CDC Investigates Cyclospora Outbreak Sickening Over 400

A Cyclospora outbreak has sickened more than 400 people across four states, with investigators from the Centers for Disease Control and Prevention (CDC) actively searching for the source of the contamination. The CDC indicated on May 16, 2024, that the actual number of infections is likely significantly higher than the reported cases. The agency is urging individuals experiencing symptoms to seek medical attention promptly.

Cyclosporiasis is an intestinal illness caused by the microscopic parasite Cyclospora cayetanensis. Symptoms typically appear about a week after ingesting the parasite and can include watery diarrhea, loss of appetite, weight loss, cramping, bloating, and fatigue. Some individuals may also experience nausea, vomiting, and fever. The illness is often treated with antibiotics, and most people recover fully, though symptoms can recur.

Outbreaks of Cyclospora are often linked to contaminated produce, particularly fresh herbs and berries, which can become contaminated through contact with contaminated water or soil. The CDC is collaborating with state and local health departments to identify the specific food item or items responsible for this current outbreak. This investigation involves detailed interviews with affected individuals to pinpoint common exposures.

While the exact source remains unidentified, the CDC's ongoing investigation aims to prevent further cases by identifying and removing contaminated products from the market. Public health officials emphasize the importance of thorough handwashing and proper food preparation techniques to minimize the risk of infection. The agency has not yet released specific details about the states involved or the timeline of the outbreak's onset.
