Estimating the Number of People at Risk for and Living with HIV in China in 2005: Methods and Results

No new estimates of HIV infection have been available for China since 2003. However, since then, data availability has increased dramatically. This document's objective is to use internationally recommended methods to make new estimates of the number of people exposed to HIV in China, the number living with HIV, and the number of new HIV infections and deaths in 2005.

The UNAIDS Workbook method was adapted to meet the needs of China. Local data were used to estimate the size of each risk population and HIV prevalence by risk group for every prefecture. These estimates were combined into provincial and national estimates. The UNAIDS Estimates and Projections Package and Spectrum were used to derive estimates of incidence and mortality from prevalence data, taking into account treatment.
