Officials say the number of students at a Pennsylvania college reporting symptoms of a stomach illness has now topped 200, but the source of the ailment remains a mystery.

Ursinus College spokesman Tom Yencho told The Philadelphia Inquirer  on Saturday that he believed a few more reports had trickled in overnight.

Twenty-two students were treated at hospitals earlier in the week, but none were admitted.

The university canceled Thursday and Friday classes and weekend activities but planned to resume classes Monday.

 The school's dining hall was closed after students began complaining of vomiting, diarrhea and stomach pain Tuesday night, but it was reopened after an inspection.

Montgomery County health investigators are trying to determine whether the ailment is foodborne or transmitted from person to person.
