Monday, November 9, coronavirus data by Michigan county: First week of November cases up 22% from September total

In the first seven days of November, Michigan reported 29,614 coronavirus cases, 22% more than the 24,294 cases reported for the whole month of September.

Meanwhile, 238 coronavirus deaths were reported last week, more than triple the daily average for September.

The number of cases and deaths are also increasing at a much faster rate than in October, when Michigan’s coronavirus numbers really started to rise.

The number of cases increased by 47% in the first week of November compared to the last week of October. The number of deaths increased by 51% last week.

To date, three of the state’s eight MI Start regions are at the highest level of coronavirus risk and the other five are at the second-highest level, based on the aggregate scoring system used by the Michigan Department of Heath and Human Services.

The scale used by the MDHHS has six levels – “low” plus AE levels – and examines factors such as new cases and deaths per capita, test positivity rates, number of tests administered and visits to health facilities. emergencies for symptoms of COVID-19.

The Grand Rapids and Kalamazoo regions and the Upper Peninsula are in Tier E, and the other five regions in the state are in Tier D.

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, 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

Eighty counties are at Level E when measuring daily new cases per capita and three at Level D.

The three Tier D counties: Mackinac, Alpena and Alcona.

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

Current scores are based on new cases reported from November 1-7. 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 the previous seven days (October 25-31).

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.
