According to the Centers for Disease Control and Prevention, Michigan has 14 counties with high levels of COVID-19 in the community this week.

CDC uses Community standards Placing counties into one of three buckets to determine the risk of Covid: low (green), medium (yellow) or high (orange).

The CDC recommends wearing a mask when in public at home. Regardless of vaccination status, districts were at higher community levels. However, people with symptoms, a positive test or exposure to someone with Covid-19 should wear a mask regardless of where they live, the CDC says.

The top 14 counties this week are: Calhoun, Clare, Clinton, Dickinson, Eaton, Ingham, Ionia, Iron, Lapeer, Macomb, Midland, Schoolcraft, Shiawassee and Washtenaw counties.

Michigan this week has 34 counties in the middle and 35 counties in the low community level of Covid-19.

CDC looks at cases and hospitalizations when determining the risk of Covid for an area. The goal is to prevent serious illness and limit the pressure on hospitals.

For community rankings, the CDC looks at three factors for each county: the percentage of hospital beds occupied by Covid patients, the number of Covid hospitalizations per capita and the number of COVID cases per capita.

When there are 200 or more new cases per 100,000 in the past week and (a) more than 10 new Covid-19 hospital admissions per 100,000 or (b) at least 10% of inpatient beds are occupied by Covid-19 patients.

If hospitalizations are particularly high, even a county with low cases may rank high, b CDC formula.

(Each county does not have a hospital, so each is assigned a health care area, a geographic region that contains at least one hospital. Counties are weighted for each county’s population as a measure calculated for the entire area.)

Here’s more about the COVID-19 situation in Michigan.

Michigan is reporting 2,086 new confirmed cases per day over the past week.

There were 2,086 new and confirmed cases in the region this week, an increase of 16.0% from the previous week.

Michigan has hovered around the 2,000-case-mark a day for most of the summer.

Michigan also reported 539 “probable” COVID cases per day this week.

Cases are “confirmed” when a positive result from the NAAT/RT-PCR test is obtained. Cases are “probable” when there is a reported antigen (rapid) test or if someone has symptoms and has been exposed to someone with Covid-19.

All graphics in this story, except the first one (which uses the CDC’s case calculations) are based solely on “confirmed” numbers.

The Michigan Department of Health and Human Services reports cases of Covid once a week. The department announced 18,375 confirmed and probable cases this week.

Michigan has reported 2.4 million confirmed cases of COVID and nearly 378,000 probable cases since the outbreak began.

The chart below shows the seven-day average for new, confirmed cases of Covid during the pandemic.

Michigan ranks 8th in the US in new cases per capita

Michigan’s COVID rate was the eighth highest in the U.S. last week, according to the New York Times.

Michigan had fewer COVID cases than last week, but 46 of the 50 states saw their rate decrease last week, so it moved up the list for the highest rate of Covid.

West Virginia, Kentucky, South Carolina, Alaska, North Carolina and Ohio had the most Covid cases per capita this week. Nevada, California, Washington, Utah, Montana and Wyoming had the lowest Covid rates.

For Covid hospitals, Michigan ranked 14th out of 50 this week. The state has the fourth-highest number of Covid-19 deaths per capita this week.

In the last seven days, 42 counties have been infected with the virus

42 of Michigan’s 83 counties had more cases this week than last week.

Many of Michigan’s largest counties have seen large increases in cases. Ingham County is up 39% from last week, Kalamazoo County is up 34%, Wayne County is up 32%, Oakland County is up 23%, Washtenaw County is up 20%, Macomb County is up 19% and Kent County is up 8%.

37 Michigan counties with the highest risk of cases

There are 37 counties at the highest level (level E) for cases, down from 43 counties last week.

MDHHS has five risk levels for COVID cases:

  • Level A: 7-19 cases per million per day
  • Level B: 20-39 cases per million per day
  • Level C: 40-69 cases per million per day
  • Level D: 70-149 cases per million per day
  • Level E: More than 150 cases per million

The counties with the highest Covid rates in Michigan this week were Steel, Dickinson, Washtenaw, Midland, School and Ingham counties.

The lowest Covid rates were in Alcona, Huron, Presque Isle, Leelanau, Antrim and Cheboygan counties.

The map below outlines the six levels of risk assessment from A to E. This is based on the millions of new cases reported every day between September 7-13.

The Covid issue does not tell the whole story. Indoor tests are not reported, so those are not included in the data. That’s why it’s key to look at the percent positivity of reported tests and data on hospitalizations and deaths.

The average test positivity is 18%

As of Monday, September 12, 18 of the 100 Covid tests reported to the state were positive.

The positivity rate hovered between 18 percent and 19 percent last week.

The World Health Organization considers high community transmission when the positivity rate is greater than 5%.

In January, Michigan’s rate rose 35 percent. It fell to 2 percent in early March before rebounding.

The graph below shows the percentage of Covid-19 tests that came back positive throughout the outbreak.
