TL;DR
The CDC is investigating a parasitic outbreak causing severe, explosive diarrhea in multiple states. The source remains unidentified, and officials are working to determine the cause to prevent further cases.
The Centers for Disease Control and Prevention (CDC) is investigating a parasitic outbreak linked to cases of severe, explosive diarrhea reported in multiple states. This development comes amid reports from health officials about a rise in gastrointestinal illnesses with unusual symptoms, prompting urgent investigation to identify the source and prevent further cases.
According to the CDC, dozens of cases of intense diarrhea have been reported across at least five states, with some patients experiencing dehydration and other complications. The agency confirmed that laboratory testing identified the presence of cyclospora, a parasite known to cause gastrointestinal illness. The source of the infection remains unknown, but health authorities suspect contaminated food or water sources may be involved. Read about the parasite outbreak.
Health officials have not yet identified a specific food item, location, or event linked to the outbreak. The CDC has issued advisories to healthcare providers to report suspected cases and is conducting epidemiological investigations to trace potential sources. No deaths have been reported, but several patients have required hospitalization for dehydration and supportive care. Find out more about the ongoing investigation.
Why the Parasite Outbreak Matters to Public Health
This outbreak underscores the importance of food and water safety, as well as the need for rapid response to unusual illness clusters. Identifying the source is critical to prevent further infections, especially since cyclospora can be transmitted through contaminated produce or water supplies. The investigation also highlights ongoing challenges in controlling parasitic infections in the U.S. and the importance of public awareness about gastrointestinal illness symptoms.

Recent Trends in Foodborne and Waterborne Parasite Outbreaks
While cyclospora outbreaks are relatively rare, they have been linked to imported produce and contaminated water sources in past cases. The CDC notes that similar outbreaks have occurred in recent years, often associated with fresh produce such as berries or leafy greens. The current investigation follows a pattern of increased parasitic infections linked to food supply chains, raising concerns about food safety standards and pathogen monitoring.
“We are actively working to identify the source of this outbreak to prevent additional cases. Consumers should remain vigilant about food hygiene and report any severe gastrointestinal symptoms to healthcare providers.”
— Dr. Anne Miller, CDC Epidemiologist
