The parents of a newborn who died in a Pennsylvania hospital’s neonatal intensive care unit allege in a lawsuit that hospital officials failed to protect their son from a lethal bacterial infection that had already killed two other babies.

Geisinger Medical Center knew the neonatal intensive care unit of its flagship hospital in Danville was “dangerous, defective and contaminated” but continued filling its beds with premature infants and hid the obvious danger from parents, according to a wrongful-death suit filed Thursday.

Abel Cepeda was 5 days old when he died at the hospital Sept. 30. He was the third premature infant in two months to die from an infection caused by the Pseudomonas bacterium, and the eighth to be infected.
