The good news is that the City of Detroit got their act together and the growth rate for new Covid-19 cases slowed down to 2.3% per day.
Oakland County and Wayne County (less Detroit), the county north-west and south of the City of Detroit currently have fewer cases than the City of Detroit but higher growth rates at 4.5%.
At the high end among the counties with more than 100 confirmed cases are Genesee County (home of Flint, Michigan) with growth rate of 7% and Saginaw County with a growth rate of 8.4%.
There is a lot of slush in these growth rate numbers. They are calculated on the basis of the number of new cases from April 9-through-April 12.
Genesee county (Flint), coming out of nowhere, will pass Detroit on May 24 if growth rates don't change.
Obviously, focus needs to shift to Flint and Saginaw.
