AUGUSTA – Doctors say a young woman fighting a flesh-decaying bacteria she contracted after a zip line accident will lose her hands and remaining foot to the infection.

But Aimee Copeland’s father says the 24-year-old college student is improving.

Andy Copeland told The Atlanta Journal-Constitution on Thursday that his daughter is “coherent and alert.” Doctors treating her at an Augusta hospital say there is no indication of any brain damage and her lungs are slowly healing, but her hands and remaining foot will have to be amputated.

Copeland cut her leg after falling from a homemade zip line May 1.

The University of West Georgia graduate psychology student was diagnosed Friday with necrotizing faciitis, an infection that destroys human tissue. She lost most of her right leg to the infection.

Friends held a prayer vigil for Copeland on Thursday and planned a blood drive in her name Tuesday. They also established a fund for donations to help defray medical costs, and her father is updating Copeland’s progress on Facebook to raise awareness about the bacteria.
