Two measles cases at a Texas immigration center triggered a quarantine and halted all movement.

Two measles cases at the Dilley Immigration Processing Center in Texas have triggered a quarantine and halt to all movement within the facility, according to the Department of Homeland Security and Texas health officials. The outbreak, confirmed on January 31, prompted ICE Health Services Corps to isolate affected individuals and monitor others for symptoms. The facility, which houses detained families, has faced prior scrutiny over health conditions, including claims that a 5-year-old boy fell ill from food. The outbreak adds to a national rise in measles cases, with over 580 reported in the U.S. through early February 2026, driven by declining vaccination rates.
