With the CDC only updating their measles case counts monthly, and since their last update on February 7, 2025 there have already been dozens of new cases across the country, tracking measles cases in the U.S. will require scanning state and local health department alerts.

The Texas Department of State Health Services is reporting an outbreak of measles in the South Plains region of Texas. Due to the highly contagious nature of this disease, additional cases are likely to occur in Gaines County and the surrounding communities. DSHS is working with South Plains Public Health District and Lubbock Public Health to investigate the outbreak.
And even more concerning, is that the latest measles case count likely represents only a fraction of the true number of infections. Health officials suspect 200 to 300 people in West Texas are infected but untested, and therefore not part of the state’s official tally so far.
The outbreak is in a sparsely populated swath of rural Texas, near the New Mexico border, and has spread from its epicenter in Gaines County to include single-digit cases in Lynn, Terry and Yoakum counties. The cases have been concentrated in a “close-knit, undervaccinated” Mennonite community, Texas Department of State Health Services spokesperson Lara Anton said. Gaines County is highly rural, so many of the families send their children to small private schools or are homeschooled, Anton said.
Measles cases were limited to rural areas surrounding Lubbock, Texas, the largest city in the region, until February 14th, when Lubbock Public Health confirmed its first case. People who live in Gaines County regularly head into Lubbock to shop and do other business. That includes a large number of unvaccinated people who may have been exposed to measles.
“Communities who don’t vaccinate are not necessarily isolated to their area. They commute to Lubbock,” said Dr. Ana Montanez, a pediatrician at Texas Tech Physicians in Lubbock. “By doing that, they’re taking the disease with them.”
Several of Montanez’s young patients were exposed recently, she said, one just by sitting in the same clinic waiting room with another child who was later confirmed to have measles. That child had traveled from another county for care.
One case was also reported in neighboring Lea County on February 11th, where residents were alerted Tuesday to a measles case in an unvaccinated teenager. The New Mexico Department of Health said the teen had no recent travel or exposure to known cases from the Texas outbreak. Two additional cases identified in Lea County on February 14th, unrelated to the first case. By February 20th, the number of cases rose to 9.
