A significant measles outbreak in West Texas has grown to 58 cases, with an additional eight cases now reported in neighboring eastern New Mexico. The outbreak marks the region's most severe measles crisis in nearly three decades.

Of the confirmed Texas cases, thirteen patients have required hospitalization. While four of the infected individuals were vaccinated, the remainder were either unvaccinated or had unknown vaccination status.

The outbreak is primarily concentrated in Gaines County, Texas, where 45 of the 58 cases have been identified. The county, with approximately 22,000 residents, has one of the state's highest vaccine exemption rates, with nearly 14 percent of K-12 students having vaccine exemptions during the previous school year.

Health officials have traced many cases to a 'close-knit, undervaccinated' Mennonite community, particularly among families whose children attend private religious schools or are homeschooled.

In New Mexico, at least three cases have been reported in Lea County, which borders Texas' Gaines County. Health officials have identified potential exposure sites including a grocery store, an elementary school, a church, Nor-Lea Hospital, and a Walgreens in Hobbs, New Mexico.

The measles virus is highly contagious, capable of surviving in the air for up to two hours, with up to 9 out of 10 susceptible individuals contracting the virus upon exposure. Symptoms include high fever, cough, runny nose, and a characteristic rash that begins on the face before spreading to the rest of the body.

Public health officials emphasize that the measles, mumps and rubella (MMR) vaccine remains the most effective prevention method. Health workers are responding to the outbreak by hosting regular vaccination clinics and screening efforts, while working with schools to educate communities about vaccination importance.
