Michigan reported 758 active COVID-19 outbreaks last week, up 5.7% from the prior week when there were 717.
The health department’s latest outbreaks report, published Monday, Oct. 11, included 161 new outbreaks and 597 that carried over from previous weekly reports.
Among the new outbreaks, 81 were linked to K-12 schools, 30 came from long-term care facilities, and 11 were tied to childcare/youth programs.
Some settings, like nursing homes and youth programs, are easier to track outbreaks due to testing requirements. Others like social gatherings, bars and restaurants are more challenging. Thus, the state warns that its outbreak count is likely less than reality.
Throughout the pandemic, an outbreak has generally been defined as an instance in which two or more cases are linked by a place and time, indicating a shared exposure outside of a household. However, Michigan recently changed that definition to “three or more cases” when referring to schools, in an effort to “promote consistent reporting amongst states.”

Outside of K-12 schools and colleges, MDHHS is not identifying specific locations or the number of coronavirus cases. However, it is listing the information by the state’s eight health district regions. (Note those regions have different numbers than the MI Safe Start Plan.)

Outbreaks will be removed from the database if there are no additional cases through a 14-day period, state MDHHS officials have said.
State officials note that the chart does not provide a complete picture of outbreaks in Michigan, and an absence of identified outbreak in a particular setting is not evidence that the setting is not having outbreaks.
“Many factors, including the lack of ability to conduct effective contact tracing in certain settings, may result in significant under-reporting of outbreaks,” the state’s website reads.
