**Elevated 2026 cyclosporiasis incidence driven by a multistate outbreak.** CDC surveillance data show 15,716 laboratory-confirmed domestically acquired cases since May 1, versus 1,180 for the comparable 2025 period, with additional unconfirmed reports exceeding 11,000. A large cluster linked to iceberg lettuce imported from central Mexico accounts for over 10,930 illnesses across 17 states, with illness onsets extending into early August. Cyclospora transmission peaks seasonally with fresh produce consumption; ongoing case reporting and potential underdiagnosis mean totals through August 31 will reflect continued surveillance updates from CDC and state health departments. Market-implied odds hinge on whether cumulative confirmed cases cross key thresholds before the cutoff, with near-term model refinements or new cluster identifications able to shift counts.
