The US Centers for Disease Control and Prevention reported on the 24th that since this year, the total number of confirmed cases of measles in the US has reached 2,318, surpassing 2,289 cases in 2025. This data makes 2026 the worst measles outbreak in the US since 1991. The United States announced the elimination of measles in 2000, but the number of cases since 2025 has exceeded the total number of cases in the 25-year period from 2000 to 2024. Public health experts believe that this situation is not surprising. Vaccination rates in the US have continued to decline in recent years, and some regions with low vaccination rates will become high-risk areas for the continued outbreak and spread of measles outbreaks.
