Monroe County reported 41 new coronavirus cases over the weekend, while Isabella County added 25 new cases to its growing caseload.
As of Monday morning, seven Michigan counties are in the red or orange zone, based on a metric developed by the Harvard Global Health Initiative to assess coronavirus risk levels.
Isabella, which has reported 143 new cases in the past week, the result of an outbreak linked to Central Michigan Univ ersity, remains red zone, which Harvard officials recommend for lockdown. Monroe is one of six counties coded orange, which signals heightened concern. The other five counties: Macomb, Branch, Menominee, Calhoun and Saginaw.
The Harvard institute metric looks at a seven-day average of new cases per 100,000 residents. The newest assessment is based on data for Aug. 24-30.
At the other end of the spectrum, 13 counties are coded green, the lowest risk level.
That includes eight counties with no new cases in the past week: Alger, Baraga, Keweenaw and Schoolcraft in the Upper Peninsula, and Lake, Montmorency, Oscoda and Presque Isle in the northern Lower Peninsula.
Also in the green zone: Chippewa, which includes Ste. Sault Marie; Alpena; Gladwin, Osceola, and Missaukee counties.

Latest on coronavirus testing
Only two Michigan counties have a positive rate of at least 5% in coronavirus tests reported in the last 14 days ending Aug. 30. The state is administering an average of an average of almost 30,000 tests a day.
Macomb had the highest 14-day average at 7.1% and Isabella County was at 5.6%. Note: The number of positive tests does not match confirmed cases because a single patient may be tested multiple times.
The World Health Organization says schools are safe to reopen if fewer than 5% of coronavirus tests over the past two weeks are positive.

Below are online databases that allow readers to look up county-level data for each of the last 20 days.
Cases by day it was reported to the state
First is a chart 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 became sick days before.
You can call up a chart for any county, and you can put your cursor over a bar to see the date and number of cases.

(In a few instances, a county reported a negative number (decline) in daily new cases, following a retroactive reclassification by the Michigan Department of Health and Human Services. In those instances, we subtracted cases from the prior date and put 0 in the reported date.)
Cases by day of onset of symptoms
Below this chart shows new cases for the past 20 days based on onset of symptoms. In this chart, numbers for the most recent days are incomplete because of the lag time 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 University of Michigan’s Department of Epidemiology, which has access to sub-county data collected by the Michigan Department of Health and Human Services.
The interactive maps break down the state into 10 kilometer hexogons to provide more a more localized look at where coronavirus cases are occurring. You can click here to get to the research project website.
The first map looks at confirmed and probable coronavirus cases in the past week. You can click on a hexagon to see the underlying data.
You can use the triangle button at the upper right of the map to toggle to the second map, which shows total confirmed coronavirus cases and deaths since the start of the pandemic.
Latest daily report
On Sunday, the state reported 529 new cases of the novel coronavirus and six deaths.
Michigan is averaging 687 new cases and 11 new deaths per day.

COVID-19 PREVENTION TIPS:
In addition to washing hands regularly and not touching your face, officials recommend practicing social distancing, assuming anyone may be carrying the virus.
Health officials say you should be staying at least 6 feet away from others and working from home, if possible.
Use disinfecting wipes or disinfecting spray cleaners on frequently-touched surfaces in your home (door handles, faucets, countertops) and carry hand sanitizer with you when you go into places like stores.
Michigan Gov. Gretchen Whitmer has also issued executive orders requiring people to wear face coverings over their mouth and nosewhile in public indoor and crowded outdoor spaces. See an explanation of what that means here.
