目的对四川出入境人员中抗-HCV阳性者的流行病学调查分析,为采取有效的预防措施,减少丙型肝炎的传播提供参考。方法采用酶联免疫吸附试验(ELLSA),对四川出入境人员中进行抗-HCV检测,检出的阳性标本再用胶体金法复检;对确定为抗-HCV阳性者进行流行病学分析。结果检测总人数8509人,共检出抗-HCV64例。其中中国籍8018人,抗-HCV阳性者62人;外籍人员491人,抗-HCV阳性者2人。劳务人员抗-HCV阳性率最高,为1.09%。有卖血史者抗-HCV阳性占全部阳性的48.39%,感染主要途径与血液感染有关。结论四川出入境人员中劳务人员感染率高,应加强对这一人群关于丙型肝炎预防知识的宣教工作。
Objective To investigate the epidemiological analysis of anti-HCV positive among immigrants entering and exiting Sichuan in order to provide effective preventive measures and reduce the spread of hepatitis C. Methods Enzyme-linked immunosorbent assay (ELLSA) was used to detect anti-HCV in immigrants in Sichuan Province. The positive samples were rechecked by colloidal gold assay. The epidemiological analysis was performed on those positive anti-HCV antibodies. Results The total number of test people was 8509, a total of 64 cases of anti-HCV were detected. Among them, there are 8018 Chinese, 62 anti-HCV positive, 491 foreign nationals and 2 anti-HCV positive. The highest positive rate of anti-HCV in labors was 1.09%. Anti-HCV positive with a history of selling blood accounted for 48.39% of all positive, the main pathways of infection and blood infection. Conclusions The infection rate of labors among Sichuan immigrants is high, so it is necessary to strengthen the missionary work on hepatitis C prevention in this population.
