Wayne County health officials are monitoring 27 potential cases of cyclosporiasis as a parasitic illness outbreak spreads across Michigan, sickening more than 300 people.
The local investigation involves collaboration between Wayne County Public Health, the Michigan Department of Health and Human Services, and the Michigan Department of Agriculture and Rural Development, along with other regional health agencies.
State health officials reported the surge in illnesses on July 2, 2026, noting that increased public awareness may be contributing to the rise in reported cases.
Symptoms of cyclosporiasis typically appear two to 14 days after exposure to the Cyclospora cayetanensis parasite.
Understanding Cyclosporiasis
Cyclosporiasis is an intestinal illness caused by the Cyclospora cayetanensis parasite, which spreads through contaminated food or water, not from person to person.
Common symptoms include watery diarrhea, loss of appetite, abdominal cramps, nausea, fatigue, and low-grade fever. Without treatment, symptoms can persist for over a month.
Health officials recommend thoroughly rinsing fresh fruits and vegetables under running water, scrubbing firm produce, and washing hands before preparing food to reduce infection risk.
