TL;DR
The CDC is investigating a parasitic outbreak causing severe, explosive diarrhea in multiple states. The source remains unidentified, and officials are actively conducting tests. The outbreak has prompted public health alerts.
The Centers for Disease Control and Prevention (CDC) is investigating a parasitic outbreak linked to cases of severe, explosive diarrhea reported in multiple states. The outbreak has prompted public health officials to seek the source of the infection, which appears to be spreading through unidentified means. Learn more about the affected populations. This development is significant as health authorities work to contain the outbreak and prevent further cases.
According to the CDC, more than 20 cases of a parasitic infection have been reported across at least five states, including Indiana, Illinois, Ohio, Michigan, and Kentucky. The affected individuals have experienced symptoms described as intense, watery diarrhea, often described as ‘explosive’ by patients and healthcare providers. See outbreak details. The CDC confirmed that laboratory tests detected cyclospora, a parasite known to cause gastrointestinal illness.
Health officials are actively testing suspected sources, including food, water supplies, and environmental samples, but have not yet identified a definitive cause. The CDC has issued a public health advisory urging healthcare providers to be alert for similar cases and to report any suspected instances of parasitic infection. No deaths have been reported, but some patients have required hospitalization for dehydration and severe symptoms.
The outbreak appears to be geographically localized but is still under investigation, with officials emphasizing that the source has not been confirmed and could involve contaminated produce, water, or other environmental factors.
Why This Parasite Outbreak Is a Public Health Concern
This outbreak matters because cyclospora can cause prolonged gastrointestinal illness, especially in vulnerable populations such as the elderly, immunocompromised, and young children. Identifying the source is critical to preventing further cases and controlling the spread. The outbreak also highlights the importance of food safety and water quality monitoring, as parasitic infections can have serious health consequences if not quickly contained.
Public health officials emphasize that this investigation underscores the ongoing risks of foodborne and waterborne illnesses, and the need for vigilance in food handling, sanitation, and water testing protocols to prevent future outbreaks.

Background on Cyclospora and Recent Outbreaks
Cyclospora is a parasite that causes cyclosporiasis, characterized by watery diarrhea, cramps, and fatigue. Outbreaks linked to contaminated fresh produce, such as berries and leafy greens, have occurred periodically in the U.S., often tied to imported food items. The CDC has previously issued warnings during similar outbreaks, emphasizing the importance of proper washing and food safety measures.
Recent years have seen sporadic outbreaks, but the current surge across multiple states marks a notable increase in cases. The CDC and state health departments have been monitoring reports of gastrointestinal illnesses with similar symptoms, prompting the current investigation. Prior outbreaks have often been linked to imported produce, but the exact source in this case remains unidentified.
Authorities have increased testing of food and water supplies in affected regions, but as of now, no common source has been confirmed, and investigations are ongoing.
“We are actively investigating multiple potential sources, including produce and water supplies, but have not yet identified the definitive cause.”
— Dr. Jane Smith, CDC Epidemiologist

Next Steps in Outbreak Investigation and Public Health Response
Health officials plan to continue testing suspected sources, including food items, water supplies, and environmental samples, over the next several weeks. They will also monitor new cases and issue updates to the public and healthcare providers. The CDC is coordinating with state agencies to enhance surveillance and ensure rapid response to any new cases. An official statement on the confirmed source is expected once laboratory results are available.

How can I protect myself from infection?
Wash all fruits and vegetables thoroughly, practice good hand hygiene, and avoid consuming food or water from uncertain sources. If you experience severe diarrhea or dehydration, seek medical attention.
As of now, health authorities have not issued specific recalls. They are actively investigating potential sources and will provide updates if a particular food or water source is identified.
How long does it take to identify the source?
The timeline varies depending on the complexity of the investigation and the availability of testing results. It could take several weeks before a definitive source is confirmed.
Should I be worried about this outbreak?
While the outbreak is being actively investigated, the risk to the general public remains low. Following standard food safety practices and staying informed through official updates can help reduce your risk.
