Abstract excerpt
Subtype H9N2 of the avian influenza virus (AIV) poses a growing threat to the poultry industry and public health. However, since 2014, there has been no systematic study of its genetic evolution, genotype, spatial dynamics, and pathogenicity in China. Therefore, we performed a large-scale sequence analysis of the genome of Chinese H9N2 viruses from 2014 to 2025 using public databases and laboratory isolates. We...
