More than 150 students have been sickened by a gastrointestinal illness at an eastern Pennsylvania college, health officials said Thursday.

Ursinus College canceled all classes and shut down dining halls for the remainder of Thursday, as well as of Friday, according to WTXF. As of Thursday afternoon, 153 students, staff and faculty have symptoms of the stomach illness and have contacted the school’s wellness center.

College spokeswoman Esme Artz initially said that 174 students were infected with the illness, but the number decreased when it was learned that some students were counted twice after contacting the wellness center and other health facilities, according to WXTF.
