US Cyclospora Outbreak Doubles: What You Need to Know

The number of confirmed Cyclospora infections across the United States has nearly doubled, with the Centers for Disease Control and Prevention (CDC) reporting 1,645 cases in 34 states as of July 14, 2026. This surge has resulted in 141 hospitalizations, though no deaths have been associated with the current outbreak. Health authorities are also reviewing over 5,100 additional potential cases.
Cyclosporiasis, the illness caused by the parasite, typically manifests with watery diarrhea, loss of appetite, fatigue, and abdominal cramping. While most infected individuals can recover at home with prompt treatment, including antibiotics and hydration, severe symptoms like significant dehydration or persistent vomiting necessitate emergency care.
The precise source of the outbreak remains unidentified, although past U.S. Cyclospora outbreaks have been linked to contaminated fresh produce. Investigators from the CDC, FDA, and state health departments are actively working to pinpoint the source, but no recalls have been issued. Cases typically peak during spring and summer months.
