COVID outbreaks in schools quadruple, total number of clusters climbs 18% in Michigan
Michigan health officials identified 356 active outbreaks of COVID-19 last week, an 18% increase from the previous week.
The latest weekly outbreak report included 106 new clusters, including 30 linked to K-12 schools, 19 to long-term care facilities and 13 linked to retail establishments.
In addition, there have been 250 active and ongoing outbreaks that have been carried over from previous outbreak reports. The Michigan Department of Health and Human Services publishes an updated list online every week.
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.
Some settings, such as nursing homes and youth programs, are easier to track outbreaks because of the testing requirements. Others, like social gatherings, bars and restaurants, are more difficult. Thus, the state warns that its number of epidemics is probably lower than the reality.
Schools have seen one of the largest increases in known active outbreaks, from 11 clusters a week ago to 45. School outbreaks have been reported in 23 counties including Berrien, Delta, Gladwin, Genesee, Gratiot, Hillsdale, Ionia, Jackson, Kalamazoo, Lapeer, Lenawee, Livingston, Marquette, Mason, Midland, Monroe, Oakland, Osceola, Ottawa, Shiawassee, St. Joseph, Washtenaw and Wayne counties.
The largest groups involved 172 University of Michigan students and staff, 23 Adams Elementary School students and staff, 16 Eastern Michigan University students, and 14 University of Michigan students and staff. Gladwin Elementary School.

Outbreaks will be removed from the database if there are no additional cases within a 14-day period, state officials from the MDHHS said.
State officials note that the graph does not provide a complete picture of outbreaks in Michigan, and the absence of an outbreak identified in a particular frame does not prove that the frame does not have outbreaks.
“Many factors, including the lack of the ability to perform effective contact tracing in certain settings, can lead to significant underreporting of outbreaks,” the state’s website read.
