West Virginia health officials have confirmed an outbreak of cyclosporiasis affecting residents across several counties, with more than 50 confirmed cases reported so far. The outbreak is linked to contaminated produce, prompting urgent public health advisories.
The West Virginia Department of Health and Human Resources announced on March 15, 2024, that it is investigating a cyclosporiasis outbreak involving at least 52 confirmed cases. The cases have been identified in counties including Kanawha, Berkeley, and Jefferson. The source appears to be contaminated fresh produce, although specific items have not yet been officially identified.
Symptoms reported by patients include severe diarrhea, stomach cramps, nausea, and weight loss, consistent with known cyclosporiasis symptoms. No fatalities have been reported, and health officials are advising residents to discard any suspected produce and practice good hygiene.
Laboratory tests confirmed the presence of Cyclospora cayetanensis, the parasite responsible for cyclosporiasis, in stool samples from affected individuals. The investigation is ongoing to trace the contamination source, which could be linked to a local distributor or supplier.
Implications for Public Health and Food Safety
This outbreak highlights the ongoing risk of foodborne parasitic infections associated with fresh produce. Cyclosporiasis can cause prolonged gastrointestinal illness, especially in vulnerable populations. The investigation underscores the importance of food safety protocols and consumer awareness in preventing similar outbreaks.
Public health authorities emphasize that contaminated produce can be difficult to detect visually, and proper washing or cooking can reduce risk. The outbreak also raises concerns about supply chain monitoring and the need for stricter controls to prevent future incidents.

Background on Cyclosporiasis and Previous Outbreaks in the US
Cyclosporiasis is caused by the Cyclospora cayetanensis parasite, which is transmitted through ingestion of contaminated food or water. Outbreaks have occurred periodically in the US, often linked to imported produce such as berries, cilantro, and lettuce. The parasite is resistant to standard washing procedures, making prevention challenging.
In recent years, the CDC has reported multiple outbreaks across the country, prompting increased scrutiny of produce suppliers and food safety measures. West Virginia has experienced isolated cases in the past, but this is the first significant outbreak in the state in recent years.
“We are actively investigating the source of this outbreak and advise residents to avoid consuming any produce that might be contaminated. Our priority is to prevent further cases.”
— Dr. Lisa Montgomery, West Virginia Department of Health
Unconfirmed Source of Contamination and Scope
It is not yet clear which specific produce item or supplier is responsible for the contamination. The full scope of the outbreak, including whether it has affected other states or regions, remains under investigation. Additionally, the exact timeline of contamination is still being determined.
Ongoing Investigation and Public Health Measures
Health officials are continuing to trace the source of the contamination, with testing of produce supplies and interviews with affected individuals. They are also monitoring for new cases and will issue updated guidance as more information becomes available. Consumers are advised to wash produce thoroughly and stay informed through official channels.
Key Questions
How do people get cyclosporiasis?
People typically contract cyclosporiasis by eating contaminated fresh produce or drinking contaminated water. The parasite can be present on fruits and vegetables that are not properly washed or handled.
What are the symptoms of cyclosporiasis?
Symptoms include watery diarrhea, stomach cramps, nausea, loss of appetite, weight loss, and fatigue. Symptoms usually appear about a week after exposure.
Can cyclosporiasis be treated?
Yes, it is treatable with antibiotics such as trimethoprim-sulfamethoxazole. Patients are advised to seek medical attention if they experience symptoms.
Is it safe to eat produce now?
Public health officials recommend discarding any produce suspected of contamination and practicing good hygiene. Consumers should wash fruits and vegetables thoroughly and stay updated on official advisories.
Are there long-term health risks?
Most people recover fully with treatment. However, in immunocompromised individuals, the infection can be more severe and require longer treatment.
