Cyclospora is a microscopic single-celled parasite that is passed in people’s feces. If it comes in contact with food or water, it can infect the people who consume it.
Symptoms of cyclosporiasis begin an average of 7 days (range, 2 days to ≥2 weeks) after ingestion of sporulated oocysts.
The major symptom is watery diarrhea lasting a few days to a few months. Additional symptoms may include loss of appetite, fatigue, weight loss, abdominal cramps, bloating, increased gas, nausea, vomiting and a low fever.
In the US, as of August 10, 2015, the CDC had been notified of 457 ill persons with confirmed Cyclospora infection from 29 states in 2015.
