目的了解慢性丙型肝炎患者感染途径并进行流行病学分析,为中国慢性丙型肝炎的预防提供基础资料。方法本研究采用问卷的形式,调查患者的年龄、性别、感染途径等,并进行流行病学分析。结果 1 129例慢性丙型肝炎患者中,输血及血制品感染者,占61.2%,感染途径不详者占32.8%,吸毒者3.9%;与丙肝患者密切接触者1.6%,性行为0.5%;不同性别间感染途径比较差异有统计学意义,(χ2=36.695,P<0.01);不同年龄段感染途径比较差异有统计学意义,(χ2=98.281,P<0.01);南北方城市感染途径比较差异有统计学意义,(χ2=34.594,P<0.01)。结论慢性丙型肝炎的感染途径主要以输血及血制品使用为主,不同性别、年龄段、地域慢性丙型肝炎的感染途径存在明显差异。
Objective To understand the pathways of infection in patients with chronic hepatitis C and conduct epidemiological analysis to provide basic information for the prevention of chronic hepatitis C in China. Methods In this study, the questionnaire was used to investigate the patient’s age, sex, infection route and so on, and to conduct epidemiological analysis. Results Among the 1 129 chronic hepatitis C patients, 61.2% were infected with blood transfusions and blood products, 32.8% were infected with unknown pathogens, 3.9% were drug users, 1.6% were in close contact with hepatitis C and 0.5% were sexually transmitted. (Χ2 = 36.695, P <0.01). There were significant differences in infection pathways between different sexes (χ2 = 98.281, P <0.01). There were significant differences in the pathogenic ways of infection between southern and northern cities There was statistical significance (χ2 = 34.594, P <0.01). Conclusion The main routes of infection of chronic hepatitis C are mainly blood transfusion and blood products. Significant differences exist in the infection ways of chronic hepatitis C among different sexes, ages and regions.
