Overview
- The Texas measles outbreak has surpassed the total U.S. case count for 2024, with 309 confirmed cases reported as of March 21, 2025.
- Children and teenagers aged 5-17 account for the majority of cases, followed by children aged 4 and under, highlighting the vulnerability of younger populations.
- Vaccination rates in Texas and New Mexico have increased but remain below the 95% threshold needed to prevent community spread, particularly in rural and religious communities.
- The outbreak has spread to 14 counties in Texas, two counties in New Mexico, and four probable cases in Oklahoma, complicating containment efforts in multistate regions.
- Public health officials warn the outbreak could last several more months or up to a year, potentially jeopardizing the U.S.'s measles elimination status if not contained.
