CDC reports nearly 3,000 cyclosporiasis cases across 32 U.S. states
The CDC says at least 2,944 cases of the parasite-caused intestinal infection have been confirmed in 32 states, with Michigan accounting for more than half of the total.
The Centers for Disease Control and Prevention (CDC) has confirmed 2,944 cases of cyclosporiasis in 32 states, according to data compiled from state health departments. Michigan leads with 1,562 reported infections and 44 hospitalizations, a rate roughly 31 times higher than its typical annual count of about 50 cases. New York and Ohio follow with 470 and 364 cases respectively, while Illinois and Florida each report over 100 cases.
California officials note between one and ten cases in the state. The CDC cautions that the actual number of infections is likely higher because some individuals recover without seeking medical care or being tested.
Cyclosporiasis, caused by the parasite Cyclospora cayetanensis, is typically spread through food or water contaminated with feces. Past outbreaks have been linked to imported fresh produce such as raspberries, basil, snow peas, mesclun lettuce and cilantro, though no specific source has been identified in the current surge.
"The most common symptom of cyclosporiasis is watery diarrhea with frequent and sometimes explosive bowel movements," the CDC explained, adding that nausea, vomiting, abdominal pain or bloating may also occur.
The incubation period ranges from two days to two weeks, making it challenging to pinpoint the source of infection. Treatment involves a ten-day course of the oral antibiotic trimethoprim-sulfamethoxazole. The CDC advises thorough washing of produce, removal of damaged portions, refrigeration of pre-cut items, and regular hand washing with soap and water before handling raw fruits and vegetables.
