Figure 4

Ratios between total number of avian influenza A(H5N1) HA sequences and the total number of human cases of influenza A(H5N1) (data between 2003 and 2011 as shown in Figure 3). This analysis revealed significant differences between countries. The ratio difference between Nigeria and Azerbaijan represent a 285 fold difference. Statistical analysis was performed by means of Kolmogorov-Smirnov test for goodness-of-fit to power law distributions using lower (P = 0.0025), middle (P = 0.0011), and upper (P = 0.0165) quartiles.
