What is Cyclospora?

Cyclospora cayetanensis is a parasite composed of one cell, too small to be seen without a microscope. This parasite causes an intestinal infection called cyclosporiasis.

How is Cyclospora spread?

Cyclospora is spread by people ingesting something - such as food or water - that was contaminated with feces (stool). Cyclospora needs time (days to weeks) after being passed in a bowel movement to become infectious for another person. Therefore, it is unlikely that Cyclospora is passed directly from one person to another.

The number of people reporting a food-borne intestinal illness believed to have come from a contaminated vegetable has climbed to 62 cases in Nebraska, including 37 in Douglas County.

The Nebraska cases of cyclosporiasis are likely linked to Iowa, where 109 people in 31 counties were confirmed sick as of Thursday.

Public health officials say the illness, which causes prolonged diarrhea, is rare. It comes from eating food or drinking water contaminated with feces containing the cyclospora parasite.

Officials say the illnesses began in June, leading them to believe whatever produce caused it may have been eaten or thrown away by now.
