For a description of the Monte Carlo procedure used in the work to estimate the seasonal transmission potential and the results obtained for the projections of the winter activity peaks in the Northern hemisphere, have a look at this post.
The map below shows the 12 countries infected by travelers from Mexico used in the Monte Carlo likelihood analysis to estimate the H1N1 transmission potential. The color code of the arrows from red to yellow indicates the time ordering of the epidemic invasion.
