STORRS, Conn. (CBSNewYork/AP) — UConn health officials have begun interviewing students affected by an unspecified illness on campus, hoping to pinpoint what led to the outbreak.

At least 10 UConn students have been treated over the last three days at nearby Windham Hospital in Willimantic, Connecticut for symptoms such as nausea, vomiting and weakness. Other patients have notified UConn Health Services of their illnesses.

An inspector from UConn’s Environmental Health & Safety office has been interviewing the students to learn more about their recent health history and any connections they may have to one another.

CBS affiliate WFSB-TV, Hartford reported that most of the students lived in the same Buckley residence hall. One student, Eiman Kahn, told WFSB on just one floor it was “like four people who didn’t stop vomiting all night” and one had to go to the hospital.

Some thought the outbreak might have been connected with the school’s cafeteria, the station reported.

But Stephanie Reitz, a school spokeswoman, said there is no current evidence that the illness is food related.

She extra cleaning crews were brought in to scrub the dorm’s common areas.
