U.S. public health officials are investigating an outbreak of cyclosporiasis, a gastrointestinal illness caused by the parasite Cyclospora. The Centers for Disease Control and Prevention (CDC) reports that cases have been detected across multiple states, with one CDC update listing 145 confirmed cases in 17 states between May 1 and June 16, including 20 hospitalizations. Other reporting cites a broader toll, stating that more than 400 cases have been recorded across 18 states as the investigation continues.
Cyclospora is associated with exposure to contaminated food and water. Health authorities note that the parasite can spread through raw produce and through water contaminated with human feces. Symptoms can include frequent watery diarrhea—sometimes described as explosive—along with intestinal cramps, nausea, fatigue, loss of appetite, low-grade fever, and vomiting. The CDC is working to identify the source of contamination to help prevent additional infections.
