Cyclospora infection (cyclosporiasis) causes watery, and sometimes explosive, diarrhea. The one-celled parasite that causes cyclospora infection can enter your body when you ingest contaminated food or water. Fresh produce is the culprit in many cases of cyclospora infection.
Because diarrhea can be caused by many things, it can be difficult to diagnose cyclospora infection unless a specialized stool test is done. Treatment for cyclospora infection is antibiotics. Food safety precautions may help prevent the disease.
