 The reported incidence of HIV/AIDS in China is relatively low, but the Chinese government anticipates that the number of individuals infected annually will continue to increase.While HIV is a type of sexually transmitted infection, the first years of the epidemic in China were dominated by non-sexual transmission routes, particularly among users of intravenous drugs through practices such as needle sharing.By 2005, 50% of new HIV cases were due to sexual transmission, with heterosexual sex gradually becoming the most common means of new infections in the 2000s.
