# Clusters of Severe Stomach Illness Reported Across the U.S.
Public health authorities are tracking an uptick in cyclospora infections spreading across multiple U.S. states. The parasite, transmitted through contaminated food and water, causes severe gastrointestinal illness characterized by persistent diarrhea, cramping, and fatigue.
Cyclospora cayetanensis is a single-celled parasite that typically flourishes in warm climates and spreads when contaminated produce reaches consumers. The current clusters represent higher-than-normal case counts, according to public health experts monitoring the outbreaks.
Symptoms emerge 7 to 10 days after exposure and can last weeks without treatment. Infected individuals experience watery diarrhea, loss of appetite, weight loss, and abdominal pain. The illness rarely becomes life-threatening but can cause severe dehydration, particularly in older adults and immunocompromised individuals.
The CDC and state health departments are investigating the source of contamination. Previous cyclospora outbreaks have been linked to imported raspberries, basil, mesclun lettuce, and snow peas. Health officials are working to identify which foods are currently responsible and prevent further distribution.
Treatment involves prescription antibiotics, specifically trimethoprim-sulfamethoxazole, which eliminate the parasite. Without treatment, symptoms may persist for months. Supportive care including hydration and electrolyte replacement helps manage symptoms while the antibiotic takes effect.
Consumers can reduce their risk by washing produce thoroughly, buying from reputable sources, and avoiding high-risk imported items during peak infection seasons. Proper food handling and refrigeration of perishables also help prevent transmission.
People experiencing persistent diarrhea, especially after consuming raw vegetables, should contact their healthcare provider. Stool samples confirm cyclos
