The table below provides the number of outbreaks that local health departments report to the Michigan Department of Health and Human Services every week.
COVID-19 outbreaks are generally defined as two or more cases with a link by place and time indicating a shared exposure outside of a household.
Local health departments report the number of new and ongoing outbreaks they are investigating by the setting of the outbreak. New outbreaks are those outbreaks that were first identified during the current reporting week. Ongoing outbreaks are those that had already been identified in previous weeks but have had at least one new associated case reported to the local health department in the last 2 weeks. New and ongoing outbreaks are counted only once (i.e., a new outbreak is not also counted in the ongoing outbreak category).
Many factors, including the lack of ability to conduct effective contact tracing in certain settings, may result in significant underreporting of outbreaks. 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.
