Key result
Two novel duck reovirus (NDRV) strains were isolated from ducklings with spleen necrosis disease in Henan province, China, with phylogenetic analysis showing Chinese NDRVs have evolved into two distinct clades.

Emerging NDRV cases in Chinese ducklings signal need for surveillance; leaves open questions on transmission, vaccines, and control.
The study identifies two novel duck reovirus strains in China, revealing that Chinese NDRVs have evolved into two distinct clades since late 2017.
Peng et al. (2023) studied Duck spleen necrosis disease (n=15). Novel Duck reovirus (NDRV) infection was evaluated on Viral identification and phylogenetic analysis of sigma C genes. Two novel duck reovirus (NDRV) strains were isolated from ducklings with spleen necrosis disease in Henan province, China, with phylogenetic analysis showing Chinese NDRVs have evolved into two distinct clades.
