In 2019, flocks of Muscovy ducks presented with clinical signs typical of MDPV infection. The MDPV GD201911 strain was isolated by inoculating samples from positive birds into Muscovy duck embryos. Challenge with the isolate GD201911 caused typical MDPV disease symptoms and resulted in 25%–40% mortality, depending on the challenge dose, indicating the high pathogenicity of GD201911 for Muscovy ducks. Genome sequencing and phylogenetic analysis demonstrated that GD201911 clustered with recombinant MDPV strains, indicating that recombinant MDPV is circulating in China. Epidemiological monitoring should be performed continuously to assist with decision making for disease control.
