Tampa St. Petersburg, FL, July 21, 2026 —

Health officials across the United States are responding to a widespread outbreak of cyclosporiasis, with reported cases now exceeding 1,000 nationwide. The exact source of the current outbreak remains undetermined, prompting ongoing investigations by public health agencies.

Cyclosporiasis is an intestinal illness caused by the microscopic parasite Cyclospora cayetanensis. It is typically transmitted to people through contaminated food or water. Symptoms often include diarrhea, loss of appetite, weight loss, stomach cramps, bloating, increased gas, nausea, fatigue, and sometimes vomiting. A low-grade fever may also occur. The illness can affect anyone, regardless of age, but is often more severe in individuals with weakened immune systems.

The Centers for Disease Control and Prevention (CDC) and state health departments are actively working to identify common factors among those infected, such as specific food items consumed or locations visited. These investigations are crucial for pinpointing the origin of the parasite and implementing measures to prevent further spread.

While the number of reported cases has surpassed 1,000, public health authorities are urging individuals who experience symptoms consistent with cyclosporiasis to seek medical attention. Early diagnosis and treatment can help alleviate symptoms and prevent complications. Treatment typically involves a course of antibiotics.

The timeline for identifying the source of the outbreak has not yet been established. Health officials are advising the public to practice good hygiene, including thorough handwashing, and to be diligent about food safety practices. Further updates on the investigation are expected as more information becomes available.
