As of August 20, 2026, the CDC has confirmed 2,777 measles cases in the United States, already exceeding the full-year 2025 total of 2,289 and marking the highest annual figure since the early 1990s. Primary drivers include 36 ongoing outbreaks, with 94% of cases linked to sustained transmission in under-vaccinated communities, particularly among children, alongside imported cases from international travel. Recent weekly surveillance shows accelerating spread, including 211 new confirmations in the latest update, reflecting low MMR coverage and carryover from 2025 clusters. Traders monitor CDC's weekly reports and MMWR publications for shifts in case counts, outbreak resolution, or vaccination trends that could influence year-end totals.
