We now have a deeper understanding of the role of air travel in the spread of disease. Studies published at the end of last year by Dirk Brockmann, now at Humboldt University and the Robert Koch-Institute in Berlin, and Dirk Helbing at ETH Zurich, led to a new mathematical theory for understanding the spread of epidemics. This focuses on travel hubs and links so that if the flow of passengers from point A to point B is large, the effective distance is small and vice versa.
