Geese play an important role in agricultural economics, with China producing the vast majority of goose meat consumed worldwide annually. The variations in the avian viruses and co‐infections result in substantial economic losses to the goose industry in China. To understand the evolutionary characteristics and co‐infections of viruses, a broad epidemiological investigation of epizootic viruses of goose was carried out in nine provinces of China during 2018–2021. Here, the results indicated that, among the 1970 clinical samples, 50.81% (1001/1970) were positive for goose astrovirus (GAstV), 18.22% (359/1970) for avian orthoreovirus, 12.74% (251/1970) for goose parvovirus, 11.02% (217/1970) for H9N2 subtype avian influenza virus, 4.01% (79/1970) for Newcastle disease virus, and 2.08% (41/1970) for fowl adenovirus. Among the six viruses, co‐infections comprised a large proportion (66.37%) in the field, of which the dual infection was more common. Additionally, phylogenetic analysis of GAstVs indicated that Chinese GAstVs had formed two distinct groups, that is, GAstV‐1 and GAstV‐2. GAstV‐2 sub‐genotype II‐c had arisen as the dominant genotype in the whole country. Notably, all the H9N2‐AIV isolated strains harboured the mammalian adaptation markers I155T, H183N, and Q226L (H3 numbering) in the HA gene, which promotes preferential binding to human‐like α2‐6‐linked sialic acid receptors. And beyond that, we determined that the goose‐origin Muscovy Duck Reovirus isolates, showing 51.7%–96% similarities to that of other waterfowl‐origin orthoreovirus isolates in sequence homology analysis of the representative part of σC, are a new variant of waterfowl‐origin orthoreovirus. These data provide valuable information about the prevalence of infectious diseases in geese on mainland China. [ABSTRACT FROM AUTHOR]
