Classes and weekend activities have been canceled at Ursinus College in eastern Pennsylvania as the school deals with a mystery illness that has sickened more than 190 students.
University spokeswoman Esme Artz says at least 192 students have reported symptoms of a stomach infection. She says Friday's classes were canceled "out of an abundance of caution" but will resume Monday.
She says a handful of faculty and staff has also reported symptoms.
The school's dining hall was closed after students began complaining of vomiting, diarrhea and stomach pain Tuesday night. But health inspectors found no issues there, so the dining hall has reopened.
The school is working with Montgomery County health authorities to try to determine whether the ailment is foodborne or transmitted from person to person.
