A measles outbreak that began in Texas has spread to several other states, marking the largest outbreak in the U.S. since the disease was declared eliminated in 2000.
As of May 6, 2025, the Texas Department of State Health Services has confirmed 702 cases, primarily in West Texas counties including Cochran, Dallam, Dawson, Gaines, Garza, Lynn, Lamar, Lubbock, Terry, and Yoakum.
The outbreak has resulted in 91 hospitalizations and two deaths, both of which involved unvaccinated school-aged children.
Less than 5% of those infected in Texas had received the measles-mumps-rubella (MMR) vaccine. The outbreak has spread rapidly among communities with low vaccination rates, particularly within the Mennonite community in Gaines County.
The Centers for Disease Control and Prevention (CDC) reports that the total number of measles cases across the U.S. has surpassed 1,000 this year, with Texas being a major contributor. Health officials emphasize the importance of vaccination to prevent further spread.
Measles symptoms typically appear 10 to 14 days after exposure and include high fever, cough, runny nose, inflamed eyes, and a red rash.
Severe complications, including pneumonia, brain swelling, and death, can result from the disease. Health officials are continuing efforts to raise awareness about vaccination and reduce further transmission.
