Amalia Arrieta, an 18-month-old from Venezuela, was detained with her mother Kheilin Valero Marcano following an ICE appointment in El Paso on December 11, 2025, and transferred to Dilley Immigration Processing Center. Over weeks, Amalia developed severe respiratory symptoms including high fevers, persistent cough, and dangerously low blood-oxygen levels (dropping to the 50s). On January 18, 2026, she was hospitalized at Methodist Children's Hospital in San Antonio for 10 days, diagnosed with pneumonia, COVID-19, RSV, and respiratory distress. Upon discharge on January 28, doctors prescribed her a nebulizer, respiratory medications, and nutritional supplements. When ICE returned her to Dilley, detention staff allegedly confiscated her prescribed medications and breathing equipment. Her parents were forced to wait in daily outdoor lines to request treatment, often being denied. After lawyers filed an emergency habeas corpus petition in federal court, the family was released on either January 31 or February 7, 2026.
