Abstract: 【Objective】 To understand the epidemic features of chickenpox in China from 2007-2010 by using the geographical epidemiology methods. 【Methods】 Using the surveillance data from national internet-based information system of infectious diseases in China Disease Prevention and Control Center, the analysis of the status of chickenpox epidemic in China from 2007 to 2010 was conducted by GIS software(ArcGIS) and statistical software(Stata). 【Results】 the national average incidence of chickenpox was 20.6, 23.8, 24.1, and 24.3 per 100 000 populations in 2007-2010 respectively. Using the cases/incidence of chickenpox in 2010 as an example, there were 162 counties which incidence of chickenpox was higher than 100/100 000. Most of them were located in Tebit, Xinjiang, Sichuan, Liaoning, Guangdong, Gansu provinces and accounted for 52% of 162 counties. From 2007 to 2010, the incidence of chickenpox increased yearly. 【Conclusions】 The risk factors of chickenpox epidemic are different among the provinces. The prevention strategies should be developed based on the local situation.

摘要： 【目的】 从地理流行病学的角度了解我国2007-2010年水痘发病情况。 【方法】 使用中国疾病预防控制中心“疾病监测信息报告管理系统”,ArcGIS地理信息系统软件,Stata统计分析软件对2007-2010年全国水痘疫情分布进行了分析。 【结果】 2007-2010年全国平均发病率分别为十万分之20.6、23.8、24.1、和24.3,以2010年为例,发病率大于100/10万共有162的县,多数集中在西藏、新疆、四川、辽宁、广东、甘肃六个省,占总数的52%。2007-2010年全国水痘病例报告的人数和平均发病率的有逐年增高的趋势。 【结论】 水痘发病的地域区别较大,影响发病率的因素较多,各地应根据自身情况与实际特点有针对性的进行防控。
