An article analysed that with an imbalanced sex ratio of 1.2:1, the excess of men and a skyrocketing number of prostitutes (the author meaned female prostitutes) will create a favorable enviroment for the spread of AIDS in China.

I didn’t find the link to the original article but you can read a Nature news: Surfeit of boys couls spread AIDS in China’s cities.
