Epidemic characteristics of hepatitis C in Shenzhen, 2008-2017

Abstract

Objective To explore the epidemic characteristics and trend of hepatitis C in Shenzhen, and to provide a theoretical basis for effective strategy for general prevention and control of hepatitis C. Methods The incidence data of hepatitis C in Shenzhen during 2008-2017 were collected from national diseases reporting information system from Chinese Information System for Diseases Control and Prevention to conduct descriptive epidemiological analysis. Results A total of 18 671 cases of hepatitis C reported in Shenzhen from 2008 to 2017, and the incidence ranged from 14.16/100 000 to 22.31/ 100 000, the average incidence rate was 18.54/100 000. It showed low morbidity, no death, no agglomeration, no obvious seasonal high incidence, but the overall incidence showed a slow upward trend. All ages had morbidity, and the cases were mainly concentrated in the 20-50 age group. The annual incidence of the 0-year-old group in Shenzhen was maintained at around 15 cases, and the incidence of the under 10 years old group accounted for 1.2% of all cases. The population of hepatitis C in Shenzhen were mainly due to household chores and workers. Conclusion The incidence of hepatitis C in Shenzhen is mainly dominated by young, middle- aged and household chores, workers people. At the same time, mother- to- child transmission is also one of the important ways for hepatitis C transmission in Shenzhen. Therefore, we will continue to carry out health education and risk behavior interventions for the prevention and treatment of hepatitis C infection in migrating populations, enhance their awareness of prevention, reduce behavioral risks and conduct prenatal examinations. The implementation of hepatitis C maternal and child blockade is the most effective way to prevent and control hepatitis C in Shenzhen. 摘要： 目的 分析深圳市丙肝发生、流行特征及变化趋势, 为制定有针对性的丙肝防控措施提供理论依据。 方法 对中国疾病预防控制信息系统“传染病报告信息管理系统” 2008—2017 年报告的深圳市丙肝病例信息进行描述 性分析。 结果 深圳市 2008—2017 年累计报告丙肝病例数18 671例, 发病率在14.16/10万~22.31/10万之间, 年均发病 率18.54/10万, 呈现出无死亡、无聚集性疫情、无明显季节性高发的散发特征, 但总体发病呈缓慢上升趋势。各年龄组 均有发病, 病例主要集中在20~50岁年龄组。深圳市0岁组年发病数维持在15例左右, 10岁组以下的发病占到全部病 例数的1.2%。深圳市丙肝发病人群主要以家务待业及工人为主。 结论 深圳市丙肝的发病主要以青壮年劳务工和家 务待业人群为主; 同时, 母婴传播也是深圳市丙肝传播的主要途径之一。因此, 持续开展针对流动人群丙肝感染防治 知识的健康教育和危险行为的干预, 增强其防范意识, 降低行为风险以及开展母婴阻断是深圳市预防和控制丙肝的最 有效的手段。
