2017年1月1日至8月31日我国登革热疫情特征阶段性分析

Analysis on epidemiological characteristics of dengue fever in China, as of 31th August,2017

  • 摘要: 目的 针对全国登革热疫情特征进行深入分析,对当前的登革热疫情风险评估提供依据。方法 从我国法定传染病报告信息系统获取病例报告数据,对病例的时间和地区分布进行分析,并分析输入病例的来源国信息以及重点地区的输入病例和本地病例的时间分布情况。结果 截至8月31日,2017年全国累计报告登革热病例1 468例,较2016年同期(831例)上升77%。其中本地病例980例,主要分布在云南省(589例)、浙江省(221例)、广东省(111例)、山东省(58例)和安徽省(1例)。输入病例488例,主要输入国为缅甸(137例)、马来西亚(61例)、泰国(54例)、越南(39例)和斯里兰卡(34例)。云南、广东、浙江和山东省在2017年报告的早期病例均为输入病例。云南省西双版纳州、德宏州和临沧市,浙江省杭州市,广东省广州市和山东省济宁市报告了本地暴发疫情。云南、海南、福建、广西、广东和浙江等高风险省份的布雷图指数大于安全阈值5。结论 截至8月31日我国登革热疫情高于2016年同期,多点出现暴发,甚至扩展至北方省份(山东省济宁市),均为输入病例引发的本地传播。9月我国仍将处于疫情高峰,预计浙江、云南、广东、广西、海南省(自治区)登革热本地传播及暴发风险也将进一步增大。建议各地做好疫情应对工作,北方有伊蚊分布省份也应该重视登革热防控工作。

     

    Abstract: Objective To analyze the characteristics of dengue fever epidemic in China and provide reference to risk assessment of dengue fever epidemic. Methods The incidence data of dengue fever were obtained from the national notifiable communicable disease reporting information system in China for the analysis of the spatial and time distribution of dengue fever cases. The sources of imported dengue fever cases and the time distributions of the imported and indigenous cases were also summarized. Results As of 31th August in 2017, a total of 1 468 cases of dengue fever were reported nationwide, an increase of 77% compared with the same period in 2016 (831 cases). Among them, 980 were indigenous cases, which mainly distributed in Yunnan (589 cases), Zhejiang (221 cases), Guangdong (111 cases), Shandong (58 cases) and Anhui provinces (1 case).The number of imported cases were 488 and the source countries were Myanmar (137 cases), Malaysia (61 cases), Thailand (54 cases),Vietnam (39 cases) and Sri Lanka (34 cases).The early cases of dengue fever of Yunnan, Guangdong, Zhejiang and Shandong provinces were all imported cases. Local outbreaks were reported in Xishuangbanna, Dehong and Lincang in Yunnan province, Hangzhou in Zhejiang province, Guangzhou in Guangdong province, and even Jining in Shandong province. The Brett index of vector density of Yunnan, Hainan, Fujian, Guangxi, Guangdong and Zhejiang and other provinces at high-risk was greater than the threshold of 5. Conclusion As of 31th August, the dengue fever epidemic was more serious in China compared with the same period in 2016, and the northern province of Shandong was also affected. All the local outbreaks were caused by imported cases. The epidemic peak would occur in September with increased epidemic risk in Zhejiang, Yunnan, Guangdong, Guangxi and Hainan provinces. It is suggested to pay attention to dengue fever prevention and control before the epidemic season, even in northern provinces.
