Federal and state health officials have confirmed multiple cases of measles at the South Texas Family Residential Center, an immigration detention facility located near Dilley in Frio County, raising renewed public health concerns about infectious disease control inside large scale detention environments.
According to the Department of Homeland Security (DHS) and the Texas Department of State Health Services, at least two individuals detained at the facility have tested positive for measles. The center, which can house up to 2,400 people, primarily holds families with children who are awaiting immigration proceedings.
The South Texas Family Residential Center is located approximately 70 miles south of San Antonio, along U.S. Highway 85, and reopened in 2025 after a period of closure. It is one of the largest family immigration detention facilities operating in the United States.
Containment Measures Implemented
Following confirmation of the cases, ICE Health Services Corps initiated immediate containment procedures. Facility officials restricted internal movement, isolated individuals believed to have been exposed, and began active medical monitoring in coordination with public health authorities.
Measles is considered one of the most contagious viral diseases and can spread rapidly in congregate living settings, particularly among individuals who are unvaccinated or whose vaccination history is unclear. Health officials have emphasized that early containment is critical to preventing further transmission within the facility.
Ongoing Health Concerns
The outbreak comes as immigration detention facilities continue to face scrutiny over healthcare access and disease prevention practices. Advocacy organizations and medical professionals have repeatedly warned that crowded detention conditions increase vulnerability to infectious disease outbreaks, especially among children.
In recent days, several lawmakers and public health advocates have renewed calls for stronger oversight of medical services within immigration detention centers. They argue that family detention facilities must maintain higher preparedness standards, given the health risks associated with housing large populations in close quarters.
Public Health Context
Texas has reported an increase in measles cases in recent years, mirroring a broader national resurgence of the disease. Public health officials stress that vaccination remains the most effective method of prevention and note that measles can be transmitted before symptoms appear, complicating containment efforts.
State and federal health agencies continue to monitor the situation at the Dilley facility. Officials have not indicated whether additional cases are under investigation but say preventive measures remain in place as a precaution.
