DES MOINES – The Iowa Department of Public Health, CDC and local public health agencies are investigating an outbreak of an intestinal illness caused by Cyclospora (a rare parasite). As of today, July 12, 45 cases of Cyclospora infections have been reported to IDPH; almost all have been identified through testing at the State Hygienic Lab (SHL), including:
Linn County – 21 cases
Fayette County – 3 cases
Polk County – 3 cases
O’Brien County – 3 cases
Dallas County – 2 cases
Mills County – 2 cases
Webster County – 2 cases
Des Moines County – 2 cases
Benton County – 1 case
Black Hawk County – 1 case
Buchanan – 1 case
Johnson County – 1 case
Pottawattamie County – 1 case
Van Buren County – 1 case
Woodbury – 1 case
Cyclosporiasis illness occurs when an individual consumes food or water contaminated with the parasite. Fresh fruits and vegetables are typically associated with Cyclospora outbreaks. While the source of this outbreak has not been determined, the investigation, which includes epidemiological interviews with those who have been ill, indicates fresh vegetables, not fruit, are implicated as a likely source.
Most people’s illness began in mid to late June and at least one person has been hospitalized. Many people report still being ill with diarrhea and some have had relapses. Specific treatment is available (but it is not typically used for more common diarrheal illnesses). Also, very specific laboratory testing (not commonly ordered) must be done to detect Cyclospora.
Additional cases have been identified in Nebraska and other Midwestern states. IDPH is coordinating the investigation with public health officials in those states. Washing fresh produce is recommended; however, it can be very difficult to wash Cyclospora off all types of produce.
Cyclosporiasis causes a watery diarrhea that lasts an average of 57 days if untreated. Other symptoms include:
Fatigue (severe tiredness)
Loss of appetite
Weight loss
Bloating
Increased gas
Stomach cramps
Nausea
Vomiting
Muscle aches
Low-grade fever
