This market will resolve to "Yes" if there have been the specified amount or more confirmed domestically acquired cases of cyclosporiasis in humans in the territory of the United States of America since May 1, 2026, according to the CDC surveillance count by August 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". The resolution source for this market will be the CDC Surveillance of Cyclosporiasis page’s “U.S. cases reported to CDC” count (see: https://www.cdc.gov/cyclosporiasis/php/surveillance/index.html) at the resolution time. If the counter becomes unavailable, another credible source will be used. Note: Only cases reported by the CDC as confirmed domestically acquired cases of cyclosporiasis will qualify, regardless of reports from U.S. State agencies or other sources. Travel-associated cases acquired outside the United States will not qualify.The unprecedented 2026 cyclosporiasis season, with 17,180 laboratory-confirmed domestically acquired U.S. cases reported to CDC through August 24—versus just 1,180 by the same date in 2025—has been propelled by a large multistate outbreak tied to processed iceberg lettuce from central Mexico plus at least six additional clusters under joint CDC-FDA investigation. Most illnesses show median onset in early July, with recent data indicating a slowing incidence in hard-hit states like Michigan. Cyclospora transmission via contaminated fresh produce peaks in warmer months; the official surveillance window closes August 31, after which final case counts and any remaining laboratory confirmations will determine market resolution amid known reporting lags and underdiagnosis.
