深圳市某区2005-2008年甲乙类肠道传染病疫情动态分析

Dynamic Analysis on Epidemic Situation of Type A and B Intestinal Infection Diseases in a Certain District of Shenzhen from 2005 to 2008

目的了解肠道传染病的发病特征及流行趋势,为制订肠道传染病防治策略提供科学依据。方法对深圳市龙岗区2005-2008年的肠道传染病疫情资料进行描述性流行病学分析和相关分析。结果2005-2008年,深圳市龙岗区共报告甲乙类肠道传染病7种2761例,年平均报告发病率为43.49/10万,占法定传染病报告发病总数的7.09%;5岁以下儿童高发,占肠道传染病报告发病总数的37.20%;甲乙类肠道传染病发病率(r=0.45,P=0.01)和痢疾发病率(r=0.44,P=0.01)与蝇密度相关密切,但与蟑螂密度无显著相关(P<0.05)。结论深圳市龙岗区肠道传染病的发病还处于较高水平,应重点加强儿童尤其是1岁以下婴幼儿细菌性痢疾的预防与控制。

Objective To understand the characteristics and prevalence tendency of intestinal infection diseases, and to provide a scientific basis for infection disease control and prevention. Methods Descriptive epidemiological analysis and correlation analysis were used for information on reported intestinal infection diseases in Longgang District of Shenzben City from 2005 to 2008. Results There were 7 kinds of intestinal infection diseases and 2,761 cases reported in Longgang District from 2005 to 2008, with the average annual incidence of 43.49/100,000, which accounted for 7.09 % of the total communicable disease reporting. Children below 5 years were the main susceptible population which accounted for 37.20% of the total intestinal infection disease reporting. The incidence rates of Type A and B intestinal infection diseases （r = 0.4.5, P = 0.01） and dysentery （r = 0.44, P = 0.01） were closely related to the density of fly, but not related to the density of cockroach （P〈0.05）. Conclusions The prevalence rate of intestinal infection diseases in Longgang District is still at a relatively high level, and more attention should be paid for dysentery prevention for children, especially infants below 1 - year- old.
