Austin, May 1, 2025 – A major measles outbreak centered in West Texas is raising alarm among public health experts, as it threatens to undermine the United States’ 25-year record of having eliminated the disease. The outbreak, which began in late January, has already resulted in more than 700 reported cases, dozens of hospitalizations, and the first U.S. measles-related deaths in over a decade.
Outbreak Spreads Across States
Texas remains the epicenter, with 663 confirmed cases as of Tuesday, according to the Texas Department of State Health Services. Gaines County in West Texas is the hardest-hit area, accounting for nearly 400 cases. The outbreak has also spread to multiple states, with active clusters now reported in Indiana, Kansas, Michigan, Montana, Ohio, Pennsylvania, and Tennessee. Nationally, the Centers for Disease Control and Prevention (CDC) reports 884 confirmed measles cases so far in 2025-nearly triple the total recorded in 2024.
First Measles Deaths in a Decade
Tragically, the outbreak has claimed the lives of at least two school-aged children in Texas and one adult in New Mexico-the first measles-related deaths in the U.S. since 2015. Of the Texas cases, 87 have required hospitalization. The majority of those affected have been unvaccinated or have unknown vaccination status, highlighting the vulnerability of communities with low immunization rates.
Declining Vaccination Rates Fuel Resurgence
Health experts attribute the rapid spread to declining childhood vaccination rates, a trend worsened since the COVID-19 pandemic. Increasing numbers of parents are seeking exemptions on religious or personal grounds, leading to erosion of the critical “herd immunity” needed to prevent outbreaks. Communities with vaccination rates above 95% are generally protected, but those falling below remain at risk.
U.S. Elimination Status at Risk
The United States declared measles eliminated in 2000, following a robust national vaccination campaign that interrupted endemic transmission for more than a year. According to World Health Organization guidelines, a country maintains elimination status only if there is no continuous endemic transmission for at least 12 months, supported by strong disease surveillance. Epidemiologists now warn that if the Texas outbreak continues past the one-year mark, the U.S. could lose its elimination designation-a major setback for public health.
Public Health Response
Texas health authorities have launched public education campaigns, expanded testing, and set up vaccination clinics in affected areas, incurring millions in response costs. The CDC and local health departments continue to urge vaccination, emphasizing that two doses of the measles, mumps, and rubella (MMR) vaccine provide safe and effective protection against the disease37.
Looking Ahead
With the outbreak still ongoing and vaccination rates lagging in several communities, health officials remain vigilant. The situation is being closely monitored by global health authorities as a potential tipping point in the fight against vaccine-preventable diseases in the United States.
