[ Results] The positive rate of HIV anti- body among drug users was 33.66%, HIV infection rate showed a decreasing trend annually （ X2 =33.16, P 〈0.01 }. The propor- tion of injection drug addicts also showed a decreasing trend annually, and the difference was significant（ x2 = 18.54,P 〈0.01 ）. The diflerence of HIV infection between drug addicts with syringes sharing and drug addicts without syringes sharing was significant （x2 = 17.46, P 〈 0.01 ）. 30.16% had ever had sex with others by trading with money or drug, only 16.80% of them used con- doms each time and the proportion as high as 52% had never used condoms.
