Data: State of Michigan Provides Outbreak Reporting by Region

Print Friendly and PDF

The State of Michigan is now reporting on its site the number of COVID-19 outbreaks that local health departments report to the Michigan Department of Health and Human Services every week. The state defines outbreaks as “two or more cases with a link by place and time indicating a shared exposure outside of a household.”

New outbreaks are first identified during the current reporting week, while ongoing outbreaks have already been identified in previous weeks but have had at least one new associated case reported to the local health department in the last two weeks. New and ongoing outbreaks are counted only once, which means a new outbreak is not also counted in the ongoing category. It is worth noting that challenges with contact tracing could lead to underreporting of outbreaks.

Data is updated each Monday. The State of Michigan’s site notes, “This chart does not provide a complete picture of outbreaks in Michigan, and the absence of identified outbreaks in a particular setting in no way provides evidence that, in fact, that setting is not having outbreaks.”
