From the Iowa Department of Public Health Webpage:
Cyclosporiasis is a parasitic infection of the small intestine caused by the protozoa Cyclospora cayetanensis. It usually causes a watery diarrhea illness that can last anywhere from nine to 43 days if left untreated. Increasing frequency of cyclosporiasis has been reported in the United States and Canada since the mid-1980s.
Cyclosporiasis is reportable to the Iowa Department of Public Health by Iowa Administrative Code 641 IAC 1.
On average, it will take about one week after being infected with C. cayetanensis to start showing signs and symptoms. If left untreated, illness can last for a month or longer and may come back one or more times. Symptoms include, but are not limited to:
- Watery diarrhea
- Loss of appetite
- Weight loss
- Increased gas
- Stomach cramps
- Muscle aches
- Low-grade fever
