‘Large and sudden’ flu outbreak brings CDC investigators to University of Michigan

Hundreds of students at a Michigan university have been sickened with the flu, triggering an investigation into what the Centers for Disease Control and Prevention have called a “large and sudden” outbreak.

Since Oct. 6, 528 cases have been recorded across the University of Michigan’s Ann Arbor campus in Washtenaw County. Approximately three-quarters of those infected were unvaccinated against influenza, according to a statement from the university.
