US Cyclosporiasis Outbreak Spreads to Over 30 States; Source Unknown

Thousands of people across more than 30 U.S. states have fallen ill due to a cyclosporiasis outbreak, with federal officials still working to pinpoint the source of the parasite. The widespread nature of the illness has raised concerns among public health officials and the public alike.

Cyclosporiasis is an intestinal illness caused by the microscopic parasite Cyclospora cayetanensis. People typically become infected after consuming food or water contaminated with the parasite's feces. Symptoms often include diarrhea, loss of appetite, weight loss, stomach cramps, nausea, and fatigue. These symptoms can persist for weeks or even months if left untreated.

While the exact source of the current outbreak remains under investigation, past outbreaks have been linked to various fresh produce, including basil, cilantro, berries, and pre-packaged salads. Health authorities are urging consumers to practice good food hygiene, including thorough washing of all fresh fruits and vegetables, even those with peels, as contamination can occur before peeling.
