Understanding Cyclosporiasis
Cyclosporiasis is an intestinal illness caused by the Cyclospora cayetanensis parasite, which spreads through contaminated food or water, not from person to person.
Common symptoms include watery diarrhea, loss of appetite, abdominal cramps, nausea, fatigue, and low-grade fever. Without treatment, symptoms can persist for over a month.
