Rotavirus is a virus that causes diarrhea among persons in all age groups, but is most common among children between 6 months and 2 years old. Infants less than 3 months old rarely develop diarrhea from rotavirus infection. Since rotavirus infection is not a reportable disease in Wisconsin, the specific incidence is unknown.
