The 2007 estimates for the number of people exposed to and infected with HIV in China utilized data newly available through expanded screening and surveillance, while also building on the experience gained during the 2003 and 2005 estimation work. As with past estimates, the workbook method recommended by the World Health Organization (WHO) and United Nations Program on HIV/AIDS (UNAIDS) was chosen as the most suitable for an epidemic still concentrated among certain subpopulations and in a situation where data are still relatively limited.
Populations at higher risk for HIV infection including female sex workers (FSWs), injecting drug users (IDUs), and men who have sex with men (MSM) still make up a large portion of new infections in 2007. However, there are signs that HIV is increasingly becoming a generalized epidemic as sexual contact replaces injecting drug use as the most common mode of transmission.
