Some 50 attendees at the world’s leading feminist science fiction convention. WisCon32, which rocked Madison, Wisconsin’s Concourse Hotel May 23-25, 2008, were stricken with symptoms similar to those of stomach flu.

Officials with Dane County and the Madison Public Health Department think some attendees might have been exposed to the illness before the convention since they developed symptoms so soon after arriving. The sick ones may have then infected others through personal contact and shared access to food.
