This market will resolve to "Yes" if there have been the specified amount or more confirmed cases of Measles (Rubeola) in humans in the territory of the United States of America in 2026 according to the CDC case counter between January 1, 2026, 12:00 AM ET and December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". The resolution source for this market will be the CDC Measles (Rubeola) counter (see: https://www.cdc.gov/measles/data-research/index.html) at the resolution time. If the counter becomes unavailable, another credible source will be used. Note: Only cases reported by the CDC Measles (Rubeola) counter will qualify, regardless of reports from U.S. State agencies or other sources.As of April 2, 2026, the CDC reports 1,671 confirmed measles cases across 33 U.S. jurisdictions, with 94% outbreak-associated amid 17 new outbreaks this year—primarily in unvaccinated communities where 92% of patients lack documented MMR vaccination or have unknown status. This surge, surpassing 2025's early pace (full-year total: 2,286 cases), stems from kindergarten MMR coverage dipping to 92.5%—below the 95% herd immunity threshold—and rising global importations. Hospitalizations stand at 5% (91 cases), with no fatalities to date. Weekly CDC surveillance updates, reflecting cases by rash onset, will gauge containment via public health responses and vaccination uptake, key variables for the year's total.
