Data
Whenever an infectious disease poses the risk of spreading into a global pandemic, air transportation plays a key role. Modern air traffic connects every corner of our globe. In doing so, it also enables regionally confined outbreaks of infectious diseases to “jump” across country borders at an unprecedented rate.
Therefore, the core of the computational model is the worldwide air transporation network (WAN). This network has 3893 nodes (airports) that are connected by 51476 directed links (flight routes). Each link is weighted by the traffic flux between nodes, i.e. the average number of passengers that travel each route per day.
The WAN has been analyzed in many publications and used in a variety of computational models for the spread of infectious diseases.
Properties of the worldwide air transportation network
The WAN exhibits strong intrinsic structural heterogeneity – some airports are tiny, while others are huge international hubs. These distinctions can be observed by examining the wide-range of magnitudes of various properties of the WAN – a clear sign of network heterogeneity, summarized below.
