Epidemiological analysis of intestinal infectious diseases in Jiangshan county of Zhejiang province,2004-2007

目的了解浙江省江山市近年肠道传染病流行趋势和特点。方法采用描述流行病学方法,对江山市2004-2007年法定报告肠道传染病发病、死亡资料进行统计分析。结果4年间共报告法定肠道传染病8种1639例,年平均发病率82.77/10万,占法定传染病报告总数的16.97%,无死亡病例。其中菌痢、副伤寒发病率波动较大,甲型肝炎(甲肝)、戊型肝炎(戊肝)、肝炎(未分型)、阿米巴性痢疾、伤寒等发病率相对稳定,其他感染性腹泻病发病呈逐年上升趋势。男性报告发病1075例,女性564例,性别比为1.91∶1,0～5岁(691)和15～49岁(559)年龄组发病分别占42.16%、34.11%。职业以散居及幼托儿童(44.91%)、农民(26.85%)、学生(12.08%)为主,季节以夏秋季多发。结论江山市肠道传染病发病率较低,但有上升趋势,高度散发,时有点状暴发,今后应进一步加强综合防制工作,并密切关注其他感染性腹泻病的流行动态。

Objective To investigate the epidemic trend and features of intestinal infectious diseases in Jiangshan city in recent years, and provide evidence for the development of strategy for effective prevention and control of intestinal infection. Methods The descriptive epidemiological method was employed to statistically analyze the epidemic data of intestinal notifiable infectious diseases and death reports in Jiangshan city from 2004 to 2007. Results A total 1639 cases of 8 intestinal infectious diseases were reported during the past four years with an average annual incidence rate of 82.77/lakh, accounting for 16.97% of the total cases of notifiable infectious diseases. No death case was reported. Though the incidence of bacillary dysentery and paratyphoid varied greatly, the incidence of hepatitis A, hepatitis E, hepatitis （unspecified）, amebic dysentery and typhoid remained stable, and the incidence of other infectious diarrhea increased year by year. A total of 1075 male eases and 564 female cases were reported with the gender ratio of 1.91 ： 1. The cases in age group 0-5 years （691 cases） and age group 15-49 years （559 cases） accounted for 42.16% and 34.11%, respectively, of the total cases. As for the population distribution, scattered and preschool children （44.91%）, farmers （26.85%） and students （12.08%） comprised the major affected group. The onset peaks were seen in summer and fall. Conclusion The incidence of intestinal infectious diseases was low in Jiangshan city, though an increasing trend was observed with highly scattered and spot- outbreak characteristics. The comprehensive prevention and control of intestinal infectious disease should be further strengthened and the prevalence of other infectious diarrhea should be monitored.
