A significant measles outbreak in West Texas has grown to 124 confirmed cases across nine counties, with 18 people currently hospitalized, according to the Texas Department of State Health Services [1]. The outbreak, described as the state's largest in nearly 30 years, is primarily affecting an undervaccinated Mennonite community.

The outbreak has seen a sharp increase of 34 new cases since Friday, with Gaines County reporting the highest concentration at 80 infections. Terry County follows with 21 cases, while other affected counties report single-digit numbers [1].

Demographics data reveals that the majority of cases are among youth, with 39 infections in children under 4 years old and 62 cases in those aged 5-17. Eighteen adults have contracted the virus, with five cases pending age determination [1].

In neighboring New Mexico, nine cases have been reported in Lea County, though health officials state there is currently no evidence linking these cases to the Texas outbreak [2].

'I've never seen it this close, ever,' said Brownfield Mayor Eric Horton. 'I know that we've had a few outbreaks in years past but as far as right here, making national news, that is shocking.' [1]

The CDC reports that measles is highly contagious, with up to 90% of unvaccinated people becoming infected upon exposure [3]. The virus can survive in the air for up to two hours and can lead to serious complications including pneumonia, blindness, and brain swelling.

Public health officials are responding with vaccination clinics and educational outreach. The CDC is providing technical assistance and laboratory support to Texas health authorities, who are leading the outbreak investigation [1].

Gaines County, at the center of the outbreak, reports one of Texas's highest vaccine exemption rates, with nearly 14% of K-12 students opting out of at least one required vaccine during the 2023-24 school year [1].
