Overview
The symptoms usually start within one week of ingestion of contaminated food and water. If left untreated, symptoms may persist for weeks and months. This infection is not life threatening and is rarely associated with complications. People living in endemic area might have asymptomatic infections.
Natural History
Following ingestion of sporulated oocysts of C. cayetanensis, the typical incubation period is about 7 days.[1][2] Cyclosporiasis commonly presents with the following symptoms:[3][1][2][4][5]
- Low-grade fever
- If a person ill with cyclosporiasis is not treated, symptoms can persist for several weeks to a month or more. Some symptoms, such as diarrhea, can return, and some symptoms, such as muscle aches and fatigue, may continue after the gastrointestinal symptoms have gone away.
- Infection is not usually life-threatening.
- Reported complications from Cyclospora infection are rare, but have included malabsorption and cholecystitis.
- Some people with Cyclospora infection experience no symptoms at all, particularly persons living in areas where the disease is endemic.
Complications
Prognosis
