Cyclosporiasis

Cyclospora cayetanensis is a parasite that causes cyclosporiasis. Most people who become ill with cyclosporiasis get watery diarrhea, loss of appetite, weight loss, stomach cramps/pain, bloating, gas, nausea and fatigue within one week after exposure to the organism. This illness can last from a few days, to a month or longer if not treated. Symptoms may go away and then return one or more times. Most cases of cyclosporiasis are associated with consuming contaminated food or water. In the United States, foodborne outbreaks of cyclosporiasis have been linked to imported fresh produce, including raspberries, basil, snow peas and mesclun lettuce. Persons with travel to tropical and subtropical countries may be at higher risk of consuming contaminated food or water.
