Will the CDC's 2026 U.S. measles case count top 2,350 in its next weekly update? Currently at 2,318.

The CDC's weekly measles update released around July 30, 2026 showed the 2026 U.S. case count had risen to 2,371, topping the 2,350 threshold this question required and resolving it yes. The update added 53 new cases to the prior week's total of 2,318, continuing a surge that had already pushed the annual count past 2025's full-year total of 2,289 and to the highest level since 1991, the year before the U.S. was declared measles-free in 2000.

All but 16 of the new cases were locally acquired across 45 U.S. jurisdictions, with the remainder tied to international travel, and the outbreak count for the year climbed to 37. Public health officials noted that roughly 93-94% of cases were tied to ongoing outbreaks, and the vast majority of infected individuals were unvaccinated. Officials have said the sustained case count puts the U.S. at risk of losing its measles elimination status when the Pan American Health Organization reviews transmission data later in 2026. The community had assigned an 80% chance to this outcome, and the case count confirmed that expectation.
