Peak timing: effect of intra-EU mobility connections. (A) Delay of the A/H1N1 pandemic peak time in the scenario with no intra-EU air connections, with respect to the reference stochastic forecast output (SFO) set, for 22 European countries. (B) Map of Europe, showing for each country the fraction of traffic directed to and from non-European countries. Countries with small extra-European connections experienced the largest delay in the A/H1N1 pandemic peak time. The map was made exclusively for this manuscript and is not subject to copyright.
