As health officials continue to monitor cases of cyclosporiasis across the country, Saint Mary's Regional Health System is encouraging community members to learn the signs and symptoms of the illness and take steps to reduce their risk.
Cyclosporiasis is an intestinal illness that develops after a person consumes food or water contaminated with Cyclospora cayetanensis, a microscopic parasite. The illness is not typically life-threatening, but it can cause significant gastrointestinal symptoms and may last for days or even weeks if left untreated.
Common symptoms of cyclosporiasis include:
Watery diarrhea
Stomach cramps
Nausea
Loss of appetite
Fatigue
Bloating
Increased gas
Weight loss
Symptoms usually begin about one week after a person becomes infected, although the timing can vary. Some individuals may experience symptoms that improve and then return later.
In the United States, outbreaks of cyclosporiasis have been linked to various types of fresh produce, including herbs, leafy greens, berries and pea pods. The illness spreads when contaminated food or water is consumed. Direct person-to-person transmission is considered unlikely because the parasite requires time in the environment before it can infect another person.
"While cyclosporiasis is relatively uncommon, it is important for individuals to be aware of the symptoms and seek medical attention if they experience persistent gastrointestinal illness," said Heather Jones, APRN at Saint Mary's Regional Health System.
The Centers for Disease Control and Prevention recommends following safe food-handling practices, washing hands before and after handling fresh produce, and thoroughly rinsing fruits and vegetables under running water before eating, cutting or cooking them. Consumers should also stay informed about food recalls and public health advisories.
Individuals experiencing persistent diarrhea, dehydration or other concerning symptoms should contact a healthcare provider. Healthcare professionals can diagnose cyclosporiasis through specialized laboratory testing and recommend appropriate treatment.
Saint Mary's Regional Health System remains committed to providing trusted health information and encouraging preventive measures that support the health and well-being of the River Valley community.
