New research gives hope of finding HIV cure

Scientists in the United States say there is growing evidence they may have stumbled across a treatment, if not a cure, for AIDS.

There has been one case of this happening before.

But now they have revealed that two more HIV positive men, who had bone marrow transplants as part of cancer treatment, have no detectable levels of the virus in their blood.
