RESUMO
In 2015 and 2016, Senecavirus A (SVA) emerged as an infectious disease in Brazil, China and the United States (US). In a Colombian commercial swine farm, vesicles on the snout and coronary bands were reported and tested negative for foot-and-mouth disease virus (FMDv), but positive for SVA. The whole-genome phylogenetic analysis indicates the Colombian strain clusters with the strains from the United States, not with the recent SVA strains from Brazil.

Numerous, ongoing outbreaks in Brazilian swine herds have been characterized by vesicular lesions in sows and acute losses of neonatal piglets. The complete genome of Seneca Valley virus (SVV) was identified in vesicular fluid and sera of sows, providing evidence of association between SVV and vesicular disease and viraemia in affected animals.
