[Implementation of intervention programs on AIDS-related sexual transmission in China]

To analyze the implementation of intervention programs targeted on AIDS high risk sexual transmission groups since 2008, when the relative prevention and control information systems on HIV/AIDS were developed.

Data from both aggregated interventions and sentinel surveillance programs from 2008 to the end of 2014 were used. Descriptive statistics were performed to analyze the trends of implementation on high risk groups including men who have sex with men, female sex workers (FSW) and migrant workers.

From 2008 to 2012, the monthly average numbers receiving intervention programs and the average monthly coverage rate on intervention for MSM, increased from 49 000 to 252 000, and from 8.6% to 78.5% respectively. The FSW related indicators increased from 329 000 to 625 000, and from 30.9% to 87.0% respectively. Above indexes on the two populations had dropped slightly in 2013 and 2014. Sentinel surveillance data showed that knowledge and behavior indicators observed from the MSM and FSW populations increased annually. The coverage of intervention programs on migrant workers increased from 4.7% to almost 10.0%, but the surveillance data on migrant men showed that the knowledge and behavior indicators were still lower than the other high-risk groups.

Intervention related to sexual transmission on HIV/AIDS among high-risk populations were effectively implemented, with some achievements seen. However, as sexual contact currently became the main route of AIDS epidemic, new challenges called for serious attention.
