A measles outbreak in Texas and New Mexico has reached 99 confirmed cases, with public health officials warning that the number may rise. Texas health authorities reported 90 cases, while New Mexico confirmed nine, with most cases concentrated in Gaines County, Texas, where vaccination rates are among the lowest in the state.
Where Are the Cases?
In Texas, the outbreak has spread across seven counties, with Gaines County (57 cases) and Terry County (20 cases) being the hardest hit. Dawson County (6 cases), Yoakum County (4 cases), and single cases in Lubbock, Lynn, and Ector counties have also been reported.
In New Mexico, all nine cases are in Lea County, which shares a border with Gaines County, Texas. Health officials have identified possible exposure locations, including a grocery store, an elementary school, a church, Nor-Lea Hospital, and a Walgreens pharmacy in Hobbs, New Mexico.
Why Is the Outbreak Growing?
Health officials cite low vaccination rates as the primary factor in the outbreak’s rapid spread. In Gaines County, only 82% of kindergarteners were vaccinated last year, compared to the 95% threshold needed for herd immunity, as per CDC guidelines.
Texas allows “exemptions for reasons of conscience”, and Gaines County has one of the state’s highest vaccine exemption rates, with nearly 14% of K-12 students opting out. The outbreak has been particularly concentrated in an undervaccinated Mennonite community, according to the Texas Department of State Health Services.
How Contagious Is Measles?
Measles is one of the most contagious viruses known, spreading through coughing, sneezing, and direct contact. The virus can linger in the air for up to two hours, and 90% of unvaccinated individuals exposed will contract the disease.
Symptoms typically appear 7 to 14 days after exposure and include:
- High fever (can exceed 104°F)
- Cough, runny nose, and red eyes
- Koplik spots (tiny white spots inside the mouth)
- A red rash that spreads from the face to the rest of the body
Complications can be severe, with one in five unvaccinated individuals requiring hospitalization. Measles can also cause pneumonia, brain swelling (encephalitis), deafness, or even death.
What Are Officials Doing to Contain the Outbreak?
Health authorities in both states have launched vaccination drives and public awareness campaigns. In Gaines County and Lea County, free walk-in vaccination clinics have been set up. Schools and local health departments are offering free MMR shots and working to inform parents about the importance of vaccination.
The CDC has also issued a nationwide alert after cases in Texas drove a five-fold increase in weekly U.S. measles infections. There were only 14 cases nationwide last week, but that number has surged to 93 cases across multiple states, including California, Georgia, and New York City.
Who Is at Risk?
The CDC identifies the most vulnerable groups as:
- Children under 5 years old
- Adults over 20 years old
- Pregnant women
- People with weakened immune systems (e.g., leukemia, HIV patients)
Measles poses a particular threat to pregnant women, increasing the risk of premature birth and low birth weight.
How Effective Is the Measles Vaccine?
The MMR vaccine is safe and highly effective. Two doses provide 97% protection against measles, while a single dose is about 93% effective.
The vaccine is routinely given in childhood:
- First dose: 12–15 months old
- Second dose: 4–6 years old
If you are unsure of your vaccination status, check your records or consult your doctor. The CDC does not recommend boosters for those who received both doses in childhood, but certain high-risk adults—such as healthcare workers and international travelers—should confirm their immunity.
How to Protect Yourself
If you or someone you know has been exposed to measles, the CDC recommends:
- Getting vaccinated immediately if unprotected
- Avoiding contact with infected individuals
- Watching for symptoms for at least 21 days after exposure
- Wearing a mask and seeking medical care if symptoms develop
A National Concern
Measles was declared eliminated in the U.S. in 2000, but declining vaccination rates have fueled outbreaks in recent years. In 2024, the U.S. recorded 285 cases across 30 states, including a major outbreak in Chicago.
With vaccine skepticism growing, public health experts worry that future outbreaks could become more frequent and severe. The confirmation of Robert F. Kennedy Jr. as U.S. Health Secretary, despite his history of opposing vaccine mandates, has further raised concerns about the federal government’s commitment to immunization programs.
Conclusion
The Texas and New Mexico outbreaks highlight the dangers of declining vaccination rates. With nearly 100 cases and counting, health officials urge the public to get vaccinated and remain vigilant. Early intervention and increased immunization efforts are crucial to preventing measles from becoming a nationwide crisis once again.
