Doctors in Mississippi and Boston say a baby born with the virus that causes AIDS has been cured after an agressive treatment of drugs.

The child and her HIV-infected mother were treated at Jackson Medical Center in Mississippi.

Doctors prescribed three different medications to the baby right after she was born to fight the disease. But they lost track of the mother and child for a whole year.

When they finally found them, they discovered the mother had stopped giving her child the medications. They also found that the girl, who is now two and a half, remained healthy without the meds.

The early intervention appears to have knocked the virus out of the baby's blood.

"We have, perhaps inadvertently, but in fact, cured the child," Dr. Hannah Gay, with the University of Mississippi Medical Center, said.

After the baby's labwork was checked and double checked, doctors from Boston and Baltimore were brought in to begin research.

Now doctors are working to replicate the drug regimen, hoping their findings will help other HIV-infected babies.

They say if the child remains healthy, it would mark the world's second reported medical cure of HIV.
