In this Tuesday, Nov. 5, 2019, photo, migrant Justina holds her daughter, Samantha, at a refugee camp where she lives in Matamoros, Mexico. Shortly after they entered the U.S. to seek asylum in September, Justina and Samantha were taken to a type of Border Patrol station that migrants refer to as the “hielera,” or icebox. Samantha started having a fever and a cough. Eventually, her illness developed into pneumonia. (AP Photo/Eric Gay)
