Michigan health officials have identified 138 new coronavirus outbreaks in the past week, including 37 related to long-term care facilities and 26 in K-12 schools.
The new outbreaks add to the 714 ongoing clusters, meaning there were a total of 852 active outbreaks monitored in the state as of Thursday, Jan.21, according to a Department of Health and Human Services report released on January 21. Monday 25 January.
Despite a slight increase in new outbreaks from the previous report, the total active outbreaks are down from 902 a week ago.
An outbreak is generally defined as an instance in which two or more cases are linked by location and time, indicating shared exposure outside of a household.
The clusters monitored by the local health services are included in the online epidemic tracker, which is updated weekly on Monday.
Outside of K-12 schools and colleges, the MDHHS does not identify specific locations or the number of coronavirus cases.
However, it lists the information by the eight health district regions of the state. (Note that these regions have different numbers than the MI Safe Start plan.)
By region, the distribution of clusters:
- Region 1 (Clinton, Eaton, Gratiot, Hillsdale, Ingham, Jackson, Lenawee, Livingston and Shiawassee counties): 123 clusters, 11 new and 112 outbreaks underway.

- A cluster was linked to an indoor community event, such as a meeting or concert.
Outbreaks will be removed from the database if there are no additional cases in a 14-day period, MDHHS officials said.
State officials note that the graph does not provide a full picture of outbreaks in Michigan, and that an absence of an outbreak identified in a particular setting does not prove that the setting is not experiencing outbreaks.
“Many factors, including the lack of the ability to conduct effective contact tracing in certain settings, can lead to significant underreporting of outbreaks,” the state’s website read.
