Recent Human Influenza A/H3N2 Virus Evolution Driven by Novel Selection Factors in Addition to Antigenic Drift
10 Sept 2009
Abstract excerpt
BACKGROUND: Examination of the evolutionary dynamics of complete influenza viral genomes reveals that other processes, in conjunction with antigenic drift, play important roles in viral evolution and selection, but there is little biological evidence to support these genomic data. Previous work demonstrated that after the A/Fujian/411/2002-like H3N2 influenza A epidemic during 2003-2004, a preexisting nondominant...
