Public health officials suspect fresh vegetables, not fruit, are the source of the outbreak of a parasitic infection that so far has sickened at least 80 people in Nebraska and Iowa.
Interviews with the people who have become ill with the cyclospora infection are continuing, officials said.
Almost all of those with the illness reported first becoming sick in mid-June, and at least one person has been hospitalized, Iowa officials said. One of the Nebraskans with the illness also was hospitalized. Twenty-five of the 35 Nebraskans are from Douglas County, Nebraska officials said.
It usually takes a week after exposure to develop the illness, officials said, but it can take up to two weeks. People with the illness can experience watery diarrhea, fatigue, a lack of appetite, nausea, abdominal cramping, low-grade fever and weight loss. The illness can persist for nearly two months.
Physicians are encouraged to test for cyclospora if a patient has had diarrhea lasting more than a couple of days and if the illness is accompanied by a severe lack of appetite or fatigue. The illness can be treated with a simple antibiotic if the parasite is properly identified.
