On January 30, 2025, the South Plains Health Department announced that there were two confirmed cases of measles in Gaines County. Both cases were unvaccinated school-aged children who had been hospitalized in Lubbock and since discharged. On February 5th, the Texas Department of State Health Services (TDSHS) declared a measles outbreak in Gaines County, with a total of 6 cases in unvaccinated school-aged children. A week later, on February 11th, cases quadrupled from 6 to 24, including two adults. Nine of the cases had been hospitalized. Three days later, on February 14th, cases in Texas doubled yet again from 24 to 48, and the outbreak expanded to 3 other counties in the South Plains region. The cases were predominantly in the Mennonite community, which has low vaccination rates.
By mid-March the outbreak had spread across West Texas, including over a dozen counties, from the South Plains region to the Panhandle region, and also appeared in East Texas. By early April the outbreak encompassed nearly two-dozen counties and also began appearing in North Texas. By late May, outbreak-related cases were identified in 35 counties, primarily in West Texas and the Panhandle region, but also scattered through North and Central Texas, including urban areas of Dallas-Forth Worth and Waco.
Meanwhile, on February 11th the New Mexico Department of Health (NMDOH) reported a confirmed case of measles in Lea County. The unvaccinated teenager with no recent travel or exposure to known cases from the Texas outbreak. On February 14th, the NMDOH reported that two adult residents of Lea County tested positive for measles, thus declaring a measles outbreak, based on the CDC's criteria of three unrelated cases in Lea County. While initially the cases in New Mexico were not believed to be linked to the cases in Texas, by mid-March it was confirmed that the cases were linked to the West Texas outbreak.
While the majority of cases in New Mexico are in Lea County, directly across the border from Gaines County, Texas, and its surrounding counties, by late-May, cases has spread to 7 counties throughout the state.
On March 11th the Oklahoma State Department of Health (OSDH) reports two confirmed cases of measles who had known exposure to cases in West Texas, with two additional probable cases identified on March 14th.
While the OSHD has not been reporting counties with confirmed cases, many local health departments have announced cases within their county, with the majority of cases in the northeastern part of the state, around Tulsa.
On March 13th, the Kansas Department of Health and Environment (KDHE) announced a confirmed measles case in Stevens County. It was not known whether the case was associated with any ongoing outbreak. On March 26th, the KDHE announced that they were investigating a possible link to the broader outbreak whose epicenter is in Gaines County, Texas, approximately 375 miles away. “The confirmed cases in Kansas have a possible link to the outbreaks in Texas and New Mexico,” said Jill Bronaugh, communications director for the KDHE. “While genetic sequencing of the first Kansas case reported is consistent with an epidemiological link to the Texas and New Mexico outbreaks, the source of exposure is still unknown.”
The early Kansas cases were located in Stevens and Morton counties in the southwest corner of the state, however, by May cases started exploding in neighboring counties, including Haskwell and Gray. In late-May an outbreak in Pawnee County was confirmed to be linked to the broader outbreak.
The outbreak began in a sparsely populated swath of rural Texas, in Gaines County, near the New Mexico border. The initial cases were 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.”
After first appearing in the rural South Plains region of Texas, the outbreak spread across the border into Lea County, New Mexico; that has now spread to neighboring counties in New Mexico and has even jumped hundreds of miles into the Texas Panhandle and Northeast Texas. Cases then appeared in the northeastern part of Oklahoma in mid-March and on March 26th, the Kansas Department of Health and Environment announced a possible link between the state's growing outbreak and the ongoing outbreak in Texas.
On February 11, 2025 the Texas State Department of Health Services (TSDHS) launched a Measles Outbreak 2025 dashboard with updated information on case counts by county and date of rash onset, as well as age and vaccination status of cases. They also provide updates on the number of cases requiring hospitalization and the number of measles deaths.
The dashboard is updated twice-weekly on Tuesdays and Fridays.
The New Mexico Department of Health (NMDH) launched the 2025 Measles Outbreak Guidance dashboard on February 28th, 2025 with information and guidence, including case counts, hospitalizations, and deaths by county, cases by date of rash onset (or, if unavailable, date of symptom onset, specimen collection, hospital admission, or reported), as well as age and vaccination status of cases.
The dashboard is updated twice-weekly on Tuesdays and Fridays.
The Oklahoma State Department of Health (OSDH) launched the Oklahoma Measles Situation Update dashboard on March 20, 2025, with information on case counts, vaccination status of cases, hospitalizations and deaths, as well as public setting exposure notifications.
The dashboard is updated twice-weekly on Tuesdays and Fridays.
The Kansas Department of Health and Environment (KDHE) launched a 2025 Kansas Measles Outbreak Dashboard on March 28, 2025, with information on case counts by county and week of symptom onset, age and vaccination status of cases, as well as hospitalizations and deaths.
The dashboard is updated twice-weekly on Mondays and Wednesdays.
