Monday, October 12, coronavirus data by Michigan county: 7 red counties and 25 orange

The list of Michigan counties with accelerated rates of coronavirus transmission keeps growing.

As of Monday morning, there were 32 counties coded red or orange, based on a metric developed by the Harvard Global Health Initiative to assess coronavirus risk levels. That compares to 25 counties on Friday.

The Harvard Institute metric uses a seven-day average of new cases per 100,000 population. The latest assessment is based on data from October 4-10.

Seven counties are coded red, signifying high levels of coronavirus transmission; 25 are orange, indicating heightened concern.

Fourteen of the 15 counties on the Upper Peninsula are red or orange. Code red counties are Iron, Houghton, Delta, Dickinson, Menominee, Mackinac and Keweenaw. Houghton includes Michigan Tech University and Delta includes Escanaba. The orange counties are Marquette, Gogebic, Ontonagon, Schoolcraft, Luce, Alger and Baraga.

The only UP county not on these lists is Chippewa, which includes Sault Ste. Married.

In the lower peninsula, the orange counties are: Kent, Ottawa, Genesee, Ingham, Kalamazoo, Calhoun, Jackson, Eaton, Ionia, Berrien, Isabella, Clare, Barry, Mecosta, Newaygo, Gratiot, Cass and St. Joseph.

At the other end of the spectrum, two Michigan counties — Alpena and Wexford — are in the green zone Monday morning, according to the Harvard Institute metric. These counties currently have minimal transmission of the coronavirus.

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 4 and October 10 has increased or decreased compared to the previous seven days (September 27-October 3).

Latest news on coronavirus testing

Thirteen Michigan counties have a positive rate of at least 5% in reported coronavirus tests in the past seven days ending Oct. 9. The state averages more than 35,000 tests a day.

Dickinson County had the highest seven-day average at 11.7%, followed by Mackinac (10.7%), Iron (8.2%), Houghton (8%), Delta (7.8%) , Kalamazoo (6.7%), Isabella (6.6%), Luce (6.5%), Genesee (5.7%), Macomb (5.7%), Barry (5.3%), Iosco (5.3%) and Otsego (5.3%).

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

The federal Centers for Disease Control says schools can safely open if fewer than 5% of coronavirus tests over the past week are positive.

Below are online databases that allow readers to search county-level data for each of the past 20 days.

Cases per day it was reported to the state

The first is a graph showing new cases reported to the state each day for the past 20 days. This is based on when a confirmed coronavirus test is reported to the state, which means the patient first fell ill a few days prior.

You can call up a graph for any county and you can hover your cursor over a bar to see the date and number of cases. (As of Sept. 1, the state stopped reporting numbers on Sundays.)

(In a few cases, a county reported a negative (decreasing) number of new daily cases, following retroactive reclassification by the Michigan Department of Health and Human Services. In these cases, we subtracted cases of the previous date and put 0 in the reported date.

The following table below shows new cases in the past 20 days based on symptom onset. In this chart, numbers for the most recent days are incomplete due to the lag between people getting sick and getting a confirmed coronavirus test result, which can take up to a week or more.

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 Saturday, the state reported 1,522 new cases of the novel coronavirus and 15 deaths.

The state’s seven-day average is now 1,024 new cases per day, down from an average of 870 a week ago.

COVID-19 PREVENTION TIPS:

Along with washing your hands regularly and not touching your face, authorities recommend practicing social distancing, assuming anyone can carry the virus.

Health officials say you should stay at least 6 feet away from others and work from home, if possible.

Use disinfectant wipes or disinfectant spray cleaners on frequently touched surfaces in your home (doorknobs, faucets, countertops) and carry hand sanitizer with you when you go to places like stores.

Michigan Governor Gretchen Whitmer also issued executive orders requiring people to wear face coverings over their mouths and noses in crowded indoor and outdoor public spaces. See an explanation of what this means here.
