Health officials treat E. coli cases

At least 11 university students and a 3-year-old Dane County resident have experienced symptoms of severe intestinal illness caused by infection with the E. coli bacterium. Three students were initially hospitalized, but all except one have been released.

The source of the E. coli infection is under investigation by University Health Services and the Wisconsin Division of Public Health, says UHS epidemiologist Craig Roberts. All of those who have been interviewed attended a pancake tailgate party at the UW Stock Pavilion prior to the Wisconsin vs. Indiana football game Saturday, Oct. 6.

UHS began receiving reports Thursday, Oct. 11 from students who were experiencing abdominal cramps, severe or bloody diarrhea and fever. In all cases the onset of symptoms began Oct. 8-11. Lab tests completed Oct. 16 indicate the presence of E. coli O157:H7.

“Everything that can be done by the university is being done, from a medical, public health and student support standpoint, to respond to this health concern,” says Roberts, noting that UW–Madison is working closely with officials from the Wisconsin Division of Public Health, along with city and county health departments.

E. coli infections can occur as isolated cases or as part of an outbreak, says Roberts. People can become infected in various ways, including through contact with tainted food, water or animals.

E. coli can cause bloody diarrhea, stomach cramps, fatigue, nausea and sometimes chills and fever. It can also lead to complications in younger children, adults with other health problems and older adults. Illness onset can range from three to eight days after exposure.

Thorough hand washing can minimize the risk of infection. This is especially important after using the restroom, before cooking or eating, and after contact with anyone displaying intestinal symptoms. People who have intestinal illness should not handle food prepared for others.

Students who attended the Oct. 6 event and experienced symptoms between Oct. 7-13 should contact UHS, (608) 265-5600. Other members of the community who attended and experienced symptoms should contact their health care provider or local public health agency.

UHS also has information about the disease.

A fact sheet on E. coli O157:H7 is also available on the Wisconsin Division of Public Health.
