In February 2016 twenty four individuals who attended the Midwest Shabbaton events in Lawrence, Kansas became ill with norovirus. The Chabad on Campus hosted the event from February 26-28, 2016. Groups from Kansas, Illinois, Minnesota, Missouri, Indiana, Nebraska, and Wisconsin attended. Epidemiologic and clinical data collected were insufficient to determine if a food or drink item was the source of illness, or if illness was spread person-to-person. Three stool specimens were positive for norovirus.
