Evolution mechanisms of Influenza A virus. (A) Antigenic Drift: Gradual accumulation of mutations in the genome of IAVs leads to emergence of new virus variants. (B) Antigenic Shift: The reassortment of genetic segments between two or more invading IAVs in a host cell can lead to emergence of an antigenically novel subtype.
