我国病毒性肝炎发病数和发病率的变化过程及发展趋势

Changing Process and Development Trend of the Incident Number and Morbidity of Viral Hepatitis in China

目的重点分析我国实行传染病网络直报系统后病毒性肝炎的年发病数和发病率变化过程及发展趋势。方法采用描述统计分析、移动平均分析等方法,对我国政府部门1992-2013年间公布的法定传染病报告进行分析。结果近年及未来一个时期,病毒性肝炎的发病数(率)仍处于较高水平,在甲乙类传染病中居前列;乙肝的发病数(率)虽呈现下降趋势,但仍占病毒性肝炎的相当大比例;丙肝发病数(率)11年里增长了近10倍,近年来增长速度有所减缓;甲肝和未分型肝炎发病数(率)呈逐年下降趋势;戊肝发病数(率)仍维持在较低水平。结论我国对病毒性肝炎的防治取得了显著成效,未来除对甲肝、乙肝仍需高度关注外,应进一步加强对丙肝的防治。

Objective To analyze the changing process and development trend of the incident number and morbidity of viral hepatitis after the implementation of the Internet-based National Notifiable Infectious Disease Reporting System. Methods Descriptive and moving average methods were used to analyze the data in the report of notifiable infectious diseases publicly released by the department of our government during 1992-2013. Results In recent years and one period in future, the incident number and morbidity of viral hepatitis is still at a high level and stays at the forefront among all the reported A and B infectious diseases; the incident number and morbidity of Hepatitis B has declined, but it still accounts for a great proportion of viral hepatitis; the incident number and morbidity of Hepatitis C has increased by nearly 10 times in 11 years, but the growth rate shows a slight decrease; the incident number and morbidity of Hepatitis A and unclassified hepatitis show different degrees of decline; the incident number and morbidity of Hepatitis E stabilizes at a relatively low level. Conclusion The results showed that prevention of viral hepatitis in our country has got a remarkable achievement. Except for paying attention to the prevention and treatment of Hepatitis A and B, the relevant department should further strengthen the prevention and treatment of Hepatitis C in future.
