Babson College’s campus closed at 5pm Saturday to outsiders due to an outbreak of gastrointestinal illness caused probably caused by the Norovirus. More than 100 students and staff have been stricken with the sickness, which results in unpleasantness such as vomiting and diarrhea. Classes and other events on campus are canceled until Wednesday, April 1. Students are being asked to stay on campus so as not to spread the virus, which so far has not been known to have gone further into Wellesley.
