Ongoing measles transmission in the United States, driven by multiple large outbreaks with 94% of cases linked to community spread, is the main factor shaping trader views on cumulative 2026 totals by August 31. CDC data through August 6 report 2,465 confirmed cases—already exceeding the full-year 2025 total of 2,289—with 38 new outbreaks this year and 20% of cases in children under 5. Most infections occur among unvaccinated individuals in clusters with sub-optimal MMR coverage, sustaining chains of transmission across 47 jurisdictions. Recent weekly additions of roughly 94 cases indicate continued momentum into mid-August. Weekly CDC surveillance releases and state health department reports through late August represent key upcoming data points that could shift the trajectory before the market resolves.
