Cyclosporiasis is caused by the protozoan Cyclospora cayetanensis. It has an incubation period of about 1 to 14 days after exposure and is classically linked to ingestion of contaminated fresh produce, including raspberries. This combination—cyclosporiasis plus a 1–14 day incubation and association with fresh produce—fits Cyclospora cayetanensis best. Other protozoa cause infections with different incubation timelines and common sources: Giardia lamblia (giardiasis) is typically 1–3 weeks and linked to contaminated water; Entamoeba histolytica (amebiasis) can have a more variable incubation and is fecal-oral; Cryptosporidium parvum (cryptosporidiosis) usually has a 2–10 day incubation and is often related to contaminated water.
