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 23, 2026, the Centers for Disease Control and Prevention (CDC) reports 1,792 confirmed measles cases in the United States year-to-date, with 93% outbreak-associated across 22 new outbreaks in 37 jurisdictions—primarily among unvaccinated individuals (92% of cases). Declining MMR vaccination coverage among kindergartners, now at 92.5% versus the 95% herd immunity threshold needed to curb this highly contagious virus (R0 of 12–18), has enabled sustained transmission in low-coverage pockets. Recent weeks show slowing new cases (down to seven rash onsets in the latest reporting period), but global measles surges heighten import risks during summer travel. Traders should watch weekly CDC Thursday updates, state vaccination campaigns, and epidemiological surveillance for shifts in trajectory before year-end resolution.
