Raleigh Durham, NC, July 29, 2026 —
Updated data from the Centers for Disease Control and Prevention (CDC) indicates that over 18,000 cases of cyclosporiasis have been reported across 45 states in the United States.
Cyclosporiasis is an intestinal illness caused by the one-celled parasite Cyclospora cayetanensis. People typically become infected by consuming food or water contaminated with the parasite.
Symptoms of cyclosporiasis can include frequent, watery bowel movements, loss of appetite, weight loss, cramping, bloating, gas, nausea, fatigue, and sometimes vomiting. Fever can also occur.
The illness is generally treated with a course of antibiotics. If left untreated, symptoms can last for several days to a month or even longer. Some individuals may experience recurrent or worsening symptoms after a period of improvement.
The CDC has been tracking cases of cyclosporiasis, which can be linked to various food sources. Investigations into the specific sources of these widespread infections are ongoing. The exact number of cases, specific states involved, and any identified outbreak sources were not detailed in the provided data update beyond the total case count and the number of states affected.
Public health officials recommend thorough handwashing with soap and water after using the toilet or changing diapers, and before eating or preparing food. Thoroughly washing fruits and vegetables under running water before eating them is also advised.
