WC Community Spread Risk Level. 

Risk Level Key
This is a measure of the risk of community spread based on
COVID-19 case data collected using the Michigan Disease Surveillance System database It is a weighted factor based on the average number of cases per day, normalized to a rate per 1 million population, the 4-week +/- trend rate, and the county's overall average positive rate as calculated by the state of Michigan. If the county positive rate is less than the normalized rate per 1 million population, the positive rate is not factored in. This follows MDHHS guidelines. The data in this analysis represents the 42 non-Detroit communities in Wayne County. This measure is based on a 15-day rolling average to the date noted.
