(WWJ) -- The number of new coronavirus outbreaks in Michigan schools and universities has more than doubled in the past week.
An updated list of 71 schools was released Monday by the Michigan Department of Health and Human Services, which puts out a report on school outbreaks once a week.
The largest outbreak was at Northwood University in Midland, where 25 confirmed cases of the virus were reported.
In Wayne County, outbreaks were reported at St. Paul On The Lake Catholic School in Grosse Pointe Farms and at Belleville High School.
Oakland County schools reporting outbreaks were Walled Lake Western High, Cranbrook and Avondale GATE Magnet School.
The most cases in all K-12 schools were at South Christian High School near Grand Rapids, where 21 students and staff members have the virus.
Last week, MDHHS reported there were outbreaks in 31 schools in Michigan.
What counts as a school "outbreak"? In accordance with the Council of State and Territorial Epidemiologists’ outbreak definition, educational institutions (i.e., grades K-12 and institutions of higher education) that have been found by their local health department to have two or more COVID-19 cases who may have shared exposure on school grounds and are from different households are included. Case counts for school-related outbreaks include those associated with before and after school programs (including school-sponsored sports). When applicable, outbreak reporting also includes cases originating from on-campus and off-campus student housing.
If your institution is listed, MDDHS says your local health department and school are investigating the outbreak and will contact you directly if you (or your minor/child) were possibly exposed to coronavirus on the school grounds.
