About 40 students at the Lawrenceville campus were transported to area hospitals or treated at the school after experiencing symptoms of a gastrointestinal illness on Wednesday night, according to the University’s website.

Another 18 reported to the university health center on Thursday.

Many of the students have been discharged from the hospital and are back on campus.

Officials believe norovirus is to blame.

An outbreak began a week ago and is still ongoing at nearby Princeton University where about 60 students have been sickened so far.

Symptoms of norovirus include diarrhea, vomitting, nausea, and stomach cramping.

The university said it is cleaning all dorm bathrooms and buildings.

No classes or events have been cancelled.

To prevent the spread of the virus students are being urged to wash their hands frequently and avoid sharing drinks, food, eating utensils and cups.
