The age of all those infected ranged from 3 to 79 years old, with 11 people age 50 or older testing positive through secondary contact with the virus.

No one listed a county in the Upper Peninsula as their primary county of residence.

There were no secondary cases in Berrien, Kalamazoo, Lapeer, Livingston, Manistee, Midland, Ottawa or St. Clair county residents

There were only secondary cases in Isabella and Sanilac county residents.

The report doesn't make it clear whether secondary cases happened after people traveled or whether those people were infected in Ingham County and simply list the other counties as their primary place of residence.
