First US Deaths Linked to Cyclospora Outbreak Reported in Michigan
Michigan has reported the first two deaths in the U.S. linked to a cyclospora outbreak, a diarrhea-causing parasite. The individuals had pre-existing health conditions that may have been exacerbated by the intestinal illness and dehydration.
Detroit, MI, August 3, 2026 —
Michigan health officials have confirmed the first two deaths in the United States associated with a recent outbreak of cyclospora, a parasite that causes an intestinal illness. The individuals who died had pre-existing health conditions, which officials noted may have been worsened by the effects of the infection, including dehydration.
The cyclospora parasite, Cyclospora cayetanensis, is typically spread through contaminated food or water. Infection can lead to symptoms such as diarrhea, loss of appetite, weight loss, cramping, bloating, gas, nausea, and fatigue. Symptoms often begin several days to a week after consuming something contaminated and can last for weeks or even months. Some individuals may experience recurring symptoms.
While the specific source of the outbreak in Michigan has not been definitively identified, health departments typically investigate potential links to produce, such as fresh fruits and vegetables, or contaminated water sources. Public health agencies advise thorough washing of all produce and practicing good hygiene, including frequent handwashing, to reduce the risk of infection.
The severity of cyclosporiasis can vary, with some individuals experiencing mild symptoms while others can become severely ill. Those with weakened immune systems or underlying health issues may be at a higher risk for complications. The two individuals who passed away in Michigan had such pre-existing conditions, and the intestinal illness and subsequent dehydration are believed to have exacerbated their health status.
Health authorities are continuing to monitor the outbreak and are working to identify the source to prevent further spread. Further details regarding the identities of the individuals or the specific nature of their pre-existing conditions were not immediately available.
