Wolfe In PLoS Medicine, volume 3, issue 11, doi:10.1371/journal.pmed.0030502: Figure 1 from this correspondence was transposed with Figure 1 from the related correspondence by Viboud and colleagues (“Air Travel and the Spread of Infl uenza: Important Caveats” doi:10.1371/journal.pmed.0030503). The legend published with Figure 1 (“Infl uence of United States Airline Volume on Infl uenza Spread and the Timing of Yearly Transmission over 30 Infl uenza Seasons”) is correct. However, the fi gure itself should have appeared as shown below.
