摘要 目的分析广东省近年来登革热疫情特点及流行规律,为制定预防控制措施提供依据。方法收集广东省2001-2006年登革热疫情资料,用描述性流行病学方法分析其流行特征和流行因素。结果2001-2006年广东省共报告登革热本地病例2 897例,报告外地病例320例,年发病率在0.01/10万-1.77/10万之间。疫情涉及12个市,主要集中于广州(73.89%)、汕头(6.99%)、阳江(5.10%)、中山(4.78%)等市。3-12月均有病例报告,6-11月为流行期,8-10月为发病高峰期(占88.90%)。男女性别比例为1∶1.07;各年龄组均有发病,但发病数以15-54岁年龄组居多(占73.72%),发病率以20-44、60-69岁年龄人群居高;职业以家务及待业、农民、学生、工人和离退人员为主。每年均有国外输入病例报告,病例输入地主要以新加坡、印尼、柬埔寨等东南亚地区为主。51起本地暴发疫情中,除1起疫情为登革Ⅱ型病毒引起外,其余均为登革Ⅰ型病毒引起。结论广东省登革热仍为输入或输入引起的本地传播的传染病,珠江三角洲和粤东地区应为广东省登革热预防控制的重点地区。 Objective To analyze characteristics and risk factors of dengue fever and provide evidence for followed actions of prevention and control Methods Descriptive statistical methods were used on epidemiological data of dengue fever between 2001 and 2006 to analyze features and related factors of epidemic. Results A total of 2 897 local cases were reported as well as 320 external cases in Guangdong province between 2001 and 2006. The incidence was from 0.01 to 1.77 per 100 thousands annually. Cases were found in 12 dries but clustered in areas of Guangzhou, Shantou, Yangjiang, Zhongshan, et al. and spotted from March to December. Epidemic sustained from June to November and peaked from August to October. The male/female ratio is 1: 1.07. Every age group had reported cases and the majority were in 15 - 54 years group. The incidence grew high in 20 - 44 and 60 - 69 years group. Most cases were household workers, workers waiting for employment, poasants, students, ordinary workers and retired workers. Imported cases from foreign countries were reported each year which were mainly imported from southeast-Asia countries such as Singapore, Indonesia, Cambodia, et al. Primary serotype of dengue virus caused endemic outbreaks was type Ⅰ strain. Conclusion The dengue fever epidemics of Guangdong were closely related to imported cases or importer-induced endemic prevalence and control efforts should focused on Pearl River Delta and east areas of province.
