Nearly 400 cyclosporiasis cases confirmed in NY as officials probe nationwide outbreak

Rochester, N.Y. - Health officials are investigating an outbreak of a foodborne parasite that has sickened hundreds of people nationwide, including nearly 400 in New York since May. Cyclosporiasis, an intestinal illness often linked to contaminated fresh produce, can cause symptoms such as severe diarrhea and vomiting. No cases have been confirmed in the Rochester area. Most of the state's infections have been reported in New York City, with the remainder scattered across the state. Michigan has recorded more than 1,000 cases, while Ohio has confirmed more than 800, making them the hardest-hit states at this time. The New York State Department of Health said it is working with the Centers for Disease Control and Prevention, the Food and Drug Administration and local health departments to identify possible sources of exposure. BACKGROUND: A gut-wrenching mystery: CDC hunts source of 'explosive' diarrhea outbreak "During these investigations, if someone is a confirmed case, the Department of Health asks them to list the foods they purchased and ate so investigators can determine whether there are common links among cases," said Dr. MaryRose Laguio-Vila, infectious disease specialist for Rochester Regional Health. Cyclospora infections typically increase during the summer months, and doctors say most otherwise healthy people recover on their own. They advise anyone whose symptoms last more than several days or who shows signs of dehydration to contact a healthcare provider. Click here to learn more about the infection and how to prevent it.
