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.**An unprecedented 2026 cyclosporiasis season driven by a large multistate outbreak linked to processed iceberg lettuce has produced 15,716 laboratory-confirmed domestically acquired cases as of August 17, according to CDC surveillance data, with 828 hospitalizations and 2 deaths reported across 47 states plus D.C. and Puerto Rico.** This already dwarfs the 1,180 cases recorded for the entire May 1–August 31, 2025 season and far exceeds typical annual totals of roughly 3,000. CDC is also tracking at least 11,841 additional reports requiring further investigation, while investigating multiple clusters including the dominant lettuce-linked outbreak traced to central Mexico sources and several others without confirmed vehicles. Illness onsets cluster around a July 7 median, consistent with the parasite’s seasonal pattern tied to warmer months and contaminated fresh produce; new confirmations continue but state-level processing backlogs suggest the sharpest rise may be easing. CDC updates case counts on an ongoing basis, with final seasonal totals typically compiled shortly after August 31, when the official surveillance window closes. Traders should monitor any late-August CDC or state health department releases for final adjustments to the confirmed tally, as underreporting and diagnostic variability remain inherent to Cyclospora surveillance.
