目的分析宁波市2008—2012年手足口病的流行特点,探讨其空间聚集特征。方法综合流行病学方法和空间自相关分析方法,以区县级为单位对宁波市2008—2012年手足口病监测数据进行分析。结果 2008—2012年宁波市共报告新发手足口病63 213例,年均报告发病率为173.72/10万;发病以男性居多,男女占比达1.57∶1;年龄分布以低龄儿童为主,5岁以下占90.35%,3岁以下占60.28%;职业分布以散居儿童为主(63.39%),其次是幼托儿童(34.44%)和学生(2.16%);发病率地区分布和空间自相关分析结果表明宁波市南部的宁海县与象山县为手足口病高发病率聚集地区。结论宁波市手足口病持续高发,发病率高于浙江省平均发病率;宁波市南部的宁海县和象山县是主要发病聚集区域。
Objective To analyze the epidemiological characteristics of hand-foot-mouth disease in Ningbo City from 2008 to 2012 and discuss the characteristics of its spatial aggregation. Methods Based on epidemiological methods and spatial autocorrelation analysis, the monitoring data of hand-foot-mouth disease in Ningbo City from 2008 to 2012 were analyzed by district and county. Results A total of 63 213 new-onset HFMD cases were reported in Ningbo from 2008 to 2012, with an average annual incidence of 173.72 / 100 000. Most of the patients were male, accounting for 1.57:1. The distribution of age was mainly young children, 90.35% under 5 years old and 60.28% below 3 years old. The occupational distribution mainly consisted of scattered children (63.39%), followed by child care children (34.44%) and students (2.16%). The distribution of regional incidence and spatial autocorrelation The results of the analysis show that Ninghai County and Xiangshan County in southern Ningbo are areas with high incidence of HFMD. Conclusions Hand-foot-mouth disease in Ningbo City is still high and the incidence rate is higher than the average incidence rate in Zhejiang Province. Ninghai County and Xiangshan County in the south of Ningbo City are the main areas for the incidence of HFMD.
