Otherwise, this market will resolve to \"No\".\n\nThe resolution source for this market will be the CDC Measles (Rubeola) counter 'Total Cases' in 2026 (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.\n\nNote: Only cases reported by the CDC Measles (Rubeola) counter will qualify, regardless of reports from U.S. State agencies or other sources.",

"context_description": "As of April 23, 2026, the CDC reports 1,792 confirmed measles cases in the United States for the year, with 93% outbreak-associated across 22 new outbreaks and prior ones spanning 37 jurisdictions, primarily Utah (over 600 cases in its ongoing outbreak), South Carolina, Texas, and Arizona. About 92% of cases occurred in unvaccinated or unknown-status individuals amid MMR coverage below the 95% herd immunity threshold, fueled by importations and community transmission in under-vaccinated pockets. Recent weekly cases dropped to seven (rash onset week of April 19), signaling slowing growth, though reporting lags could add a handful by April 30 resolution. Traders should watch state health dashboards and the next CDC update, expected early May, for final tallies amid inherent surveillance uncertainties.",
