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 review the reported cases of hepatitis B (hepatitis B) in 2010 in six counties (autonomous regions and municipalities) in Henan Province, and to clearly report the characteristics of hepatitis B cases and explore the causes of the high incidence of hepatitis B. Methods According to the reports of hepatitis B in all counties in the province, the incidence rate was high, middle and low were divided into three layers, and two counties were taken from each layer. The report system of hepatitis B from 2008 to 2010 in six counties was derived and analyzed. The current year and inter-annual reports of cases were checked and checked, see 2010 cases and the first two years of re-reporting and possible re-rate. Results A total of 10 025 cases of hepatitis B cases were reported in six counties in 2010, of which 58.60% were diagnosed in laboratory, 36.72% were carriers of HBsAg, 0.03% were detected in suspected cases, and 0.03% were detected in clinical diagnosis, respectively % And 4.21%. 6297 cases of laboratory diagnosis and clinical diagnosis of hepatitis B cases, acute hepatitis B accounted for 2.13%, chronic hepatitis B accounted for 73.46%, unclassified hepatitis B accounted for 24.41%; the year 2010 and the first two years of repay and may re-report 1181 cases of hepatitis B cases, Accounting for 18.75% of the reported cases of hepatitis B in six counties, of which 14.51% were re-reported and 4.24% re-reported. The reported incidence of hepatitis B in the six counties was as high as 36.03 / 100000. Conclusion It is one of the important reasons for the high incidence of hepatitis B that the retransmission and possible retransmission of cases are caused.
