Disease Reporting


Yersiniosis is a gastrointestinal disease caused by the bacterium Yersinia enterocolitica or Yersinia pseudotuberculosis. Clinical signs often include fever, diarrhea and abdominal pain, and may include mesenteric lymphadenitis that mimics appendicitis. The disease is relatively uncommon with approximately 35 cases being reported in Wisconsin annually. Yersiniosis usually occurs as a single isolated event, however, occasional outbreaks have been reported due to a common exposure.
