Georgetown canceled its scheduled Saturday football matchup at Colgate and Friday’s Potomac Relays at American due to an outbreak of norovirus on the Hoya campus. More than 175 students have fallen ill from the disease, including student-athletes.

“Because several members of the teams have been infected and others have been exposed, and because the infection is contagious, after discussion between medical personnel at the universities and the Patriot League, the decision has been made not to play the football game or participate in any portion of the meet,” said Athletics Director Bernard Muir.

Make-up dates have not been scheduled.

Norovirus is highly contagious and causes vomiting, stomach cramping, fever, headaches and diarrhea. It typically lasts a day or two and spreads swiftly through person-to-person contact or contact with food, drink or other objects that have been contaminated. Cruise ships and hotels are common sites for outbreaks.

Many of the ill Georgetown students reported eating at the main campus dining hall, which was closed and sanitized on Wednesday. Most residence hall kitchens, common spaces, lounges and bathrooms were cleaned and sanitized Thursday. Some students have been hospitalized.
