Owain Buchnea, a first-year computer science student at the University of Guelph, was hanging out with his friends in Prairie Hall of South Residence, a coed student housing building on campus, for the second night in a row on Monday.
A little over 24 hours later, around 4:30 a.m. Wednesday morning, he began vomiting and having diarrhea for about four-and-half hours. By Thursday, his stomach problems had eased, but he started having flu-like symptoms like a sore throat and cough that continued into Friday.
