HIV Cured???

News out today about an American in Germany who had a bone marrow transplant for Leukemia. Appearantly he was HIV+ before the procedure and the Doctors specifically looked for a donor who had the CCR5 delta 32 mutation which 1% to 3% of the population has. This mutation seems to be resistant to most forms of HIV. Well 2 years since the procedure and this guy has no sign of HIV. Could this be the elusive cure the world has been looking for? The Doctors said this is a start but is not a possible cure since a bone marrow transplant is very difficult and dangerous and not an option for everyone.
