People can become infected by consuming food or water contaminated with feces (stool) that contains the parasite. It is an infection of the upper small bowel that is usually self-limited. Watery diarrhea is the most common symptom of cyclosporiasis and can be profuse and protracted.
Oocysts must mature (sporulate) in the environment for days to weeks to become infective; therefore, direct person-to person (fecal-oral) transmission is unlikely. Cyclosporiasis is acquired through drinking or swimming in water contaminated with C. cayetanensis or from ingestion of contaminated produce.
It is found in many countries. But it’s most common in tropical and subtropical regions. In the United States, foodborne outbreaks of cyclosporiasis have been linked to various types of imported fresh produce, including raspberries, basil, snow peas, and mesclun lettuce; no commercially frozen or canned produce has been implicated. Most reported cases have occurred during the months of May through August, peaking in June and July.
Cyclosporiasis is characterized by watery diarrhea, loss of appetite, weight loss, abnormal bloating and cramping, increased flatus, nausea, fatigue and low-grade fever.
How to prevent cyclosporiasis?
• Avoid food or water that may have been contaminated with stool.
• When traveling, follow safe food and water habits.
