为了解丙型肝炎在吸毒人群中的分布状况，本研究采取ＥＬＩＳＡ法对２１９例毒瘤者及９０例对照人群作了抗ＨＣＶ检测。结果发现， ＨＣＶ感染率分别为 ８０．４％和 ６．７％。在毒瘾者中，静脉内毒瘾者、口服毒瘾者和其他形式毒瘾者ＨＣＶ感染率分别为８９．７％、２３．７％、３３．３％；静脉内毒瘾者的ＨＣＶ感染率与其他各组差异有极显著性意义（Ｐ＜０． ００５），表明它是 ＨＣＶ感染的高危人群；不同年龄段毒瘾者 ＨＣＶ感染率明显相关，而不同性别间差异则无显著性意义；毒瘾者的ＨＣＶ感染率随吸毒年限、注射毒品次数的增加而呈上升趋势；对毒瘾者ＨＣＶ感染的危险因素分析表明：静脉内毒瘾、注射溶剂、皮肤不消毒、戒毒次数等是主要的危险因素。
In order to understand the distribution of hepatitis C in drug addicts, ELISA was used to detect anti-HCV in 219 cancer patients and 90 control subjects. The results showed that HCV infection rates were 80.4% and 6.7%. Among drug addicts, the prevalences of HCV infection were 89.7%, 23.7% and 33.3% in intravenous drug addicts, oral drug addicts and other forms of drug addicts; HCV infection in intravenous addicts Rates were significantly different from other groups (P <0. 005), indicating that it is a high risk group of HCV infection; different ages of drug addicts were significantly related to the prevalence of HCV infection, but no significant difference between genders . The prevalence of HCV infection among drug addicts increased with the increase of drug addiction and the number of drug injections. The analysis of risk factors of HCV infection among drug addicts showed that: intravenous drug addiction, injection of solvent, non-sterilized skin, The main risk factors.
