Cyclospora is a parasite that causes a diarrheal illness called Cyclosporiasis. Cyclospora is found in many countries, but is most common in tropical and subtropical regions. People can become infected by consuming food or water contaminated with feces that contains the parasite. It is not spread directly from one person to another.
Foodborne outbreaks have been linked to various types of fresh produce, including raspberries, basil, cilantro, snow peas, and mesclun and romaine lettuce.
Signs and Symptoms
- Watery diarrhea
- Stomach cramps
- Loss of appetite
- Weight loss
- Slight fever
- Nausea
- Fatigue
Symptoms usually begin anywhere from two days to two weeks after exposure to the parasite. Symptoms can last for several weeks to months. Symptoms may come and go in cycles, in which you seem to get better for a few days and then feel worse again.
Treatment
The infections can be treated with the antibiotic trimethoprim/sulfamethoxazole. No highly effective alternative antibiotic has been identified yet for patients who do not respond to the standard treatment or have a sulfa allergy. Diarrhea should be managed by drinking plenty of flids to prevent dehydration.
Contact your healthcare provider to discuss treatment options.
Minimizing Risk
- Avoid food or water that may have been contaminated with feces.
- Follow any food recalls and use proper food safety practices.
- Use caution when traveling to countries with minimal water treatment and sanitation systems such as avoiding tap water, fountain drinks, ice, and raw foods like fresh produce.
REMEMBER: Washing of produce, or routine chemical disinfection or sanitizing methods are unlikely to kill Cyclospora.
