Michigan health officials are investigating a growing outbreak of cyclosporiasis that has sickened hundreds of people across the state [1].
The scale of the outbreak suggests a widespread contamination source, posing a significant public health risk to residents in southeastern Michigan and beyond.
The Michigan Department of Health and Human Services (MDHHS) confirmed the outbreak began around June 22 [1]. A spokesperson for the MDHHS said the situation is a "large and growing outbreak" [3].
Reports on the total number of cases vary among sources. Some officials reported more than 170 cases [1], while other reports state over 225 people have been sickened [2]. The parasite is known for causing "explosive diarrhea" [4].
Geographic data also shows a wide spread. Health officials initially identified at least seven affected counties [3], though other reports indicate as many as 21 counties are involved [2]. Monroe County has been particularly hard hit, with 70 reported cases [3].
Cyclosporiasis is caused by the Cyclospora cayetanensis parasite. It is typically contracted through contaminated food or water. Health officials said they are currently investigating the source of the outbreak, but the specific cause remains unknown [3, 5].
Officials are urging residents to monitor for symptoms and report illnesses to local health departments to help identify the contaminated product. The investigation continues as the state attempts to contain the spread of the parasite [5].
“"large and growing outbreak"”
The disparity in case numbers and affected counties suggests the outbreak is evolving rapidly. Because cyclosporiasis is often linked to imported produce, the investigation will likely focus on the supply chain of fresh fruits and vegetables distributed across southeastern Michigan.
