Disease spreading through human travel networks has been a topic of great interest in recent years, such as with swine in fl uenza or SARS pandemics. Most studies have proposed removing highly connected nodes (hubs) to control spreading. Here, we test alternative strategies using edge removal ( fl ight cancellation) for spreading over the airline network. Flight cancellation was more ef fi cient than shutting down whole airports: spreading took 81% longer if solely selected fl ights were removed, compared to a 52% reduction when entire airports were shutdown, affecting the same number of fl ights.
近年来，疾病通过人类旅行网络传播一直是备受关注的话题，比如猪流感或非典大流行。大多数研究都提议通过移除高度连接的节点（枢纽）来控制疾病传播。在此，我们测试了利用边移除（航班取消）来控制疾病在航空网络上传播的替代策略。航班取消比关闭整个机场更有效：如果只取消选定的航班，传播时间会延长81%，而当整个机场关闭时（影响相同数量的航班），传播时间减少了52%。
