Gastrointestinal Illness Affects Over 170 in Michigan
Michigan is currently facing an outbreak of cyclosporiasis, a gastrointestinal illness caused by the parasite Cyclospora cayetanensis, affecting more than 170 residents. The exact source of the outbreak remains unidentified, but this parasite is known to be transmitted through the consumption of contaminated fresh produce such as berries, leafy greens, and herbs.
Dr. Teena Chopra, a professor at Wayne State University School of Medicine, emphasized the importance of hygiene in preventing infection. She advised, “What I would advise to the community is, please wash your fruits and vegetables thoroughly under running water, scrub them, and then consume them. If you have cut vegetables, don’t leave it outside — try to refrigerate it. Practicing good hand hygiene before preparing food is also very important.”
The Michigan Department of Health and Human Services detected the first case on June 22, with confirmed infections spreading across 17 counties. As of June 30, the distribution of cases by county is as follows:
- Monroe: 70
- Lenawee: 33
- Washtenaw: 21
- Wayne: 12
- Jackson: 7
- Shiawassee: 7
- 24 cases in 11 other counties and the City of Detroit.
Dr. Natasha Bagdasarian, Michigan’s chief medical executive, mentioned that efforts are ongoing to trace the outbreak’s origin. Local health departments are actively gathering data through patient interviews and analyzing it for commonalities in a statewide database. “These are the types of activities that public health is always doing quietly behind the scenes that when things are working, nobody really hears about,” Dr. Bagdasarian stated. “Our job is to prevent things like this from becoming an issue, and when they do become an issue, to very quickly investigate.”
Symptoms associated with cyclosporiasis can manifest between two to 14 days post-exposure and usually involve watery diarrhea, explosive bowel movements, abdominal discomfort, and a decrease in appetite. Dr. Chopra warned that untreated infections could lead to repeated bouts of diarrhea due to ongoing intestinal cell infection, thus urging those with symptoms to seek medical testing and treatment. Although the illness might cause damage to the small intestine if left untreated, most cases respond well to antibiotic treatment.
Dr. Bagdasarian also cautioned that the ongoing high temperatures in Michigan could exacerbate dehydration caused by the illness, posing additional health risks.
