RALEIGH — North Carolina health officials have confirmed 307 cases of cyclosporiasis and 13 hospitalizations from May 1 through July 14, the state Department of Health and Human Services reported, as dozens of other states also note rising numbers of the intestinal infection.
What officials are finding
State investigators said they have not yet identified a single contaminated product causing the increase in cases within North Carolina and that most infections do not share an obvious common source. The Department of Health and Human Services is working to trace exposures and to determine whether any links to out-of-state outbreaks exist.
Cyclosporiasis is caused by the parasite Cyclospora cayetanensis, which is typically transmitted through food or water contaminated with fecal matter. Symptoms commonly include frequent, watery diarrhea — sometimes described as "explosive" — along with abdominal cramping, bloating, fatigue, loss of appetite, weight loss, gas and nausea. The incubation period is usually about one week after exposure.
Prevention and treatment
Public health and food-safety guidance emphasizes that cyclospora often contaminates fresh produce and herbs — items not routinely killed by heat — which makes prevention more challenging than with many other foodborne illnesses. There is no vaccine. Antibiotics can treat the illness when diagnosed.
- Wash hands thoroughly with soap and water before preparing or eating food.
- Wash produce under running water; although washing may not remove all parasite contamination, it reduces risk.
- Follow food-safety practices for storage and preparation, and be cautious with uncooked fresh herbs and salad mixes.
- Seek medical care if you have persistent watery diarrhea, especially if it is severe or accompanied by dehydration.
| Metric | Reported (May 1–July 14) |
|---|---|
| Cases | 307 |
| Hospitalizations | 13 |
The state noted that, to date, most North Carolina cases do not appear to be part of a single outbreak with a common exposure point. Health officials continue interviews and laboratory testing to identify potential links and sources. Meanwhile, clinicians are reminded to consider cyclospora when patients present with prolonged watery diarrhea and to order appropriate testing.
People who develop symptoms are urged to contact their health care provider. Treatment typically involves specific antibiotics; public health authorities recommend following clinical guidance for testing and management.
As investigators work to trace exposures, consumers and food establishments are advised to adhere strictly to food-safety protocols and to report suspected food-related illnesses to local health departments.
The evolving situation will be monitored by state and federal agencies as more information becomes available.
