Cyclosporiasis
Cyclosporiasis is an illness of the intestines caused by a parasite that passes from the body in the stool and enters the mouth of another person. It is spread when people swallow water or food that was contaminated with infected stool. Outbreaks have been linked to fresh fruits and vegetables imported from countries with poor water treatment systems.
