Cyclosporiasis Outbreak Spreads to 31 U.S. States

A significant outbreak of cyclosporiasis, an intestinal illness characterized by diarrhea and nausea, has been identified across 31 U.S. states. Federal health authorities confirmed the widespread surge in cases this week, though the specific source of the contamination remains under active investigation. Cyclosporiasis is caused by the parasite Cyclospora cayetanensis, which is typically transmitted through contaminated food or water. Symptoms can include watery diarrhea, loss of appetite, weight loss, cramping, bloating, and fatigue. In some cases, vomiting and fever may also occur. The incubation period can range from a few days to over a week after consuming contaminated food or water. While the outbreak's origin is not yet pinpointed, common sources in previous outbreaks have included fresh produce such as basil, cilantro, raspberries, and pre-packaged salads. Public health agencies are working to identify the contaminated product or food item responsible for the current wave of infections. They are also advising the public to practice good hygiene, including thorough handwashing, and to be vigilant about food safety. Individuals experiencing symptoms are encouraged to seek medical attention and report their illness to local health departments to aid in the investigation. The Centers for Disease Control and Prevention (CDC) is monitoring the situation closely and will provide updates as more information becomes available regarding the source and extent of the outbreak.
