IDPH is working with local public health agencies to interview those who are sick to find out if there is a common food exposure that would indicate the source of the parasite.

Cyclospora is a parasite that has caused outbreaks in the past through fresh fruits and vegetables. Iowa public health officials believe that fresh vegetables, not fruit, may be the agent in this outbreak, through information gathered at interviews with patients.

Symptoms of cyclospora include watery diarrhea, which can last for 2 months if untreated, fatigue, loss of appetite, weight loss, bloating, increased gas, stomach cramps, vomiting, nausea, low-grade fever, and muscle aches. If you are experiencing any of these symptoms, see your health care provider and ask about a stool test. A very specific test needs to be conducted to diagnose a Cyclospora infection. This infection is reportable to public health officials. Treatment with antibiotics is prescribed.
