London, May 22 : Kerstin, one of the children Austrian incest fiend Josef Fritzl fathered with his daughter Elisabeth, is showing signs of a miraculous recovery as she fights for her life in coma.
Medics are so amazed by Kerstin's fightback that they are considering trying to wake her.
When Fritzl rushed her to hospital last month, medics feared the 19-year-old would die from kidney failure.
Doctors said the dungeon existence had triggered serious infections and Kerstin was put into an artificial coma at the hospital in Amstetten, Austria.
At one point, ghostly-white Kerstin was given just hours to live after her vital organs began to shut down.
Now specialists say she is showing signs of recovery, although severe cramps could have left her with a shortage of oxygen - and therefore brain damage.
"Kerstin's condition has greatly improved in recent days. The medication keeping her in an artificial coma is being slowly reduced," The Daily Star quoted Dr Albert Reiter, as saying.
"This is the first phase in the process of eventually waking her up. How long this will take is something we cannot say," he added.
