This research article details the discovery and analysis of a novel triple-reassortant H3N3 avian influenza virus (AIV) in China. Researchers isolated the virus from a sick chicken, sequenced its complete genome, and performed phylogenetic analyses. The findings indicate the virus originated from reassortment events involving H3N8, H9N2, and H10N3 AIVs. While classified as low pathogenicity, several mutations raise concerns about potential increased virulence and transmission in mammals. The study highlights the need for continued surveillance of avian influenza viruses in poultry to prevent future outbreaks.
