Key result
Genomic analysis of virulent goose astrovirus isolates reveals G-I classification and mutations suggesting vertical transmission.
Why the study?
Since early 2020, continuous emergence of fatal goose astrovirus infections characterized by articular and visceral gout was reported in China, posing threats to public health and the poultry industry.
Population
Two outbreaks of gout disease in two goose farms and goose hatcheries in central China
Design
Outbreak investigation and genomic characterization study

Emerging GAstV gout outbreaks in geese warrant enhanced surveillance; leaves open questions on transmission dynamics and control measures.
Observational
Yes
The study identifies and characterizes emerging virulent goose astrovirus strains in central China, highlighting their genetic evolution and potential vertical transmission.
Zhang et al. (2021) conducted an observational in Goose astrovirus (GAstV) infection. Goose astrovirus (GAstV) infection was evaluated on Genomic characterization and phylogenetic analysis of GAstV isolates. Genomic analysis of three virulent goose astrovirus isolates from central China revealed they belong to the G-I group and possess several amino acid mutations suggesting vertical transmission.
