Cyclospora Cases Top 18,000 Nationwide, Michigan Shows Signs of Slowing

The Centers for Disease Control and Prevention (CDC) has reported more than 18,000 possible cases of cyclosporiasis nationwide. This multi-state outbreak has seen Michigan emerge as a primary focus, though recent data suggests a potential decrease in new illnesses within the state.

Cyclosporiasis is an intestinal illness caused by the _Cyclospora cayetanensis_ parasite. Individuals typically contract the parasite by consuming contaminated food or water. Symptoms often include watery diarrhea, loss of appetite, weight loss, abdominal cramps, bloating, nausea, and fatigue.

Investigations into the current outbreak have largely pointed to contaminated lettuce as a potential source. Health officials continue to monitor the situation across affected states and gather more definitive information on the origins of the contamination.
