Cure for HIV claimed, but not yet proven

A man with HIV living in Germany may have been cured of his infection by a bone marrow transplant, researchers claim.

In 2007, the man received a bone marrow transplant to treat his leukemia. The transplant — which treats leukemia by essentially rebooting the body’s immune system and creating new white blood cells —also had the benefit of wiping out the HIV infection. Now, three and a half years later, the patient remains HIV-free, which suggests he is cured of the disease, the researchers said.
