Dear Editor,

Since the first outbreak in Brazil in 2015, Seneca Valley virus (SVV) associated with porcine idiopathic vesicular disease, has shown increasing geographic distribution. Cases of SVV have been reported from several countries including the United States (US), Colombia, Thailand, Canada, and China (Pasma et al.2008; Zhang et al.2015; Sun et al.2017; Wu et al.2017; Liu et al.2018; Saeng-Chuto et al.2018). SVV was first identified in the US in 2002 and is the only member of the genus Senecavirus in the family Picornaviridae (Hales et al.2008; Leme et al.2017). The SVV genome contains a large open reading frame (ORF) encoding a polyprotein, which is cleaved into various mature viral proteins including the leader protein (L), structural proteins (VP1, VP2, VP3, and VP4), and non-structural proteins (2A, 2B, 2C, 3A, 3B, 3C, and 3D) (Hales et al.2008). Structural proteins bind to their receptor, anthrax toxin receptor 1, to mediate viral invasion and stimulate specific immunity...
