Cyclosporiasis is an intestinal illness caused by the _Cyclospora cayetanensis_ parasite. Individuals can become infected by consuming food or water contaminated with the parasite. Symptoms typically include watery diarrhea, loss of appetite, weight loss, abdominal cramps, bloating, nausea, and fatigue. The illness can last from a few days to a month or longer, and symptoms may recur.
