Yes, spread among most homosexuals and drug uses, but how would you account for heterosexual women catching it as well?
I view AIDS, which is real, as a deficiency of the immune system. That can happen to anyone. It becomes "AIDS" when you test positive for an antibody of HIV not a test for HIV. That mostly happens to gays and drug users whose lifestyle promote weakened immune systems and the trading of lots of infections. But occasionally it will happen to people like you and me. But in any case you do not see a spread of this supposed HIV virus and AIDS into the general population. That virus is not the cause of AIDS.
Google Duesberg and read what he has to say on the subject. You will easily be convinced that the whole HIV = AIDS story is just another very successful Global Warming type scam.
