1. 2009 Estimates for the
HIV/AIDS epidemic
in China

2. Aims and estimation methods
To provide update on estimates of populations affected by HIV to guide policy and programming.
Methods
Workbook was used for development of the estimates.
Estimation and Projection Package (EPP) and Spectrum were used to estimate the number of new infections and deaths after consideration of the impact of antiretroviral treatment.

People living with HIV 740,000
Number of AIDS 105,000
New HIV infections 48,000
Deaths due to AIDS 26,000

6. Geographical distribution of estimated 740,000 PLHIV in 2009

7. Mode of transmission– total PLHIV in 2009
Total number of PLHIV: 740,000

8. Mode of transmission – new HIV infections in 2009
Total number of new infections: 48,000

9. Epidemic features in China
The rate of increase in the growth of the epidemic has slowed further.
Sexual transmission continues to be the primary mode of HIV transmission, with homosexual transmission increasing rapidly.
National prevalence is low, but the epidemic is serious in some areas and among some most-at-risk populations.
The number of people affected by HIV/AIDS is increasing and modes of transmission are diversifying.
