They say it's norovirus, but I'm still curious if they ate in the house or elsewhere. Probably in the house since no one else got it.

ANN ARBOR, Mich. - An investigation is underway after dozens of members of a sorority at the University of Michigan became violently ill. Some of the young women were so sick they had to be hospitalized. Health officials believe the culprit behind the illnesses may be something they all ate.

"Usually kind of hits you like a freight train," said Kristen Schweighoefer with the Washtenaw County Health Department.

The cleanup is already beginning after more than 30 members of the University of Michigan's chapter of Delta Delta Delta sorority became violently ill, sick with a virus, and you can imagine these women aren't the only ones concerned.

Health inspectors have been combing through the sorority house and conducting their own investigation, and now they're pretty sure they know what made these women so sick.

"Norovirus is sometimes mistakenly called stomach flu, and it's really the sudden onset and often violent onset of vomiting and diarrhea," Schweighoefer said.

The virus usually comes from contaminated food and spreads pretty quickly.

"Someone didn't wash their hands or was sick and preparing food, and that's how the food got contaminated," said Schweighoefer.

Officials still are not sure whether those who got sick contracted the virus inside the sorority house, but they do know they were most likely exposed to the virus last Thursday or Friday.

Everyone who became ill is expected to be just fine, but health officials say this outbreak can serve as a reminder for all of us.

"Stay home if you're sick and wash your hands to prevent spreading the illness to others," Schweighoefer said.

Members of the sorority are not saying much, but we do know they are taking precautions to make sure this doesn't happen again.

The University of Michigan says the virus has not been found anywhere else on campus and that the problem is isolated
