摘要
目的分析荆门市甲型病毒性肝炎(甲肝)的流行特征,为制定进一步降低的策略和措施提供理论依据。方法对1992-2009年的发病趋势进行曲线拟合,采用流行病学方法对2004-2009年的病例分布特征进行分析。结果荆门市甲肝报告发病呈逐年下降趋势,拟合幂函数模型为:Y=270.3X-1.3061;季节分布不明显;丘陵地区发病率最高,平原地区、山区次之,城市地区最低;青壮年人群、农民、学生是甲肝的高发人群。结论落实既往防控措施,发病率将保持在较低水平。下一阶段防控甲肝的关键是控制暴发流行,防控的重点人群是学生及青壮年农民。
Objective To analyze the epidemiologic features of viral hepatitis A in Jingmen and provide theoretical basis to formulate strategies and measures for further reducing the incidence rate of viral hepatitis A.Methods Make the curve fitting on the trend during 1992-2009,and use epidemiological method to analyze the case distribution during 2004-2009.Results The reported incidence rate of viral hepatitis A in Jingmen had a downward trend with the fitting power function model：Y=270.3X-1.3061;which had no obvious seasonal distribution;the highest incidence rate was in hilly areas,in turn,the plain and mountainous,and the lowest was in urban areas;it was found that young people,farmer and students had the higher risk of being infected.Conclusions The incidence rate will still remain at low level if the existing preventive measures were well implemented.The key point in the next stage is to control the outbreak of hepatitis A,and priority will be put on the students and young farmers.
