Nationwide Outbreak: 12,000 Cyclosporiasis Cases Reported Across 40 States
A cyclosporiasis outbreak has hit 40 states, with 12,000 cases reported. The CDC is working to contain the spread. Learn more.
POLICY WIRE — Washington, D.C. — An unprecedented outbreak of cyclosporiasis, a gastrointestinal illness caused by the Cyclospora cayetanensis parasite, has now affected 12,000 individuals across 40 states, according to the Centers for Disease Control and Prevention (CDC). The agency is actively working to identify the source of the outbreak — and implement measures to halt its spread.
The first cases were reported in early June, with numbers rapidly escalating in the following weeks. The parasite, which causes explosive diarrhea and other severe gastrointestinal symptoms, is typically spread through contaminated food and water. The CDC has urged the public to practice stringent hygiene — and avoid potential sources of contamination.
“We’re treating this outbreak with the utmost urgency,” said Dr. Emily Rivers, CDC’s lead epidemiologist on the case. “Our teams are working around the clock to trace the origin — and prevent further infections.”
Health officials are particularly concerned about the rapid expansion of the outbreak, which has now reached nine additional states in the past week. The affected states include major population centers, raising the risk of further transmission.
“We’re advising all residents in affected areas to be vigilant about their food — and water sources,” Dr. Rivers added. “Boiling water — and thoroughly washing produce can significantly reduce the risk of infection.”
The CDC is collaborating with state health departments, the Food and Drug Administration (FDA), and other federal agencies to pinpoint the outbreak’s source. Preliminary investigations suggest a link to imported produce, though this hasn’t been confirmed.
“We’re examining all possible avenues, including imported goods — and domestic sources,” said FDA Commissioner Dr. Margaret Hollis. “Consumers should stay informed — and follow guidelines from trusted health authorities.”
The outbreak has prompted several states to issue public health alerts and increase surveillance for cyclosporiasis cases. Health departments are urging medical providers to report suspected cases immediately to facilitate a rapid response.
