From: Monitoring the antigenic evolution of human influenza A viruses to understand how and when viruses escape from existing immunity

Figure 3

Partial patterns of the evolutionary dynamics of regional human influenza A/H3N2 viruses. Left and right patterns were obtained by analyzing the viruses globally and those isolated in E-SE Asia, respectively. The upper panel (A) reveals that the amino acid transitions occur in E-SE Asia beforehand. The bottom panel (B) reveals that the amino acid substitutions become fixated in E-SE Asia.
