Evolution and Antigenic Differentiation of Avian Influenza A(H7N9) Virus, China

Emerg Infect Dis. 2024 Apr 19;30(6). doi: 10.3201/eid3006.230530. Online ahead of print.ABSTRACTWe characterized the evolution and molecular characteristics of avian influenza A(H7N9) viruses isolated in China during 2021-2023. We systematically analyzed the 10-year evolution of the hemagglutinin gene to determine the evolutionary branch. Our results showed recent antigenic drift, providing crucial clues for updating the H7N9 vaccine and disease prevention and control.PMID:38640498 | DOI:10.3201/eid3006.230530
