There are still holes in the story that HIV is the cause of AIDS. Is that because it is not the actual virus causing the illness, or is there yet another cause of AIDS besides a virus?

This is a complicated story that we cannot lay out in great detail, as that would require leading, but we can tell you, as a springboard from the ongoing controversy little reported in the popular press, science has been heavily misguided by the pioneers in the field, wanting to plant a flag and claiming victory, in pinning the blame for AIDS on this particular virus when it is one of a collection and not the true origin of the virulent form leading to death from immune deficiency. So it is a kind of red herring representing a solid clue, that one needs to look for a viral culprit, but science stopped too soon in the false assumption the answer is in hand when this has not yet been fully explored and pinned down with precision.
