How do people get Cyclospora cayetanensis?

Explanation:
The key idea is that Cyclospora cayetanensis is transmitted when people ingest infectious oocysts that are present in contaminated food or water. The parasite is shed in feces and the oocysts become infectious only after environmental sporulation, so the route of transmission is through eating or drinking items that contain those mature oocysts. This explains why outbreaks are linked to raw or minimally processed produce and untreated or inadequately treated water. Direct contact with contaminated surfaces can lead to contamination of hands, but infection occurs when those oocysts are ingested, not merely from touch. Inhalation or vector-borne transmission aren’t plausible routes for this parasite.
