The outbreak that started at the Kellogg Center last week, has now been confirmed as Norovirus, which has affected close to 400 people.

Linda Vail with the Ingham County Health Dept. told 6 News, “There are a lot of questions about what they ate, where they were, that could eventually help us narrow down potentially how the whole thing got started.”

With numbers climbing daily, Vail expects to see those numbers continue to grow, especially with secondary cases now being reported.
