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…

I am an Italian blogger, active since 2005 with main focus on emerging infectious diseases such as avian influenza, SARS, antibiotics resistance, and many other global Health issues. Other fields of interest are: climate change, global warming, geological and biological sciences. My activity consists mainly in collection and analysis of news, public services updates, confronting sources and making decision about what are the 'signals' of an impending crisis (an outbreak, for example). When a signal is detected, I follow traces during the entire course of an event. I started in 2005 my blog ''A TIME'S MEMORY'', now with more than 40,000 posts and 3 millions of web interactions. Subsequently I added an Italian Language blog, then discontinued because of very low traffic and interest. I contributed for seven years to a public forum ( in the midst of the Ebola epidemic in West Africa in 2014, I left the site to continue alone my data tracking job.
