Tuesday, Nov. 3, coronavirus data by Michigan county: Cases up 63% statewide in past week

Michigan reported 22,979 new coronavirus cases in the past seven days, a new record and a 63% increase from the 14,101 reported the previous week.

Case increases are occurring statewide:

  • Seventeen Michigan counties now have a seven-day positivity rate of more than 10% on coronavirus diagnostic tests, a benchmark the federal Centers for Disease Control says is problematic. These counties include Macomb, Ottawa, Calhoun, Muskegon, Allegan and Van Buren, among others.
  • The state’s seven-day average positivity rate on coronavirus testing is now 7.5%, down from 5.5% a week ago. This increase is proof that the current surge in cases is not just about increased testing.
  • Seventy-five of Michigan’s 83 counties are now at the highest risk level in the state on the seven-day average for new cases per capita. The only counties not on this list: Wexford, Crawford, Leelanau, Montmorency, Huron, Alpena, Oscoda and Alcona.
  • A total of 1,975 people were hospitalized Monday with COVID-19, up from 1,577 a week ago.
  • Three of the state’s eight MI Start regions — the Grand Rapids and Kalamazoo regions and the Upper Peninsula — are now at Level E, the highest level on the state’s coronavirus risk scale and all five other regions of the state are at level D.

The scale used by the Michigan Department of Health and Human Services has six levels – “low” plus AE levels.

The MDHHS assigns an overall score to the eight regions of the state based on factors such as per capita cases, test positivity rates, number of tests administered, deaths and emergency room visits for COVID-19 symptoms. 19.

This interactive map shows these eight regions and their current scores.

(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, Lansing and Region 8, Upper Peninsula.)

Below, MLive applies state metrics to two specific criteria — per capita case counts and test positivity rates — to each county to help readers track coronavirus transmission in their community.

New cases per capita

Seventy-five counties now have a seven-day average of 150 or more cases per million population, the MDHHS threshold for Level E, its highest risk category. That against 73 counties in Monday morning’s post.

The statewide average is now 329 cases per million population.

Of the eight counties that are not Tier E, Wexford, Crawford, Leelanau, Montmorency, Huron, Alpena and Oscoda are Tier D and Alcona is Tier C.

There are no A or B or “low” level counties.

The map below is shaded according to the six levels of the state. The arrows indicate whether the total number of new cases reported between October 27 and November 27. 2 increased or decreased compared to the previous seven days (October 20-26).

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 Sunday and Monday, the state reported 6,709 new coronavirus cases and 17 new deaths.

The state’s seven-day average is now 3,283 new cases per day, a new high, from an average of 2,014 a week ago.
