Tuesday, October 20, coronavirus data by Michigan county: 5 more counties move to highest risk level
Michigan saw five more counties climb to the highest risk factor for the spread of the coronavirus, bringing the state’s total to 15 counties with an average of more than 25 new cases per day per 100,000 people.
The most recent counties to achieve the highest of four risk levels, based on a metric developed by the Harvard Global Health Initiative, are Gogebic (37 new cases per day per 100,000 population), Mecosta (28), Keweenaw (27), St. Joseph (27) and Claire (26).
They join Dickinson (66), Alger (61), Iron (59), Delta (58), Marquette (52), Calhoun (38), Mackinac (36), Cass (36), Menominee (33) and Ontonagon (32). ). ) counties coded in red.
There are 42 counties coded orange, meaning they reported 10 to 24 cases per day per capita over the past week. There are no counties coded green, which means less than one new case per day per capita.
Of Michigan’s 83 counties, 73 reported a week-over-week increase in cases, according to data from Oct. 6-19.
The map below is shaded according to the Harvard Institute metric. The arrows indicate whether the total number of cases between October 13 and October 19 has increased or decreased compared to the previous seven days (October 6-October 12).

Latest news on coronavirus testing
In the past seven days, 29 counties in Michigan have a positive coronavirus test rate of at least 5%, which is the level at which schools become unsafe to open according to the Centers for Disease Control and Prevention (CDC) of United States. That’s an increase of eight counties from the previous day.
Four counties have a rate above 10%: Dickinson (16.3%), Delta (11.8%), Mackinac (11.1%) and Clare (10.9%).
Note: The number of positive tests does not correspond to confirmed cases, because the same patient can be tested more than once.
The map below shows the seven-day average testing rate by county from October 12-18. Again, readers can hover their cursor over a county to see the underlying data. If you don’t see the map, click here.
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.
