogebic County has turned from yellow to orange with 16.4 new cases per day per 100,000 people. The county borders Wisconsin, a state that is reporting more than 2,400 new cases daily.

In total, Michigan has seven counties coded red, 18 counties coded orange, 56 counties coded yellow, and two counties coded green.

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 2 and October 8 has increased or decreased compared to the previous seven days (September 25 to October 1).

Latest news on coronavirus testing

As a state, Michigan is averaging a positive test rate of 3.2% over the past week.

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, nine counties are not expected to open schools, according to data from Oct. 1 to Oct. 7.

These counties include Houghton (9.3%), Dickinson (8.6%), Delta (8.3%), Iron (7.1%), Iosco (6.2%), Isabella (5.3%) , Kalamazoo (5.3%), Calhoun (5.1%), and Macomb (5.1%).

Eight counties — plus the Michigan Department of Corrections — are reporting less than 1% test positivity over the past week. This includes Alpena, Crawford and Oscoda counties, all of which have had no positive tests in the past seven days.

The map below shows the seven-day average testing rate by county. Again, readers can hover their cursor over a county to see the underlying data. If you don’t see the map, click here.

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

On Tuesday, the health department reported 1,197 new cases of coronavirus and 22 new deaths.

The state’s seven-day average is now 932 cases per day, which is the highest daily average in more than five months. A week earlier, the state averaged 854 cases per day.
