Overview

• The outbreak sickened 762 people since January, led to 99 hospitalizations and two deaths, with the last Texas case reported on July 1.
• Most infections were in people who were unvaccinated or had unknown status, and more than two-thirds of cases occurred in children.
• Gaines County, a low-coverage area tied to a rural Mennonite community, accounted for 414 cases and seeded linked cases in New Mexico, Oklahoma, Kansas, Mexico and Canada.
• Meeting the two-incubation-period benchmark, the state will continue surveillance but is discontinuing its public outbreak dashboard and urges clinicians to test suspected cases.
• Nationally, the CDC has counted 1,356 measles cases in 2025 — the most since 1992 — as declining MMR coverage and rising exemptions leave communities susceptible.
