Abstract
AbstractSwine influenza virus (SwIV) surveillance in Hanoi, Vietnam from 2013–2019 found gene pool enrichment from imported swine from Asia and North America. Long-term maintenance, persistence and reassortment of SwIV lineages was observed. Co-circulation of H1-δ1a viruses with other SwIV genotypes raises concern due to its zoonotic potential.
