| 目的 分析2015-2018年我国登革热暴发流行病学特征，为制定登革热防控策略提供参考。方法 收集和分析中国疾病预防控制信息系统、突发公共卫生事件报告管理信息系统及病媒生物监测系统上报的登革热发病及媒介监测数据，描述登革热暴发流行病学特征。应用Excel 2010和SPSS 20.0软件整理数据和分析，采用ArcGIS 10.5软件绘制地图。结果 2015-2018年全国累计报告登革热暴发111起，共涉及病例12 490例，占全国病例总数的73.7%。暴发集中在广东（77起）、云南（14起）、浙江（8起）和福建（8起）4省份，共累及85个县（区）。暴发集中在5-11月，病例≤ 10例的小规模暴发多于30 d内终止（28/34，82.4%），较大规模暴发多持续数月，于10-11月终止。登革病毒1型和2型为我国登革热暴发的主要流行株。疫情主要发生在人口密度大、卫生环境差的区域。主要暴发省份病例的年龄和职业构成差异有统计学意义。结论 我国登革热暴发呈地域扩散、甚至向高纬度扩散态势，不同省份暴发特征各异，总体分为口岸型、乡村型和城市型，各省份应针对性调整防控策略。 |

| Objective To analyze the epidemiological characteristics of outbreaks of dengue fever in China from 2015 to 2018, and provide evidence for the prevention and control of dengue fever. Methods We extracted the incidence data of dengue fever from China Disease Prevention and Control Information System, Public Health Emergency Reporting Management Information System and Vector Biological Monitoring System, and explored the epidemiological characteristics of the outbreaks in the past four years. Excel 2010 software and SPSS 20.0 software were used for data processing and analysis, ArcGIS 10.5 software was used for mapping. Results A total of 111 outbreaks of dengue fever were reported nationwide from 2015 to 2018, involving 12 490 cases, accounting for 73.7% of the total cases in China. These outbreaks occurred in 85 counties and districts of 4 provinces, namely Guangdong (77 outbreaks), Yunnan (14 outbreaks), Zhejiang (8 outbreaks) and Fujian (8 outbreaks). The outbreaks occurred during May-November. Small-scale outbreaks with no more than 10 cases ended within 30 days (28/34, 82.4%) and larger-scale outbreaks lasted for several months. Dengue virus type 1 and type 2 were the main epidemic pathogens of dengue fever outbreaks in China. The outbreaks mainly occurred in areas with high population density and poor sanitary environment. There were significant differences in the age and occupational composition of the cases in the main outbreak provinces. Conclusions Outbreaks of dengue fever can been seen in more areas in China, even in high latitudes areas. The epidemiologic characteristics of the outbreaks were different among provinces, showing as port type, rural type and urban type. Each province should adjust the control strategies accordingly. |
