Figure 4
Radial plots of countries with HA and NA reported between April and December 2009 show population genetic indexes from countries that reported the higher number of influenza sequences paired against all those with A H1N1. Yellow and blue areas correspond to gene flow (Nm × 102) for HA and NA respectively; triangles correspond to FST values, full for HA and empty for NA; circles correspond to GST values, full for HA and empty for NA. In order to facilitate viewing all values 3 or above are seen as 3.
