Abstract excerpt
BACKGROUND: HA and NA are important surface proteins of influenza viruses. The purpose of this study was to explore the molecular evolution and amino acid mutations of HA and NA of H1N1, H3N2 and Influenza B Victoria lineage (B/Victoria) viruses in Qingyang from 2020 to 2023. METHODS: Through the China Influenza Surveillance Information System, the positive data of influenza etiology surveillance in Qingyang from...
