College spokesperson Esme Artz says 174 students have shown signs of a stomach infection. Overnight, two students went to the emergency room, and two others were taken to a hospital Thursday morning. The school closed its cafeterias and snack bar after students began complaining of vomiting, diarrhea, and stomach pain Tuesday night. Classes remain open, but weekend events have been canceled. The school is working with Montgomery County health authorities to try to determine whether the ailment is foodborne or transmitted from person to person. Ursinus has partnered with Wawa, Wegman's, local pizza shops, and a bakery to provide food while the cafeterias are closed.
