Texas measles cases rises to 146 in an outbreak that led to a child's death

DALLAS (AP) — The number of people with measles in Texas increased to 146 in an outbreak that led this week to the death of an unvaccinated school-aged child, health officials said Friday.

The number of cases — Texas’ largest in nearly 30 years — increased by 22 since Tuesday. The Texas Department of State Health Services said cases span over nine counties in West Texas, including almost 100 in Gaines County, and 20 patients have been hospitalized so far.

The child who died Tuesday night in the outbreak is the first U.S. death from the highly contagious but preventable respiratory disease since 2015, the U.S. Centers for Disease Control and Prevention said. The child was treated at Covenant Children’s Hospital in Lubbock, though the facility said the patient didn’t live in Lubbock County.

The virus has largely spread through rural, oil rig-dotted West Texas, with cases concentrated in a “close-knit, undervaccinated” Mennonite community, state health department spokesperson Lara Anton has said.

Gaines County has a strong homeschooling and private school community. It is also home to one of the highest rates of school-aged children in Texas who have opted out of at least one required vaccine, with nearly 14% skipping a required dose last school year.

The measles, mumps and rubella (MMR) vaccine is safe and highly effective at preventing infection and severe cases. The first shot is recommended for children ages 12 to 15 months, and the second for ages 4 to 6 years. Most kids will recover from measles, but infection can lead to dangerous complications such as pneumonia, blindness, brain swelling and death.

Vaccination rates have declined nationwide since the COVID-19 pandemic, and most states are below the 95% vaccination threshold for kindergartners — the level needed to protect communities against measles outbreaks.

The U.S. had considered measles, a respiratory virus that can survive in the air for up to two hours, eliminated in 2000, which meant there had been a halt in continuous spread of the disease for at least a year. Measles cases rose in 2024, including a Chicago outbreak that sickened more than 60.

Eastern New Mexico has nine cases of measles currently, but the state health department said there is no connection to the outbreak in West Texas.
