The CDC is tracking a surge in cyclosporiasis, an intestinal illness caused by the Cyclospora parasite. Officials have counted 190 cases between May 1 and June 16 across 17 states, Florida included. Most people got sick within the United States, and no one has traced the outbreak to a specific food yet. That leaves a big question mark, but experts warn people to handle fresh produce carefully and see a doctor if they feel sick.
Nationwide, 145 of these cases had no link to international travel, all beginning between May 1 and June 6, 2026. Florida’s seen between one and ten cases so far, according to the CDC’s map. At least 20 people have needed hospital care, but no deaths have occurred.
Cyclosporiasis isn’t rare enough to go unnoticed, as healthcare providers must report every confirmed case to their local health department. It’s notifiable in nearly every state, plus D.C. and New York City. If someone has persistent stomach issues, diarrhea, cramping, or fatigue, doctors should test for Cyclospora and inform public health authorities.
Looking at the numbers, those affected range from five to eighty-six years old, with the median age at 42. Around 61% are women. Most symptoms began in mid-May. The CDC says case numbers typically spike during spring and summer, from May through August, though off-season clusters sometimes pop up.
While investigators dig into potential sources of the outbreak, the CDC and the FDA haven’t identified a specific food or supplier yet. Clusters in multiple states are under active investigation.
In addition to U.S.-linked cases, there have been 45 situations tied to travel. People got sick after eating or drinking contaminated food or water outside the U.S. These folks ranged in age from 17 to 89, with three hospitalizations and no deaths.
If you or someone you know starts feeling the typical symptoms of cyclosporiasis, reach out to a healthcare provider quickly. Treatment works, and early reporting helps to spot and stop clusters before they grow. For now, be scrupulous with fresh fruits and vegetables, and stay mindful of any stomach issues that linger.
