(LUBBOCK, Texas) — An unvaccinated school-aged child in Texas has died of measles, the first associated with an outbreak in the western part of the state that has infected more than 100 people.
Lubbock city spokesperson Lauren Adams confirmed the death to ABC News on Wednesday.
In a press release, the Texas Department of State Health Services (DSHS) said the child was hospitalized in the northwestern city of Lubbock last week and tested positive for measles.
As of Wednesday, 124 cases of measles have been confirmed associated with the outbreak, according to data from DSHS.
Almost all of the cases are in unvaccinated individuals or individuals whose vaccination status is unknown, and 18 people have been hospitalized so far, DSHS said.
Children and teenagers between ages 5 and 17 make up the majority of cases with 62, followed by 39 cases among children ages 4 and under.
The outbreak began in Gaines County, which has become the epicenter, with 80 cases confirmed among residents, according to DSHS.
The outbreak has since spread to several counties in the region and is “suspected” to have spread into New Mexico, according to New Mexico Department of Health (NMDOH). Nine cases have been confirmed in Lea County, which borders Texas. Of the nine cases, four are among children, according to NMDOH.
“This death underscores the real danger of measles — it’s a severe disease that can take lives despite being preventable with vaccination,” said Dr. John Brownstein, an epidemiologist and ABC News contributor. “Every new case is a reminder of why vaccination is critical. Tragically, with an outbreak of this scale, a fatal case was not unexpected, especially among those unvaccinated. Given how contagious measles is, we anticipate more cases in the coming weeks.”
Measles is one of the most contagious diseases known to humans. Just one infected patient can spread measles up to nine out of 10 susceptible close contacts, according to the Centers for Disease Control and Prevention (CDC).
Health officials have been urging anyone who isn’t vaccinated to receive the measles, mumps, rubella (MMR) vaccine.
The CDC currently recommends people receive two vaccine doses, the first at ages 12 to 15 months and the second between 4 and 6 years old. One dose is 93% effective, and two doses are 97% effective. Most vaccinated adults don’t need a booster.
Measles was declared eliminated from the U.S. in 2000, due to the highly effective vaccination program, according to the CDC. However, vaccination rates have been lagging in recent years.
About 93% of kindergarteners nationwide received select routine childhood vaccines, including the MMR vaccine, for the 2022-23 school year, according to a November 2023 CDC report.
This is about the same as the previous school year, but lower than the 94% seen in the 2020-22021 school year and the 95% seen in the 2019-2020 school year, prior to the COVID-19 pandemic. The latter percentage had been the standard for about 10 years.
