Longitudinal analysis of influenza A virus deletion-containing viral genomes reveals key determinants of co-evolutionary dynamics and interference
The substantial genetic diversity generated during influenza A virus replication facilitates both evasion of pre-existing host immunity and cross-species emergence. A major contributor to this diversi...
