航空网络在传染病区域性扩散中扮演着重要角色,研究航空网络结构及其对传染病区域扩散的影响对重大传染病应急防控具有重要的现实意义。本文研究了中国及全球航空网络的拓扑结构,并以中国航空网络为载体,模拟了类流感疾病在网络上的传播过程。结果显示,航空网络加快了疫情的区域性扩散,在不施加控制的情况下,很短的时间内,疫情就可以蔓延至整个网络。
Aviation network plays an important role in the regional spread of infectious diseases. It is of great practical significance to study the structure of aviation network and its impact on the spread of infectious diseases for emergency prevention and control of major infectious diseases. This paper studies the topological structure of China’s and the world’s aviation networks and uses China’s aviation network as a carrier to simulate the spread of influenza-like illness on the Internet. The results showed that the aviation network accelerated the regional spread of the epidemic and, without any control, the outbreak could spread to the entire network within a very short period of time.
