(CBS/AP) Doctors say 24-year-old graduate student Aimee Copeland, who is battling a flesh-decaying bacteria she contracted from a zip line accident, remains in critical condition.

Aimee Copeland "very responsive," but to lose hands and other foot to necrotizing fasciitis, says report

Officials said Friday that 24-year-old Aimee Copeland was listed in critical condition at the Joseph M. Still Burn Center at Doctors Hospital in Augusta, Ga.

Aimee's father Andy also gave an update on his daughter's condition Friday morning in a blog on the University of West Georgia Psychology department student website:

"Aimee is alert and trying to mouth questions. Her breathing tube has been reoriented to increase her comfort and allow them to try to read her lips," Andy wrote. "She said: 'I can't talk!' We told her it was because of the tube, and we explained the need for it. 'Take it out!' She also asked 'what happened?' and 'where am I?'"

"I thought it would be better when she became alert, but it is actually harder for us," he wrote.

Copeland suffered a cut on her leg after falling from a homemade zip line May 1 as she and her friends kayaked along the Little Tallapoosa River in Carrollton, Ga.

The University of West Georgia graduate psychology student was diagnosed with necrotizing fasciitis, an infection that destroys human tissue. She had most of her right leg amputated last week because of the infection.

Family members said Thursday she will lose her hands and remaining foot to the infection. But her father also said Thursday that his daughter is improving, and that she has been coherent and alert. A blog post on Thursday said her neurologist said there was no indication of brain damage, and the cardiopulmonologist says Copeland's lungs are improving.
