ANALYSIS ON HIV/AIDS MONTORING RESULTS OF DRUG USERS IN CHANGZHOU CITY FROM 2005 TO 2007

[Objective] To learn about the epidemiological distribution, HIV infection rate, syphilis positive rate and HCV infection rate among drug users in Changzhou City. [Methods] Serological ELISA was conducted to determine HIV anti-bodies in serum and positive samples during the first round of screening were sent to Jiangsu CDC for identification; ELISA and rapid plasma reagin circle card test (RPR) were used to detect syphilis antibodies. ELISA was conducted to determine HCV an-tibodies. [Results] A total of 855 drug users were tested in these 3 years. The positive rate of HIV, HCV and Syphilis (RPR) was 2.2%, 50.8% and 4.8% respectively.68.0% of drug users had ever injected drug, of which 43.5% had ever shared needles with others. 25% had commercial sexual behavior, of which 18.8% used condom in the last sex. [Conclusion] The HIV infec-tion rate is low in native drug users and high in migrant ones. Health education and behavior intervention for drug users should be enhanced, especially in migrant drug users, to reduce the needles sharing and improve the condom use in commercial sex. The education of standing off drug should be enhanced among juveniles.
