The CDC reports cases of Cyclospora cayetanensis, a parasitic infection, spreading across 17 states. This parasite causes severe diarrhea, often lasting weeks without treatment. Cases have climbed significantly in recent months, prompting health officials to issue public warnings about prevention.
Cyclospora spreads through contaminated water and food, particularly fresh produce like berries, lettuce, and herbs. The parasite enters the water supply when infected individuals don't practice proper hygiene after using the bathroom. Unlike bacterial foodborne illnesses, Cyclospora infections develop slowly, with symptoms appearing 7 to 14 days after exposure.
Infected people experience watery diarrhea, abdominal cramps, bloating, nausea, and fatigue. The illness can persist for weeks or months without antibiotic treatment. Children, older adults, and immunocompromised individuals face higher risks of severe complications.
To reduce infection risk, wash all fresh produce thoroughly under running water before eating or cooking. Avoid consuming produce from areas with known outbreaks. Pregnant women should be especially cautious, as Cyclospora can pass to the developing baby.
When traveling internationally, the CDC recommends drinking bottled or boiled water only. Avoid ice made from tap water and raw or undercooked foods.
If you develop persistent diarrhea lasting more than a few days, contact your doctor. Healthcare providers can order stool tests to confirm Cyclospora infection. Prescription antibiotics like trimethoprim-sulfamethoxazole treat the parasite effectively.
Restaurants and food handlers should follow strict sanitation protocols. Anyone handling food while experiencing diarrhea should not work with ready-to-eat items until symptoms completely resolve.
The CDC continues monitoring this outbreak. Parents should stay informed about which produce items pose current risks in
