WASHINGTON, Feb 2 (Reuters) - U.S. immigration officials have quarantined some migrants and halted "all movement" after two measles cases were confirmed among detainees at its facility in south Texas, the Department of Homeland Security said on Monday.

The cases at Dilley Immigration Processing Center were confirmed by the state's health department on Saturday, DHS said in a statement, adding that "all detainees are being provided with proper medical care."

"ICE Health Services Corps immediately took steps to quarantine and control further spread and infection, ceasing all movement within the facility and quarantining all individuals suspected of making contact with the infected," the department added.

"Medical staff is continuing to monitor the detainees’ conditions and will take appropriate and active steps to prevent further infection."

The two Texas cases come amid rising measles cases across the country, including elsewhere in the state and in South Carolina, which has seen the biggest state-level outbreak so far with 789 infections.

Texas led a surge in measles cases nationally in 2025 with 762 infections mostly in the west, with the United States recording its largest outbreak since the disease was declared eliminated from the country in 2000. The state's outbreak was declared over in August.

ICE's Dilley facility, operated by the private company CoreCivic CXW.N, was opened in 2014 to house migrant families caught crossing the U.S.-Mexico border illegally. It had been due to close under the Biden administration but was since recontracted under ICE last year under U.S. President Donald Trump as part of his immigration crackdown.
