Public Health Officials Monitor Rising Parasitic Infections
Local health officials in Buncombe County have confirmed four cases of cyclosporiasis, an intestinal illness caused by the Cyclospora cayetanensis parasite. This report follows a broader surge in infections across North Carolina, where the Department of Health and Human Services (NCDHHS) has documented 307 cases and 13 hospitalizations between May 1 and July 14, 2026.
Neighboring Henderson County has also reported seven confirmed cases since July 2. While the illness is generally not life-threatening, it can cause severe gastrointestinal distress and poses a higher risk to vulnerable populations, including the elderly and immunocompromised individuals.
Understanding the Infection
Cyclosporiasis is a foodborne illness typically transmitted through the consumption of food or water contaminated with feces. The Centers for Disease Control and Prevention (CDC) notes that the infection is frequently associated with fresh produce, specifically herbs like cilantro and parsley. Symptoms usually appear about one week after exposure and include watery, sometimes “explosive” diarrhea, bloating, stomach cramping, nausea, and fatigue.
State and local health departments, including those in Buncombe and Henderson counties, are currently conducting investigations to identify the source of the outbreak. To date, no specific food product has been identified as the culprit, and officials confirmed that the North Carolina cases have not been linked to outbreaks in other states.
Prevention and Food Safety
Health experts emphasize that while trace-back investigations are complex, the public can mitigate risks by adhering to rigorous food safety protocols. The NCDHHS recommends the following measures for handling fresh produce:
- Wash hands thoroughly for at least 20 seconds with warm water and soap before and after handling food.
- Scrub firm fruits and vegetables with a clean brush under running water, even if labeled “prewashed.”
- Remove the outer leaves of lettuce and cabbage heads.
- Refrigerate cut, peeled, or cooked produce within two hours.
The NCDHHS continues to maintain a statewide dashboard that is updated weekly to track current case counts. Individuals experiencing symptoms are encouraged to consult their healthcare providers, as the infection can be effectively treated with specific antibiotics.
