Event Summary

The United States is experiencing its worst measles outbreak in 35 years, with 2,318 confirmed cases in 2026 as of July 24, surpassing the 2025 total of 2,289 cases. The surge is attributed to declining vaccination rates and growing vaccine hesitancy, exacerbated by Health Secretary Robert F. Kennedy Jr.'s anti-vaccine stance. The CDC reports that 93% of cases are in unvaccinated individuals, and outbreaks have occurred in 45 states. The World Health Organization is reviewing the US's measles elimination status, which could be lost. Experts warn the outbreak will worsen and may lead to resurgence of other vaccine-preventable diseases.
