河南省六个县(区)2010年报告乙型病毒性肝炎病例分析

Analysis on Hepatitis B in Six Counties/Districts in Henan Province in 2010

目的审核河南省六个县(区,下同)2010年报告的乙型病毒性肝炎(乙肝)病例,明确报告乙肝病例的特征,探索乙肝高发病率的原因。方法根据全省各县乙肝报告发病率高、中、低分为三层,每层抽取两个县;在监测系统中导出六个县2008～2010年的乙肝报告卡进行分析,同时对报告卡分别进行当年和跨年度报告病例查重,查看2010年病例中当年和前2年的重报和可能重报率。结果2010年六个县共报告乙肝病例卡10 025张,其中实验室诊断病例占58.60%,乙肝病毒表面抗原携带者占36.72%,疑似病例、检测阳性者和临床诊断病例分别占0.03%、0.44%和4.21%。6297例实验室诊断和临床诊断乙肝病例中,急性乙肝占2.13%,慢性乙肝占73.46%,未分类乙肝占24.41%;2010年当年及前2年的重报和可能重报乙肝病例1181例,占六个县报告乙肝病例的18.75%,其中重报占14.51%,可能重报占4.24%,重报和可能重报使六个县乙肝平均报告发病率虚高36.03/10万。结论病例的重报和可能重报是导致乙肝发病率虚高的重要原因之一。

Objective To analyze the characteristics of virus B hepatitis in Henan province in 2010 and explore the reasons of high infectious rate. Methods All of the counties and districts were divided into three parts based on hepatitis B infectious rate（high, moderate or low）, one county and one district were collected from each part. The data of hepatitis B was analyzed during 2008-2010 and the proportion of repetitive reports and potential repetitive reports was explored in 2010 and two years before. Results 10 025 reporting cards of hepatitis B were reported in six counties/districts in 2010, 58.60%of cases were diagnosed by laboratory and 36.72 %were Hepatitis B virus surface antigen carriers, the suspected, positive and clinically account for 0.03%, 0.44%and 4.21%respectively. 6, 297 cases were diagnosed by laboratory or clinical, the chronic and unclassified account for 2.11%, 73.46%and 24.41% respectively. During 2008-2010, 1, 181 （18.75 % ）cases were reported repetitively. The repetitive and probably repetitive reports account for 14.51%and 4.24% respectively. The average reported incidence was increased of 36.03/100, 000 in error because of the repetitive and probably repetitive reports. Conclusions The repetitive and probably repetitive reports was one of the most important reasons of the high hepatitis B infectious rate.
