The child was found wrapped in wet blankets, covered with branches, and suffering from hypothermia.
The woman that found the child is a "recicladora" (someone who sorts through garbage to find things to sell, such as metal). The woman saw the tiny bundle under the branches and went to see if it was something useful.
When she realized that it was a baby, she called two other people over to witness that the child was covered in ants and turning blue. Quickly, the woman -- Concepcion Arenas -- cleaned up the baby and got on a motorcycle with someone who could take the child to the hospital.
The baby is recuprating in an incubator at a local hospital in Santa Fe de Antioquia, where the hospital staff named her Manuela.
