目的分析2008-2010年兰州市城关区手足口病流行特征,为制定预防控制手足口病应对措施提供科学依据。方法对2008-2010年国家"疾病监测信息报告管理系统"网络直报的城关区手足口病资料进行流行病学分析。结果 2008-2010年累计报告手足口病3831例,年均报告发病率130.9/10万,不同年份手足口病的报告发病率差异有统计学意义(χ2=121.614,P<0.01);发病时间主要集中在5-7月份,其季节性差异有统计学意义(χ2=360.429,P<0.01);男女比例平均为1.56,差异无统计学意义;手足口病高发于3～4岁的儿童,年龄分布差异有统计学意义(χ2=68.728,P<0.01);以幼托儿童及散居儿童为主,其分布差异有统计学意义(χ2=23.566,P<0.01)。结论手足口病以3～4岁的幼托儿童、散居儿童为重点发病人群,发病时间集中在5-7月份;提示托幼机构是预防手足口病的关键。

OBJECTIVE To analyze the epidemiological characteristics of hand-foot-mouth disease in Chengguan district of Lanzhou from 2008 to 2010,to provide the scientific basis for the anticipatory control of hand-foot-mouth disease.METHODS The epidemiological analysis of the data of hand-foot-mouth disease from National Disease Monitors Information Report Management System was performed through the network straight report from Chengguan district from 2008 to 2010.RESULTS The accumulative total number of reported hand-foot-mouth disease was 3831 with an annual incidence of 130.9/100,000,the difference in the incidence rate of reported hand-foot-and-mouth disease was statistically significant（χ2=121.614,P〈0.01）;the incidence of the diseases mainly distributed during May-Jul,there was no seasonal statistical significance（χ2=360.429,P0.0）;with an average of 1.56 percentage of gender,the difference was not statistically significant;the incidence of hand-foot-and-mouth disease was high in the children aged from 3 to 4 years,the difference in the age distribution was statistically significant（χ2=68.728,P〈0.01）;the vocational childcare and the scattered children were the predominant group,the difference in vocational distribution was statistically significant（χ2=23.566,P〈0.01）.CONCLUSION The incidence of hand-foot-and-mouth disease is high among the children aged from 3 to 4 years and the scattered children,the onset of the diseases mainly distribute during May-Jul;it is suggested that the nursery institution is the key to prevent hand-foot-and-mouth disease.
