So there is good news and bad news in Michigan’s latest coronavirus figures.
The bad news: The number of new coronavirus cases surpassed 50,000 last week, a new record.
The good news: The increase from the previous week was “only” 16%, a sign that exponential growth in numbers may slow.
A good sign, too: the seven-day average coronavirus test positivity rate fell slightly from 13.4% on Friday to 13% this morning.
Below is a more in-depth look at the data at the county level, based on metrics used by the Michigan Department of Health and Human Services to assess coronavirus risk levels. The scale used by MDHHS has six levels – “low” plus AE levels.
First, a week at the seven-day average positivity rates by county, grouped by state metric.
- Level E (over 20%): Six counties, highest to lowest – Chippewa, Dickinson, Muskegon, Hillsdale, Baraga and Berrien.
- Level D (15-20%): 20 counties, highest to lowest – Branch, Oceana, Allegan, Cass, Bay, Macomb, Saginaw, Monroe, Lapeer, Ontonagon, Missaukee, Menominee, Lake, Barry, Newaygo, St Clair, Delta, Gladwin, Tuscola and Genesee.
- Level C (10-15%): 33 counties, highest to lowest – Ottawa, Kent, Van Buren, Gogebic, Crawford, Wexford, Ionia, Roscommon, Oakland, Iosco, Shiawassee, Arenac, Osceola, Midland, Livingston, Wayne, Eaton, St. Joseph, Kalamazoo, Isabella, Oscoda, Marquette, Jackson, Lenawee, Keweenaw, Montcalm, Montmorency, Clinton, Mecosta, Kalkaska, Calhoun, Grand Traverse and Ogemaw.
- Level B (7-10%): 16 counties, from highest to lowest – Ingham, Houghton, Charlevoix, Sanilac, Alcona, Huron, Mason, Iron, Otsego, Gratiot, Cheboygan, Benzie, Antrim, Leelanau, Manistee and Alpena ,
- Level A (3-7%): Seven counties – Clare, Emmet, Washtenaw, Mackinac, Presque Isle, Luce and Algiers.
- Low (less than 3%): Schoolcraft.

New cases per capita
Daily new cases per capita is another metric used by the Michigan Department of Health and Human Services to access coronavirus risk.
In this measure – which calculates the average number of new cases per 1 million population – the 83 counties are all at level E, the highest risk level on the MDHHS scale. The threshold for level E is 150 cases per day per million inhabitants.
Here’s an online database that allows readers to see the number of new coronavirus cases in the past seven days compared to the previous week, as well as the number per capita that is adjusting to the population.

Current scores are based on new cases reported from November 15 to 21. The map below is shaded based on the six levels of state. Arrows indicate whether the total number of new cases reported in the past seven days has increased or decreased from the previous seven days (November 8-14).

Overall MDHHS score by region
MDHHS assigned an overall score to each of the state’s MI Start regions, looking at factors such as new cases and deaths per capita, test positivity rates, number of tests administered, and emergency room visits for symptoms of COVID-19.
As of Nov. 4, Michigan’s eight MI Start regions are at the highest level used by the state to assess coronavirus risk.
This interactive map shows these eight regions and their current scores. You can hover your cursor over a county to see the underlying data.
(The MI Start districts of the state: Region 1 is the Detroit region; region 2 is Grand Rapids; region 3, Kalamazoo; region 4, Saginaw; region 5, Lansing; region 6, Traverse City ; Region 7, Lansing, and Region 8, the Upper Peninsula.)
Below are online databases that allow readers to search county-level data for each of the past 20 days.
Cases daily it was reported to the State
The first is a graph showing new cases reported to the state each day over the past 30 days. This is based on when a confirmed coronavirus test is reported to the state, which means the patient first became ill several days previously.
You can call up a chart for any county, and you can hover your cursor over a bar to see the date and number of cases. (As of September 1, the state stopped reporting numbers on Sundays.)
(In a few cases, a county reported a negative (decline) number of new daily cases, following a retroactive reclassification by the Michigan Department of Health and Human Services. In these cases, we subtracted the cases of the previous date and put 0 in the reported date field.)
The following graph below shows new cases over the past 30 days based on symptom onset. In this graph, the numbers for the most recent days are incomplete due to the delay between illness 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’s Department of Epidemiology, which has access to sub-county data collected by the Michigan Department of Health and Human Services.
The interactive maps break down the state into 10-kilometer hexagons to provide a more localized overview of where coronavirus cases are occurring. You can click here to go to the research project website.
The first map examines confirmed and probable cases of coronavirus 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.
Latest daily report
On Saturday, November 21, the state reported 7,528 new cases of coronavirus and 101 new deaths.
