凉山州吸毒人群HIV和HCV感染情况调查

目的了解吸毒人群中人类免疫缺陷病毒（HIV）和丙型肝炎病毒（HCV）共感染情况以及影响其感染的因素。方法对四川省凉山地区356名吸毒人员进行流行病学调查，并检测其HIV和HCV抗体。结果356名吸毒人员中HCV抗体阳性者210例，占59．0％；HIV抗体阳性者31例，占8．7％，其中同时感染HIV和HCV者25例，占7．0％；少数民族和受教育程度低的吸毒人群中HIV的感染明显高于其他人群（P〈0．05）。采取静脉共感染注射吸毒的人群中HCV的感染者高于其他人群，且差异有统计学意义（P〈0．001）。结论通过提高其文化水平减少吸毒人群，或改变吸毒方式，可以控制或减少HIV和HCV的传播和扩散。

Investigation on infection status of HIV and HCV in drug user in Liangshan area

Objective To study the prevalence of human immunodeficiency virus(HIV) and hepatitis C virus(HCV) coinfection and to identify possible risk factors for its transmission,in 356 adults drug users in Liangshan area,Sichuan province. Methods The anti-HIV and anti-HCV was performed by ELISA,besides the mode of taking the drug,educational degree and nationality were also surveyed. Results The proportion of HCV infection was 59.5%(210 cases),31 cases(8.7%) were solely infected with HIV and 25(7.0%) cases were coinfected with HIV and HCV.In both minor nationality and lower educational degree druggers,the overall prevalence of HIV infection was higher than other people(P<0.05) and with statistically significant difference between them.The risk of HCV infection of injecting drug users was significantly more than that of oral drug users(P<0.001). Conclusion Decreasing the drug user by improving the education level or changing the way of drug using could reduce the infection and spread of HIV and HCV.
