Cyclosporiasis history and symptoms

Symptoms of cyclosporiasis begin 7 days following ingestion of water and food contaminated with sporulated oocysts. The most common symptom is watery diarrhea. Other symptoms include loss of appetite, cramping, flatulence, fatigue, low-grade fever, nausea and vomiting.

• The average incubation period for cyclospora is 1 week, but symptoms may appear from 1 to 14 days after ingestion of sporulated oocysts.
• Symptoms typically manifest as watery diarrhea, which can be severe.
• Patients might recall eating fresh vegetables, such as lettuce, basil, or cilantro. ^[1]
• Patients must be asked if they have traveled to a region where the protozoan is endemic, such as countries in the tropics and subtropics. ^[2]
• Untreated infections typically last for 10-12 weeks.
• For untreated patients, diarrhea and other symptoms may relapse.
• A more severe form of the disease can occur in immunocompromised patients such as those with AIDS.

Patients with cyclosporiasis may remain asymptomatic, specially in persons that live in an endemic area.
