摘　　要：目的应用可视化软件制作流感疫情传播关系图,分析传播特征。方法应用Excel建立传播关系数据库,然后将数据导入可视化软件Gephi,创建传播关系图。结果通过传播网络分析,将病例间和病例接触者间的关系进行了可视化展示,找到了此次疫情的首发病例和传播关键病例,为防控措施的应用提供了依据。结论应用可视化软件进行流感疫情传播网络分析,可准确、直观的反映传播特征。Objective To draw influenza transmission graphs using visualization software and analyze transmis- sion characteristics. Methods A transmission database was established using Excel, and then data were im- ported to visualization software Gephi to create a transmission graph. Results Through transmission network analysis, relationships among patients and patient contact persons were displayed in a visible manner so that the first case and key cases of the outbreak were identified, providing a basis for application of prevention and control measures. Conclusion Analysis of the influenza transmission network using the visualization software can accurately and directly reflect the transmission characteristics of influenza outbreaks.
