Cyclosporiasis Outbreak Claims Two Lives in Michigan
Two deaths have been reported in Michigan due to a cyclosporiasis outbreak.
San Francisco Oakland San Jose, CA, August 3, 2026 —
Authorities in Michigan have confirmed two fatalities linked to an ongoing outbreak of cyclosporiasis, a parasitic illness. The Michigan Department of Health and Human Services (MDHHS) has been monitoring the situation and working to identify the source of the outbreak.
Cyclosporiasis is an intestinal illness caused by the microscopic parasite Cyclospora cayetanensis. Individuals typically contract the illness by consuming food or water contaminated with the parasite’s feces. Symptoms often include frequent, sometimes watery, bowel movements, loss of appetite, weight loss, cramping, bloating, gas, nausea, fatigue, and vomiting. Some people infected with the parasite may experience no symptoms at all.
The MDHHS has not yet provided specific details regarding the victims, including their ages or the exact dates of their deaths. Investigations are underway to determine the common factors among those affected, which could include specific food products or locations visited.
The reported deaths highlight the potential severity of cyclosporiasis, particularly for individuals with weakened immune systems. Public health officials are advising residents to practice good hygiene, including thorough handwashing with soap and water after using the restroom and before preparing or eating food.
Further details regarding the source of the contamination, the total number of cases, and any specific public health recommendations are expected as the investigation progresses. Residents experiencing symptoms consistent with cyclosporiasis are encouraged to consult with their healthcare providers.
