Abstract

Novel highly pathogenic avian influenza (HPAI) H7N9 viruses of the fifth epidemic wave infect humans and poultry. Recently, HPAI H7N9 viruses have evolved into different subtypes and genotypes, exhibited heightened virulence in mammals, and extended their host range, thereby posing a potential threat to public health and the poultry industry.
