摘　　要：目的了解2005—2013年新乡市甲型病毒性肝炎（甲肝）的流行病学特征，为甲肝防控提供流行病学参考依据。方法对法定传染病报告系统报告的新乡市甲肝发病情况进行描述性流行病学分析。结果2005—2013年甲肝发病率波动在0．49／10万～12．02／10万之间，年均发病率为5．38／10万，2007年最高，以后总体呈下降趋势；发病高峰在7-9月份，农村与城市发病率差异无统计学意义（X2=0．595，P=0．440）。病例以15岁以下儿童为主，占69．96％，男性高于女性（X2=126．553，P=0．000），学生占发病总数的比例最高（34．09％）。其次为农民和散居儿童，分别占23．66％和20．46％。结论建议甲肝防治应采取以预防接种为主，加强疫情监测和开展健康教育的综合性防控措施。Objective This study was to investigate the epidemiological characteristics of hepatitis A in Xinxiang during 2005 to 2013, and to provide scientific basis for the prevention and control of hepatitis A. Methods Descriptive epidemiological analysis was used to analyze the data of viral hepatitis A in Xinxiang from 2005 to 2013 obtained from the Notified Disease Reporting System. Results With an annual average of 5.38/lakh, the incidence of hepatitis A in Xinxiang ranged from 0.49/lakh to 12.02/lakh, which peaked in 2007 and declined gradually afterwards. The peak season was during July to September. There was no statistical difference in the incidence between the urban and rural area （X2=0.595, P=-0.440）. Most patients were younger than 15 years old （69.96%）, and the incidence was higher in males than in females （X2=126.553, P=0.000）. Students contributed the most, with 928 cases and accounting for 34.09% of the total, followed by famers （23.66%） and children （20.46%）. Conclusion It is important to focus primarily on inoculation, and also strengthen surveillance and health education for the prevention and control of hepatitis A.
