Emergence of Influenza A(H7N4) Virus, Cambodia.
Vijaykrishna D, Deng YM, Grau ML, Kay M, Suttie A, Horwood PF, Kalpravidh W, Claes F, Osbjer K, Dussart P, Barr IG, Karlsson EA.
Abstract
Active surveillance in high-risk sites in Cambodia has identified multiple low-pathogenicity influenza A(H7) viruses, mainly in ducks. None fall within the A/Anhui/1/2013(H7N9) lineage; however, some A(H7) viruses from 2018 show temporal and phylogenetic similarity to the H7N4 virus that caused a nonfatal infection in Jiangsu Province, China, in December 2017.
KEYWORDS:
Cambodia; H7N4; influenza surveillance; influenza virus; live poultry markets; phylogenetics; subtype A/H7N4; viruses; whole genome sequencing; zoonotic infection
