Abstract
After a sharp decrease of influenza A(H7N9) virus in China in 2018, highly pathogenic H7N9 viruses re-emerged in 2019. These H7N9 variants exhibited a new predominant subclade and had been cocirculating at a low level in eastern and northeastern China. Several immune escape mutations and antigenic drift were observed in H7N9 variants.
Keywords: China; H7N9 viruses; HPAI; antigenic drift; evolution; high pathogenicity; highly pathogenic avian influenza; influenza; influenza virus; low pathogenicity; viruses.
