As of March 26, 2026, the CDC reports 1,575 confirmed measles cases across 32 U.S. jurisdictions, with 16 new outbreaks accounting for 94% of cases—far exceeding early-year totals from prior seasons and approaching 70% of 2025's full-year 2,285 cases. Most infections (92%) occur in unvaccinated individuals amid declining MMR vaccination coverage, with kindergarten rates at 92.5% for the 2024–2025 school year, below the 95% herd immunity threshold needed to prevent community transmission (R0 of 12–18). Global surges heighten importation risks via travel. Traders should monitor weekly CDC surveillance updates and Morbidity and Mortality Weekly Reports for ongoing trajectories, potential containment via vaccination drives, and year-end totals.
