What is Cyclospora?
Cyclospora is a small parasite. Current knowledge about this parasite is limited. The first outbreak recognized in the United States occurred in 1990 and was associated with tap water from one particular building in Chicago, Illinois. Outbreaks in developing countries have also been associated with drinking water.
How is Cyclospora spread?
Little is known about how Cyclospora is spread. Cyclospora does not appear to be spread through direct person-to-person contact. Previous outbreaks have implicated contaminated water.
What are the symptoms of Cyclospora?
Symptoms may appear anywhere from one day to 2 weeks after infection with this parasite. The symptoms include a watery diarrhea, fatigue, loss of appetite, abdominal cramps, and low-grade fever. Untreated the diarrhea has been reported to last up to 70 days. The symptoms frequently come and go in a distinct cycle for several weeks. The symptoms in persons with a poorly functioning immune system may be more severe and last longer.
What should you do if you suspect you have a Cyclospora infection?
See your doctor. Since the routine stool examination used for most parasites cannot detect Cyclospora, a stool specimen should be examined using special stains for this parasite (the acid fast stain). It is important for persons with a poorly functioning immune system to seek medical attention early in the course of their illness.
What is the treatment for Cyclospora?
Over-the-counter medications have not been shown to shorten the duration of illness. Several antibiotics have been tried with varying success. Sulfa drugs seem to be the most effective in reducing the severity and duration of the illness.
