I can tell you one thing though, aids is slowly but surely taking over the world.
I think Aids is something that needs to dealt with soon or it's going to explode. The only way to cure aids is to basically round up everyone who has it and well ......, that would mean whiping out Half of africa's population though, would not sit well i would imagine.
another good reason to pursue stem-cell research..
Another manner would be simply replacing the organs arround the effected area, say from a host.
And in this situation, the host may be an headless clone.
Of course, this is ethical, seeing that the clone would not bare any consciousness.
