Norovirus is making the rounds in Madison, Wisconsin, with five food-related outbreaks since last November.

Dane County health officials are still waiting for test results from the most recent outbreak. It took place Jan. 29 when at least 16 people had vomiting and diarrhea after eating sandwiches and other food at the Mandrake Road Church of Christ in Madison.

Also last month, 28 people got sick after eating at Erin’s Snug Irish Pub in Madison. The other outbreaks took place at a drama-filming session at Madison West High School, the Pyle Center at U W Madison, and a Madison art show.

Health department epidemiologist Amanda Kita-Yarbro says the five outbreaks in a three-month period are a first for her agency. She said it could have been spurred either by food workers or people attending the various events.
