【摘要】 目的分析我国2016年登革热流行特征,对比输入及境内感染病例差异,为登革热防控提供思路与建议。方法根据"中国疾病预防控制信息系统"上报的登革热发病数据,描述病例的人口学和流行病学特征,比较输入性和本地感染疫情的时空分布,呈现境外输入性疫情的来源。结果 2016年全国累计报告登革热病例2 049例(无死亡),较2015年同期下降46.9%,年报告发病率0.2/10万。其中,境内感染病例1 569例(76.6%):本地感染病例1 562例,集中于福建省(921例)、广东省(416例)、云南省(217例)和浙江省(8例);外省输入病例7例,分布于广西壮族自治区和湖南省(各2例)、山东省、陕西省和浙江省(各1例)。23省份报告了境外输入病例480例(占全部病例的23.4%),主要来源于东南亚和南亚(434例,占境外输入病例的90.4%)。结论 2016年我国登革热疫情较2015年显著下降,疫情仍以输入疫情导致本地暴发为主,本地疫情集中于既往高发省份,本地和境外输入性病例的流行病学特征差异显著。我国应根据输入和境内感染病例流行病学特点,完善登革热防控策略。更多还原

【Abstract】 Objective To analyze the epidemiological characteristics of dengue fever in 2016 and compare the difference between imported and indigenous dengue fever cases in China,and provide evidence for the development of national strategies for dengue fever prevention and control. Methods The incidence data of dengue fever were obtained from national notifiable communicable disease reporting information system to describe the demographic and epidemiological characteristics of the dengue fever,and the spatiotemporal patterns were compared between imported and indigenous cases,and the imported sources of dengue fever were also presented. Results In 2016,a total of 2 049 dengue fever cases were reported without death in China,a decrease of 46. 9% compared with 2015. The incidence rate was 0. 2/100 000. Among the reported cases,1 569 were indigenous cases( 76. 6%). A total of 1 562 local cases were reported in Fujian( 921 cases),Guangdong( 416cases),Yunnan( 217 cases) and Zhejiang( 8 cases); and 7 cases from other provinces were reported by Guangxi and Hunan( 2 cases respectively),and Shandong,Shaanxi and Zhejiang( 1 case respectively). A total of 480 imported cases were reported in 23 provinces,accounting for 23. 4% of total cases,in which 434 were from Southeast Asia and South Asia,accounting for 90. 4% of total imported cases. Conclusion The incidence of dengue fever was significantly lower in China in 2016 compared with 2015,and the indigenous outbreaks in provinces with high incidence history were mainly caused by imported cases. The significant difference in epidemiological characteristics has been found between indigenous and imported cases. Therefore,it is necessary to improve the dengue fever control strategy according to the characteristics of indigenous and imported dengue fever cases.更多还原
