The Department of Health and Human Services told ABC News today that its state laboratory did confirmatory testing for the norovirus outbreak with the University of Michigan.
University spokeswoman Kim Broekhuizen estimated between 100 and 150 students were sickened.
One student was hospitalized for dehydration, Broekhuizen said.
The outbreak was first identified in university housing at the school's West Quad and South Quad, the university said, adding that officials are working to determine the source of the outbreak.
Last week in Pennsylvania, more than 200 students at Ursinus College were sickened by a norovirus outbreak at the school, according to ABC station WPVI in Philadelphia. In New Hampshire, more than 500 people have become ill from norovirus this year, and the disease prompted a private school in Concord to close Friday, according to ABC affiliate WMUR-TV.
Norovirus can be prevented by proper hand washing and general cleanliness, the CDC says.
