Notes:

Number of cases reported by outpatient clinics, hospitals, doctors offices and other health facilities. These cases represent testing for Michigan residents whether testing occurred within the State of Michigan or in other states.

Both Sexes category includes records with unknown sex.

All Ages category includes records with unknown age.

Rates are per 100,000 population for the specified age and sex group in the geographic area. Adding and subtracting the number shown after the ± symbol from the rate creates an interval indicating that the true rate lies between the lower and upper bounds with 95% statistical confidence. Please note that the number of cases is not limited to residents of the geographic area but includes any case reported by health care providers in the area.

"*" indicates the number of cases is too small (5 or less) to calculate a statistically reliable rate.
"**" indicates that this age category is too broad to allow meaningful rates to be calculated.
