History and Symptoms
Symptoms of cyclosporiasis begin an average of 7 days (range, 2 days to > 2 weeks) after ingestion of sporulated oocysts (the infective form of the parasite). Symptoms of cyclosporiasis may include:
- Watery diarrhea (most common)
- Loss of appetite
- Weight loss
- Cramping
- Bloating
- Increased gas
- Nausea
- Fatigue
Other symptoms that may occur but are less common include:
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.
