目的分析高县病毒性肝炎流行病学趋势,为制定控制策略提供科学依据。方法对高县1980~2012年病毒性肝炎疫情资料,采用描述性流行病学分析方法进行统计分析。结果 1980~2012年共报告病毒性肝炎11 748例,死亡17例,年均发病率为75.26/10万,年均死亡率0.11/10万。发病率最高年份为1986年(230.89/10万),最低年份为2010年(26.06/10万)。1980~1991年发病6 495例,占报告病例总数的55.66%,年均发病率为118.26/10万,1992~2012年间年均发病率为51.92/10万,趋势卡方检验(P<0.01)。累计各年每月均有病例发生,少年和青壮年农民发病占总病例数的71.37%,男女病例性别比1.93∶1。结论高县病毒性肝炎无明显季节高峰,以少年和青壮年农民发病为主。1992~2012年间发病率呈逐年下降趋势,提示病毒性肝炎防治取得明显成效。
Objective To analyze the epidemiological trends of viral hepatitis in high counties and provide a scientific basis for the development of control strategies. Methods The data of epidemic situation of viral hepatitis in high counties from 1980 to 2012 were analyzed by descriptive epidemiological analysis. Results A total of 11 748 cases of viral hepatitis and 17 cases of death were reported from 1980 to 2012, with an average annual incidence of 75.26 / 100 000 and an annual average mortality of 0.11 / 100 000. The highest incidence in 1986 (230.89 / 100,000), the lowest year of 2010 (26.06 / 100,000). The incidence was 6 495 from 1980 to 1991, accounting for 55.66% of the total reported cases, with an average annual incidence of 118.26 / 100 000. The average annual incidence was 51.92 / 100 000 between 1992 and 2012. The trend chi square test (P <0.01) . Cumulative monthly incidence of cases every year, juvenile and young farmers accounted for 71.37% of the total number of cases, male and female cases of sex ratio of 1.93: 1. Conclusion There is no obvious seasonal peak in high-grade viral hepatitis, with the onset of juvenile and young peasants being the main factor. The incidence rate showed a declining trend from 1992 to 2012, suggesting that the prevention and treatment of viral hepatitis achieved remarkable results.
