Vaccination in all countries, 30% of population are immunized (R0, max = 1.5 and GI = 2). Dynamics of the pandemic starting from Mexico City, in late March 2009, with vaccine available in all countries 6 months after the pandemic onset. Thirty percent of worldwide population are vaccinated at a daily rate of 1%. The upper panel represents average daily incidences for Northern (green), Southern (blue), tropical (black) and all (red) cities. Plain lines correspond to means and dashed lines (for the global curve only) to .05 and .95 pointwise quantiles calculated on 500 simulation runs. The lower panel illustrates the spread of the virus through the 52 cities of the network; the predicted probability of influenza activity is represented for each city (from 0 (white) to 1 (black)).
