Epidemiological analysis on acute viral hepatitis in Yangpu district Shanghai from year 2005 to 2007

[目的]分析上海市杨浦区急性病毒性肝炎(急性肝炎)的流行特征,为完善肝炎防治策略和措施提供依据。[方法]对2005—2007年杨浦区网络直报的急性肝炎疫情、病原学分型及专题调查资料进行分析。[结果]2005—2007年杨浦区急性肝炎年均发病率为12.17/10万,其中常住人口年均发病率为11.79/10万,外来人口年均发病率为15.05/10万;五角场和殷行社区发病率最高,年均发病率分别为24.35/10万、23.50/10万;病原学分型显示,网络直报肝炎病例中乙肝比例较低,未定型肝炎比例较高。[结论]2005—2007年杨浦区急性肝炎发病率呈下降趋势,网络直报乙肝病例不全是急性乙肝病例;未定型病例多,主要由误诊、误报、分型信息未及时订正和疾控中心未及时对监测点医院分型情况进行督导等原因引起。

[ Objective] To analyze the epidemiological characteristics of acute viral hepatitis in Yangpu district, Shanghai in order to provide related evidence for perfecting the strategies and measures for the treatment and prevention on hepatitis. [ Methods] The information of the epidemics of acute viral hepatitis and its pathogenic typing obtained directly from computer disease reporting system in Yangpu district, Shanghai during years 2005 - 2007, as well as data on the investigation of special subjects were analyzed. [ Results ] The annual average incidence rate of acute viral hepatitis in Yangpu district from year 2005 to 2007 was 12.17 per 100,000. The annual average incidence rate of permanent residents was 11.79 per 100,000 ,and the annual average incidence rate of floating population was 15.05 per 100,000. The highest incidence rate were in both Wujiaochang and Yinhang regions , where the annual average incidence rate was 24.35 per 100,000 and 23.50 per 100,000, respectively. The pathogenic typing showed that the cases among permanent residents was hepatitis B in direct computer reporting , while the cases of floating proportion was untyped hepatitis. [Conclusion] The incidence rate of acute viral hepatitis in Yangpu district from year 2005 to 2007 shows an declining trend. In the computer disease reporting system, not all the cases of hepatitis B was acute hepatitis B cases. Many of them were untyped eases caused by misdiagnosis, misreporting, or untimely correction of virus typing, when center of disease prevention and control has not carried out well supervision on virus typing in their surveillaneed hospitals.
