If your child has had diarrhea lasting more than a few days, it may not be a typical stomach virus. A nationwide outbreak of Cyclospora, a microscopic parasite that causes prolonged diarrhea, has affected thousands of people across the United States this summer. Public health officials are investigating contaminated produce as the likely source, and certain recalled iceberg lettuce products have been linked to part of the outbreak.

What is Cyclospora?

Cyclospora is a parasite that infects the intestines after a person eats contaminated food or drinks contaminated water. Unlike many common stomach viruses that improve within 24–72 hours, Cyclospora infections often cause symptoms that can last days to weeks without treatment.

Common Symptoms

Children and adults may experience:

• Frequent watery diarrhea
• Loss of appetite
• Stomach cramps
• Nausea
• Fatigue
• Weight loss
• Bloating
• Low-grade fever (occasionally)
• Symptoms may improve briefly and then return again days later.

When Should You Call Your Pediatrician?

If your child has:

• Diarrhea lasting longer than 3–5 days
• Severe abdominal pain
• Signs of dehydration (dry mouth, decreased urination, lethargy)
• Bloody diarrhea
• Persistent vomiting
• Significant weight loss

they should be evaluated. Diagnosis requires a special stool test, and Cyclospora does not show up on every routine stool culture.

Can It Be Treated?

Yes. Once diagnosed, Cyclospora is typically treated with a prescription antibiotic called trimethoprim-sulfamethoxazole (Bactrim®), which usually shortens the illness significantly.

How Can Families Protect Themselves?

Current recommendations include:

• Wash fresh fruits and vegetables thoroughly.
• Stay informed about produce recalls.
• Avoid recalled lettuce products.
• Practice good hand hygiene.
• Drink plenty of fluids if diarrhea develops to prevent dehydration.
