Abstract

Abstract: Objective To investigate the epidemiological characteristics of transborder imported dengue fever cases in Yunnan province, China, and to provide guidance for the prevention and control of transborder imported dengue fever cases in Yunnan province. Methods Data of imported dengue fever cases in Yunnan province were obtained from the Infectious Disease Report Information Management System of China Information System for Disease Control and Prevention; Excel 2016 software was used for data collation and plotting; SPSS 19.0 software was used for statistical analysis and processing of the data; ArcGIS 10.5 software was used to plot the geographical distribution of imported dengue fever cases. Results From 2005 to 2019, there were 4 660 transborder imported dengue fever cases in Yunnan province, of which Southeast Asia cases accounted for 98.99% (4 613/4 660) and Myanmar’s cases accounted for 86.06% (3 970/4 613) of the total number of imported cases from Southeast Asia. Among the imported cases from Myanmar, the number of dengue fever cases imported into Dehong Dai and Jingpo Autonomous Prefecture accounted for 62.04% (2 463/3 970), and the cases imported in October as the peak month accounted for 35.49% (1 409/3 970). Among the imported cases from Myanmar, there were slightly more males than females, with a male-to-female sex ratio of 1.19:1; 21-30-year-old cases had the largest proportion among all age groups, accounting for 27.71% (1 100/3 970); farmers and business service providers were the main occupations, accounting for 42.95% (1 705/3 970) and 21.49% (853/3 970), respectively. Conclusion The risk of imported dengue fever in the border areas of Yunnan province is relatively high. It is recommended to reinforce joint prevention and control, strengthen the education on prevention and control of dengue fever for key groups of local residents and enhance the surveillance of imported dengue fever cases as well as the surveillance and control of Aedes vectors in key areas.

摘要： 目的掌握云南省登革热跨境输入病例的流行特征，为云南省开展登革热跨境输入防控提供指导。方法从中国疾病预防控制信息系统传染病报告信息管理系统中获取云南省登革热的输入病例信息，应用Excel 2016软件对数据进行整理和绘图，SPSS 19.0软件对数据进行统计分析处理，ArcGIS 10.5软件绘制登革热输入病例地理分布图。结果 2005－2019年云南省登革热境外输入病例4 660例，其中来源于东南亚的病例占境外输入病例总数的98.99%（4 613/4 660），缅甸输入病例占东南亚输入病例总数的86.06%（3 970/4 613）。缅甸输入病例中，输入到德宏傣族景颇族自治州的登革热病例数占缅甸输入病例总数的62.04%（2 463/3 970），输入病例高峰为10月，占总输入病例数的35.49%（1 409/3 970）；缅甸输入病例男性略多于女性，男女性别比为1.19∶1，以21～30岁年龄组人群最多，占比为27.71%（1 100/3 970），职业多集中于农民和商业服务人员，分别占病例总数的42.95%（1 705/3 970）和21.49%（853/3 970）。结论云南省边境地区的登革热输入风险较高，建议加强联防联控，有针对性地加大对重点人群登革热防控知识的宣传力度，以及加强重点地区登革热输入病例监测和媒介伊蚊监测与控制。
