And the University said the virus may have spread further.
The highly contagious virus spreads easily from person to person and can be transmitted even two days before an outbreak, so fellow students may not even know if they’ve been exposed, CBS 2′s Kathryn Brown reported.
University health officials sent out an email alert warning students of the campus outbreak.
“It was kind of a shock. I didn’t really know what they were, we’ve all been vaccinated against it,” said freshman Amy DesMarais.
