WASHINGTON, Feb 2 - The Department of Homeland Security announced on Monday that U.S. immigration authorities have quarantined certain migrants and suspended "all movement" inside a south Texas detention center after two detainees were confirmed to have measles, the agency said in a statement.
The state health department identified the two cases at the Dilley Immigration Processing Center on Saturday, DHS said. In its statement the department added that "all detainees are being provided with proper medical care."
According to DHS, medical teams from the ICE Health Services Corps moved immediately to isolate infected individuals and to contain potential transmission by stopping internal movements within the facility and quarantining everyone suspected of having been in contact with those infected. The agency said: "Medical staff is continuing to monitor the detainees conditions and will take appropriate and active steps to prevent further infection."
The two confirmed infections at Dilley arrive as measles cases are increasing nationwide, the statement noted, with outbreaks reported elsewhere in Texas and in South Carolina. South Carolina currently accounts for the largest state-level outbreak mentioned in the notice, with 789 infections.
The DHS statement referenced earlier figures for Texas and the nation: Texas led a national surge in measles in 2025 with 762 infections, concentrated mostly in the western part of the state. That nationwide surge produced the largest U.S. outbreak since measles was declared eliminated from the country in 2000. The Texas outbreak was declared over in August, the department said.
Dilley is run by the private company CoreCivic. Opened in 2014 to house migrant families apprehended at the U.S.-Mexico border, the facility had been scheduled to close under the Biden administration but was recontracted by ICE last year under U.S. President Donald Trump as part of his administrations immigration crackdown, the statement noted.
Officials emphasized that medical personnel are actively monitoring conditions at the center and have implemented quarantine and movement restrictions to limit the risk of further spread within the facility. No additional case counts at Dilley were provided in the statement.
