Babson College in Wellesley, Mass., shut down at 5 p.m. Saturday because of a norovirus outbreak that has affected more than 100 students since Wednesday, the school reports. All classes and events have been suspended, and students have been asked to stay on campus and avoid congregating in groups to prevent the spread of the virus.
Symptoms of norovirus include nausea, vomiting, and diarrhea and last between 24 and 60 hours. Health officials do not believe the outbreak was food-borne and are still searching for the root cause.
The school plans to reopen Wednesday morning.
