US Measles Cases Reach 33-Year High Across 38 States

The United States is experiencing the highest number of measles cases in over three decades, with nearly 1,300 confirmed cases reported in 2025, surpassing previous records since 1992. The outbreak has spread across 38 states and Washington D.C., with Texas accounting for more than 700 cases. Most cases have occurred among unvaccinated individuals, with children under 5 years old being the most affected and hospitalized group. Despite three deaths this year, all were among unvaccinated people, highlighting concerns about declining vaccination rates since the COVID-19 pandemic, which have fallen below the 95% herd immunity threshold. Public health officials emphasize that vaccine hesitancy is a key factor in the resurgence, and the CDC continues to provide support and urges vaccinations to control the outbreak. The situation underscores the urgent need to address vaccination coverage to prevent further spread of this highly contagious and potentially severe disease.
