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 epidemiological characteristics of hepatitis A virus (A) in Jingmen City and to provide a theoretical basis for making further strategies and measures to reduce it. Methods The trend of incidence in 1992-2009 was fitted by curve, and the distribution characteristics of cases from 2004 to 2009 were analyzed by epidemiological method. Results The incidence of hepatitis A in Jingmen decreased year by year. The fitted power function model was Y = 270.3X-1.3061. The seasonal distribution was not obvious. The highest incidence was found in hilly areas, followed by the plains, the lowest in urban areas and the lowest in urban areas. , Farmers, students are high incidence of hepatitis A population. Conclusion The implementation of previous prevention and control measures, the incidence will remain at a low level. The key to preventing and controlling hepatitis A in the next stage is to control outbreaks. The key prevention and control population is students and young farmers.
