Measles Outbreak in Southwest US Exceeds 250 Cases with Two Deaths
A growing measles outbreak across Texas, New Mexico, and Oklahoma has surpassed 250 cases and resulted in two deaths, prompting health officials to urge vaccination.
- Over 250 measles cases have been reported in Texas, New Mexico, and Oklahoma.
- Two deaths have occurred: a child in Texas and an adult in New Mexico.
- Texas has recorded 223 cases with 29 hospitalizations.
- The CDC defines an outbreak as three or more related cases; three clusters occurred in 2025.
- MMR vaccination is the primary prevention method, with two doses recommended for children.
Measles infections in West Texas and New Mexico have surged to more than 250 cases, with two unvaccinated individuals dying from measles-related complications. The outbreak highlights a significant resurgence of the highly contagious airborne virus, which had been considered eliminated in the United States since 2000.
Texas health officials reported 223 total cases as of Tuesday, including 29 hospitalizations and 25 new infections recorded in the past week. New Mexico has confirmed 33 cases, with the spread extending from Lea County into neighboring Eddy County. Oklahoma’s state health department also identified two probable cases linked to the southwestern cluster.
The human toll includes a school-age child who died in Texas last month and an adult who died in New Mexico last week, marking the state’s first measles-related death. While the epicenter remains in the Southwest, isolated cases have been reported in Alaska, California, Georgia, Kentucky, Maryland, New Jersey, New York, Pennsylvania, and Rhode Island.
The Centers for Disease Control and Prevention (CDC) defines an outbreak as three or more related cases. Three such clusters have qualified as outbreaks in 2025. Most U.S. cases originate from individuals who contracted the disease abroad, spreading rapidly within communities with low vaccination rates.
Health experts emphasize that the measles, mumps, and rubella (MMR) vaccine is the most effective prevention method. The CDC recommends two doses: one between 12 and 15 months of age, and a second between 4 and 6 years old.
Adults with documented immunity generally do not need revaccination. This includes those born before 1957, who are presumed immune due to likely natural infection, or those with lab-confirmed past infection or adequate vaccination records. However, individuals who received an ineffective killed-virus vaccine before 1968 should be revaccinated.
Scott Weaver of the Global Virus Network noted that high-risk individuals, such as those living with infected persons or suffering from respiratory conditions, may consider boosters if they reside in outbreak areas. The CDC states that receiving an additional MMR shot is harmless for those concerned about waning immunity.
There is no specific treatment for measles; medical care focuses on alleviating symptoms and preventing complications.
