Cyclospora cayetanensis

Cyclosporiasis is an intestinal illness caused by an infection with a microscopic one-celled parasite named Cyclospora cayetanensis. The first known human cases of cyclosporiasis were reported in 1979.

People can become infected with Cyclospora by consuming food or water contaminated with the parasite. People traveling to countries where the disease is endemic may be at increased risk for infection.
