A US woman is suing a hospital for assault after a doctor circumcised her baby son by mistake.Vera Delgado's son, Mario Viera, was circumcised without her consent at South Miami Hospital when he was eight days old."Oh, my God," Delgado asked the Miami Herald. "How could this happen?""I didn't want this for him. I'm opposed to circumcision. They didn't have the right to do it."Mario was kept in intensive care after he was born to fight an infection. Arriving to visit him one day, his mother noticed a vial by his bed. A nurse told her it was a painkiller given for his circumcision.The hospital says it is "deeply sorry" and vowed to take steps to prevent the mistake from happening again."The baby's circumcision was an unfortunate mistake caused by a misread consent form. As soon as the error was discovered, the doctor and nurses let the family know what had occurred," said a spokesman.But Ms Delgado says that's not enough. She has filed a lawsuit against the hospital and reported the doctor to police for assault."It's a big deal," she said. "In the future, he's going to ask why his dad is one way and he's different."Source: orange news
