AIM: To describe trends in the HIV epidemic among drug users (DUs) in China from 1995 to 2011.
DESIGN, SETTING AND PARTICIPANTS: Data sets from China's national HIV/AIDS case reporting and sentinel surveillance systems as of December 2011 were used separately for descriptive analysis.
MEASURES: Changes in the geographic distribution of the number of HIV cases and HIV prevalence among injecting drug users (IDUs) and non-IDUs were examined. We also analysed changes in HIV prevalence among the broader DU population, and drug use-related behaviours including types of drugs used, recent injecting and recent needle sharing in the context of the rapid scale-up of DU sentinel sites and national harm reduction programmes.
FINDINGS: The HIV epidemic among China's DUs is still highly concentrated in five provinces. Here, HIV prevalence peaked at 30.3% [95% confidence interval (CI)=28.6, 32.1] among IDUs in 1999, and then gradually decreased to 10.9% (95% CI=10.6, 11.2) by 2011. We observed a rapid increase in the use of 'nightclub drugs' among DUs from 1.3% in 2004 to 24.4% in 2011. A decline in recent needle sharing among current IDU from 19.5% (95% CI=19.4, 19.6) in 2006 to 11.3% (95% CI=11.2, 11.4) in 2011 was found to be correlated with the rapid scale-up of methadone maintenance treatment (MMT; r(4)=-0.94, P=0.003) harm reduction efforts.
CONCLUSIONS: While HIV prevalence and needle sharing among current injecting drug users in China have declined dramatically and are correlated with the scale-up of national harm reduction efforts, the recent, rapid increased use of 'nightclub drugs' presents a new challenge.
