What is Cyclosporiasis?
Cyclosporiasis is an intestinal illness caused by the microscopic parasite Cyclospora cayetanensis.
It spreads through food or water contaminated with human faecal matter, commonly through fresh produce exposed to contaminated irrigation water.
Symptoms include watery, sometimes explosive diarrhoea, nausea and fatigue; outbreaks typically peak during spring and summer.
The illness is rarely fatal, and most healthy individuals recover, though symptoms can persist for weeks without treatment.
Key Facts for Prelims
Cyclosporiasis became a nationally notifiable disease in the United States in 1999.
Common vehicles of infection in past outbreaks have included basil, raspberries, snow peas and lettuce, mostly imported fresh produce.
Treatment typically involves a course of antibiotics, distinguishing it from viral gastrointestinal illnesses.
The parasite is classified among protozoan pathogens, distinct from bacterial agents such as Salmonella and E. coli, which cause other common foodborne illnesses.
Unlike bacteria, Cyclospora does not multiply outside a host; contamination therefore always traces back to a faecal source at some point in the supply chain.
