    ### Instruction:
    Who is at risk for Parasites - Cyclosporiasis (Cyclospora Infection)? ?
    ### Response:
    People become infected with Cyclospora by ingesting sporulated oocysts, which are the infective form of the parasite. This most commonly occurs when food or water contaminated with feces is consumed. An infected person sheds unsporulated (immature, non-infective) Cyclospora oocysts in the feces.
