WNC -- July 11. 2026: Confirmed cases of cyclosporiasis have emerged in Western North Carolina, including one case in Buncombe County, as state health officials monitor more than 200 cases reported statewide since late spring. This intestinal illness, caused by the Cyclospora parasite, prompts officials to urge WNC residents to take precautions, particularly concerning fresh produce and hygiene.
The confirmed cases in Western North Carolina include one in Buncombe County, three in Henderson County, two in McDowell County, and one in Rutherford County. These local infections are part of a broader increase in cyclosporiasis across North Carolina, which has seen over 200 reported infections across 28 counties. While Wake County has the highest numbers in the state, WNC residents are clearly affected by the statewide trend.
Cyclosporiasis is an intestinal infection caused by the microscopic parasite Cyclospora cayetanensis. People become infected by eating or drinking food or water contaminated with feces containing Cyclospora. The illness is frequently linked to contaminated fresh produce, especially herbs, vegetables, berries, and leafy greens, which are often served uncooked.
Symptoms typically include watery or severe diarrhea, stomach cramps, abdominal pain, nausea, loss of appetite, weight loss, and fatigue. These symptoms usually begin about a week after exposure and can last from a few days to a month or longer, sometimes returning after initially subsiding. While not usually life-threatening, the illness can be debilitating due to severe diarrhea and dehydration. Nationally, 20 hospitalizations have been reported among U.S.-acquired cases, but no deaths have occurred in the current surge. Local clinicians in WNC note that many cases improve within several days, but persistent, severe, or worsening symptoms warrant medical attention.
Prevention: What WNC Residents Should Do
State health officials and the Centers for Disease Control and Prevention (CDC) recommend several practical steps for residents to reduce their risk of infection, especially given the confirmed cases in WNC.
Handle and Wash Fresh Produce Carefully: Always wash hands with warm water and soap for at least 20 seconds before and after handling fresh fruits, vegetables, or herbs. Rinse produce thoroughly under running water before peeling to avoid transferring contaminants. Gently rub produce while rinsing, and use a clean vegetable brush for firm items like melons and cucumbers. Drying produce with a clean cloth or paper towel can help reduce microbes. It is also advisable to remove the outer leaves of lettuce or cabbage heads and cut away bruised or damaged areas. Officials caution that while washing reduces the parasite, it may not eliminate Cyclospora entirely, as it can adhere strongly to produce surfaces.
Consider Cooking When Possible: Cooking is considered the only reliably effective way to kill Cyclospora. When practical, cooking vegetables or herbs that may be higher risk is recommended, particularly for individuals who are older, immune-compromised, or have chronic health conditions.
Practice Good Hygiene: Always wash hands after using the bathroom and before eating. Individuals experiencing diarrhea or gastrointestinal illness should avoid preparing food for others.
If symptoms consistent with cyclosporiasis develop, residents should contact a healthcare provider. Diagnosis involves stool testing, and specific antibiotics are available for treatment, though supportive care with rest and fluids is also important to prevent dehydration.
