Senecavirus A (SVA) the only member of the Senecavirus genus within the Picornaviridae family, is an emerging pathogen causing swine idiopathic vesicular disease and epidemic transient neonatal losses. Here, SVA strain (CH-HNKZ-2017) was isolated from a swine farm exhibiting vesicular disease in Henan Province of Central China. A phylogenetic analysis based on complete genome sequence indicated that CH-HNKZ-2017 was closely related to US-15-40381IA, indica- ting that a new SVA isolate had emerged in China.
A组赛内卡病毒（SVA）是小核糖核酸病毒科赛内卡病毒属的唯一成员，是一种新出现的病原体，可引起猪特发性水疱病和流行性短暂性新生儿死亡。在此，从中国中部河南省一个出现水疱病的养猪场分离出SVA毒株（CH-HNKZ-2017）。基于全基因组序列的系统发育分析表明，CH-HNKZ-2017与美国-15-40381IA密切相关，这表明中国出现了一种新的SVA分离株。
