The CDC reports more than 4,100 people across the United States have been infected by a parasitic stomach illness.
The Centers for Disease Control and Prevention (CDC) confirmed that more than 4,100 people across the United States have been infected by cyclosporiasis, a gastrointestinal illness caused by the Cyclospora cayetanensis parasite. While 308 people have been hospitalized across 41 states, no deaths have been reported. Symptoms, which include frequent diarrhea, fatigue, and stomach cramps, typically appear one week after consuming contaminated food or water. While many cases have been linked to lettuce, investigators are still identifying specific sources. The Food and Drug Administration recently corrected a previous finding, declaring a positive result from Taylor Farms iceberg lettuce as a false positive, though the agency continues to investigate Mexican facilities as a likely source. Health officials note that the parasite is difficult to trace because symptoms often appear days after consumption, making it hard for patients to recall specific meals. Experts recommend washing fresh produce thoroughly and seeking medical care if symptoms persist. Patients are advised to wait at least seven days before seeking a stool sample test to ensure the parasite is detected.
