Computer Modeling: Why Shutting Airports Is Not the Best Way to Halt a Global Flu Pandemic

In a deadly flu outbreak, shutting airports should reduce the spread of the disease. But networks scientists have discovered a better approach that’s just as effective. Jose Marcelino and Marcus Kaiser at Newcastle University in the UK, provide an answer. They say a better approach is to cut specific flights between airports because it can achieve the same reduction in the spread of the disease with far less drastic action. They found that shutting entire airports only had a significant effect on spreading if it reduced travel by 95 per cent. By contrast, they could achieve the same effect by removing just 18 per cent of flights between cities ranked by a network measure called edge betweenness.
