Figure 3

Radial plots of countries with HA and NA reported along the first four months (April-July, 2009) of the pandemic show population genetic indexes from countries that reported the higher number of influenza sequences paired against all those countries with A H1N1. Yellow and blue areas correspond to gene flow (Nm × 10²) for HA and NA respectively; triangles correspond to F_ST values, full for HA and empty for NA; circles correspond to G_ST values, full for HA and empty for NA. In order to facilitate viewing all values above 3 they are seen as 3.
