Well, this is one of the major problems I have with the standard theory. I've never heard of an actual case of somebody getting AIDS from a needle-stick accident. Not a doctor, not a nurse, not an EMT, or policeman, or firefighter. I live in a large city with supposedly one of the largest numbers of AIDS cases in the developed world. I have never heard of a person who wasn't leading either a fast-lane gay lifestyle including "recreational" drugs or living as a heroin or cocaine addict getting AIDS. There were hundreds of HIV-positive prostitutes identified in studies done in this city in the 1990s (all of them drug users) but I have never heard of a case of a customer developing AIDS as a result. So what's going on here? I don't know, but it doesn't look like a contagious disease to me.
