A concerning outbreak of cyclosporiasis linked to the parasite Cyclospora cayetanensis has sickened at least 145 people across 20 states, with New York reporting the highest number of cases.
The infections, reported between May and June 16, have affected individuals ranging in age from 5 to 86 years old. Health officials have confirmed 20 hospitalizations so far, though no deaths have been reported. Experts are urgently investigating the source, as none of the patients reported recent international travel—the typical route for such infections.
The parasite triggers cyclosporiasis, an intestinal infection notorious for producing severe, watery diarrhea along with intense abdominal cramping, nausea, vomiting, fatigue, and other debilitating symptoms. In many cases, symptoms emerge about a week after exposure and can persist for weeks or even a month if untreated, raising risks of dehydration and prolonged discomfort.
