Cyclospora transmission statement

• A. It is not commonly spread person-to-person
• B. It is primarily spread by person-to-person contact
• C. It is transmitted by water and food
• D. It is spread by airborne droplets

Answer: (A)

Cyclospora is mainly a food- and water-borne parasite. The infectious form is shed in stool, but it only becomes infectious after environmental sporulation, which makes direct person-to-person spread inefficient and uncommon. That’s why the statement that it is not commonly spread person-to-person best reflects how transmission usually occurs. Outbreaks are typically linked to contaminated produce or water, rather than close-contact transmission between people. Airborne droplets are not a known transmission route for Cyclospora.
