The CDC has released information about cyclosporiasis, an intestinal infection caused by the Cyclospora parasite that had affected 514 people in 17 states as of Aug. 8. The outbreak has led to at least 30 reported hospitalizations, but no deaths.
The states with reported cases are Iowa, Texas, Nebraska, Florida, Wisconsin, Illinois, New York (reported by the public health departments of both the state and New York City have reported cases), Georgia, Missouri, Arkansas, Connecticut, Kansas, Minnesota, New Jersey, Ohio, Louisiana and New Jersey. Of the Whether the cases in all states are part of the same outbreak is unclear, the CDC stated.
Investigations performed by the public health departments of Iowa and Nebraska indicate a link between Cyclospora infections and a prepackaged salad mix. A traceback investigation conducted by the FDA identified Taylor Farms de Mexico, a processor of salads sold to restaurants and a subsidiary of Taylor Farms of Salinas, Calif., as the source of the salad mix identified in the cyclosporiasis outbreak in Iowa and Nebraska.
The CDC will continue to work with federal, state and local partners in the investigation to determine whether this conclusion applies to the increase in cases of cyclosporiasis in other states.
Symptoms of cyclosporiasis begin anywhere from two days to two weeks after ingestion of the infective form of the parasite, and most commonly include watery diarrhea. Other possible symptoms are loss of appetite, weight loss, cramping, bloating, increased gas, nausea and fatigue. Less common symptoms are vomiting and low-grade fever.
The infection usually is not life-threatening, but symptoms may persist for several weeks to a month or more without treatment with antibiotics.
