Cause: Protozoan Cyclospora cayetanensis.

Illness and treatment: Symptoms include persistent watery diarrhea, nausea, loss of appetite, abdominal pain, fatigue and weight loss. Antibiotics are available to treat persistent symptoms.

Sources: Cyclospora are common in many developing countries. Transmission occurs through ingestion of contaminated food or water, often fresh fruit or vegetables. Outbreaks in the United States have been attributed to imported produce such as raspberries, basil and lettuce. Tests for cyclospora must be specifically requested.

Additional risks: Diarrhea may persist with immunosuppression.

Prevention: Wash produce thoroughly before it is eaten. If traveling to risk areas, consult with a travel clinic or the CDC Travelers’ Health website.

Recent Washington trends: 0 to 11 cases are reported yearly, mainly after international travel.

2010: Two cases were reported. One case had traveled to Italy while the other one did not report traveling outside of Washington

• To better characterize the epidemiology of this organism
