Tuesday, Feb. 9, coronavirus data by Michigan county: Cases tallied in 68 of 83 counties

Sixty-eight of Michigan’s 83 counties have seen the number of coronavirus cases drop in the past seven days from the previous week.

The seven-day average of new daily cases is now 1,259 new cases per day, down 25% from an average of 1,547 last Tuesday.

The statewide seven-day average positivity rate is now 4.1% from 5.7% a week ago.

Below is a closer look at county-level data, based on metrics used by the Michigan Department of Heath and Human Services to assess coronavirus risk levels. The scale used by the MDHHS has six levels — “low” plus the AE levels.

First, a look at the seven-day average positivity rates by county, grouped by state metric.

  • Level E (more than 20%): none
  • Level D (15-20%): None.
  • Level C (10-15%): Luce.

The table below lets you search for any county by name to see the seven-day average positivity rate from February 1-7. The graph has been modified to compare the average of the last seven days to the average of the previous week.

New cases per capita

New daily cases per capita is another metric used by the Michigan Department of Health and Human Services to access coronavirus risk.

This measure calculates the average number of new cases per 1 million population.

Tiers for each county:

  • Tier E (over 150 cases per million): 16 counties, highest to lowest — Ontonagon, Missaukee, Lenawee, Manistee, Arenac, Gogebic, Washtenaw, Ingham, Berrien, Saginaw, Calhoun, Cass, Hillsdale, St Joseph, Mecosta and Van Buren.
  • Level D (70 to 149 cases per million): 44 counties — Ottawa, Benzie, Jackson, Lapeer, Livingston, Kent, Branch, Shiawassee, Antrim, Allegan, Midland, Clare, Roscommon, Eaton, Clinton, Wexford, Barry, Grand Traverse, Ionia, Bay, Baraga, Monroe, Kalamazoo, Almost Isle, Leelanau, Mason, Osceola, Wayne, Dickinson, Macomb, Huron, Iron, Newaygo, Oakland, Oscoda, Tuscola, Sanilac, Kalkaska, Gratiot, Houghton, Isabella, Genesee , Muskegon and Gladwin.
  • Level C (40 to 69 cases per million): 17 counties — Otsego, Montmorency, St. Clair, Alpena, Lake, Montcalm, Cheboygan, Emmet, Alcona, Charlevoix, Schoolcraft, Menominee, Oceana, Ogemaw, Algiers, Iosco and Crawford .
  • Level B (20 to 40 cases per million): Delta, Chippewa, Marquette and Luce.
  • Level A (7 to 20 cases per million): None.
  • Low (less than 7 cases per million): Keweenaw and Mackinac.

Here is 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 per capita number that adjusts for population. The arrows indicate whether the total number of new cases reported in the past seven days has increased or decreased from the previous seven days.

Current scores are based on new cases reported from February 2-8. The map below is shaded according to the six levels of the state. The arrows indicate whether the total number of new cases reported over the past seven days has increased or decreased compared to January 26-February. 1.

Overall MDHHS score by region

The MDHHS assigned an overall score to each of the MI Start regions in the state, 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 state’s MI Start districts: Region 1 is Detroit Area; Region 2 is Grand Rapids; Region 3, Kalamazoo; Region 4, Saginaw; Region 5, Lansing; Region 6, Traverse City Region 7, Jackson and Region 8, Upper Peninsula.)

Below are online databases that allow readers to search county-level data for each of the past 30 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 30 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.

(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 30 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.

Latest daily report

On Monday, February 8, the state reported 1,769 new coronavirus cases and 11 new deaths.
