摘要:

控制传染病传播对避免潜在的致命后果和减少不可预见的社会经济影响至关重要。2003年的严重急性呼吸系统综合症(SARS)就是有效控制的例子,SARS造成近千人死亡,航空公司和相关企业破产。在这篇文章中,我们研究的传染病传播的控制策略的有效性的基础上删除连接在现实世界中的航空公司网络与相关的经济和社会成本考虑到通过定义适当的量化措施。我们发现了令人惊讶的结果,即删除不太繁忙的连接可以比删除更流行的连接更有效地阻止疾病的传播。由于断开不太受欢迎的路线往往会产生更少的社会经济成本,我们的研究结果表明,有可能以疫情控制效率换取重要枢纽连通性的最小减少。特别是,我们展示了各种本地流行病控制策略的性能,并展示了我们的方法如何通过传播控制特性来预测其成本效益。

英文摘要:

The control of epidemic spreading is essential to avoid potential fatal consequences and also, to lessen unforeseen socio-economic impact. The need for effective control is exemplified during the severe acute respiratory syndrome (SARS) in 2003, which has inflicted near to a thousand deaths as well as bankruptcies of airlines and related businesses. In this article, we examine the efficacy of control strategies on the propagation of infectious diseases based on removing connections within real world airline network with the associated economic and social costs taken into account through defining appropriate quantitative measures. We uncover the surprising results that removing less busy connections can be far more effective in hindering the spread of the disease than removing the more popular connections. Since disconnecting the less popular routes tend to incur less socio-economic cost, our finding suggests the possibility of trading minimal reduction in connectivity of an important hub with efficiencies in epidemic control. In particular, we demonstrate the performance of various local epidemic control strategies, and show how our approach can predict their cost effectiveness through the spreading control characteristics.
