On February 1, 2026, the Department of Homeland Security (DHS) confirmed two measles infections among detainees at the Dilley Immigration Processing Center in Texas. This facility is notable for housing 5-year-old Liam Conejo Ramos and his father, Adrian Alexander Conejo Arias, who were recently released.
Following the diagnoses, DHS spokesperson Tricia McLaughlin announced a complete lockdown of the facility, ceasing all movement and quarantining individuals believed to have had contact with the infected detainees. "All detainees are being provided with proper medical care," McLaughlin stated, emphasizing the health services available at the center.
Medical professionals are actively monitoring conditions inside the facility, ensuring that appropriate steps are taken to prevent any further infections. Measles, known for its highly contagious nature, spreads through airborne transmission and remains viable on surfaces for several hours. Symptoms can include high fever, red eyes, cough, and a characteristic rash, with serious complications possible, especially in vulnerable populations such as infants and those with compromised immune systems.
Liam and his father were detained while returning home from his preschool in Minnesota on January 20, sparking public outcry. They were held until a federal judge ordered their release on January 31. Although it remains unclear whether Liam and his father had contact with the infected individuals, their detention raised significant concerns regarding the treatment of families in immigration custody.
Recent reports indicate a notable resurgence of measles cases in the U.S., with over 2,200 infections documented in 2025, marking the highest levels seen in decades. Experts attribute this rise to declining vaccination rates, which undermine efforts to maintain herd immunity against the disease.
As the Dilley facility navigates this public health challenge, lawmakers and attorneys have expressed alarm and the need for inspections to ensure the safety and health of all detainees. The situation continues to develop, highlighting the intersection of immigration policy and public health in the face of resurgent infectious diseases.
