Federal health experts are visiting the University of Michigan to learn more about hundreds of flu cases diagnosed by the campus health service.
“While we often start to see some flu activity now, the size of this outbreak is unusual,” said Dr. Juan Luis Marquez, medical director at the Washtenaw County health department.
There have been more than 500 cases diagnosed since Oct. 6, with 77% of those afflicted not vaccinated against the flu, the university said Monday.
