As of mid-August 2026, the CDC reports 2,566 confirmed U.S. measles cases year-to-date, already surpassing the full-year 2025 total of 2,289 and marking the highest annual figure since 1991. Primary drivers include 38 new outbreaks with 94% of cases outbreak-associated, concentrated among unvaccinated populations in multiple jurisdictions, alongside sustained transmission from late-2025 clusters. This trajectory reflects declining routine immunization coverage and importations, with weekly CDC surveillance updates and an ongoing elimination-status review by the CDC advisory committee representing key near-term data points that could shift trader assessments of final 2026 totals.
