The United States is experiencing a significant outbreak of cyclosporiasis, a parasitic infection caused by Cyclospora cayetanensis. As of July 15, 2026, the Centers for Disease Control and Prevention (CDC) reports over 1,200 confirmed cases across 33 states, with hospitalizations in 15% of cases. The outbreak is linked to imported fresh produce, including cilantro and raspberries, though the exact source remains under investigation.
Symptoms include watery diarrhea, nausea, cramping, and fatigue, lasting weeks if untreated. The CDC advises washing produce thoroughly and seeking medical attention for persistent gastrointestinal distress. No deaths have been reported, but the outbreak is expected to grow as summer travel and produce consumption increase.
Health officials emphasize that cyclosporiasis is treatable with antibiotics, typically trimethoprim-sulfamethoxazole. The CDC continues to monitor the situation and update guidance for healthcare providers and the public.
