Cyclosporiasis is an intestinal illness caused by the microscopic parasite Cyclospora cayetanensis. It primarily affects humans, causing prolonged watery diarrhea, and is most often linked to consuming contaminated fresh produce or water. While found globally, outbreaks have been common in developed countries due to imported produce.

The parasite *Cyclospora cayetanensis* was first observed in stools in 1979 but was recognized as a significant human pathogen in the early 1990s. Its historical significance grew due to large foodborne and waterborne outbreaks, particularly in North America, often linked to contaminated fresh produce. This led to increased public health awareness and research into its epidemiology.
Cyclosporiasis is transmitted through the fecal-oral route, primarily by ingesting food or water contaminated with mature *Cyclospora cayetanensis* oocysts. Direct person-to-person transmission is unlikely because the oocysts passed in stool are not immediately infectious; they require days to weeks to sporulate (mature) in the environment. Outbreaks are frequently associated with contaminated fresh produce such as raspberries, basil, or leafy greens.
