Flu rips through University of Michigan, bringing CDC to campus to investigate spread

ANN ARBOR, Mich. – Influenza is sweeping the University of Michigan’s Ann Arbor campus, with 528 cases diagnosed at the University Health Service since Oct. 6.  

The outbreak is so sudden and large – 313 cases were identified the week of Nov. 8 alone, and 37% of flu tests that week were positive – that it has drawn the attention of federal health leaders.
