The main cause of AIDS in China has NOT been sexual transmission but contaminated needles, mainly those shared by injection drug users, but also needles used in unsanitary ways during paid plasma collection. In poorer parts of China, selling blood is a common way to earn extra money, especially for drug users and commercial sex workers. Tragically, many of the blood-collecting companies are unlicensed and illegal, and their use of contaminated needles has been a major factor in spreading the disease.

The main cause of AIDS in China has NOT been sexual transmission...

Is not yet sexual transmission. The source(s) of AIDS in China are now well known. The question that begs to be asked now is: How will the virus continue to spread in the future?

IMO, if the heterosexual community starts to see infections, the amount of time for it's spread will not be long because of social behaviors.

especially for drug users and commercial sex workers.

Just out of curiosity, why do you call prostitutes "commercial sex workers"? And in your lexicon are there "non-commerical sex workers"? Just out of curiosity, since it's such a "values neutral" kind of pc-speech.
