“…Since its original discovery in the St Louis region of North America, SLEV has been associated with more than 50 outbreaks or epidemics throughout North America (Kopp et al, 2013). Additional epidemics have been recorded in South America since 1960, mainly in Argentina and Brazil (Tauro et al, 2012;Pauvolid-Corrêa et al, 2010;Díaz et al, 2005) and other countries (Burgueño et al, 2013), including the recent isolation of genotype V, sub genotype A of SLEV from a person in Peru (Felices et al, 2014). Also, SLEV infections have been reported in humans and horses in the Caribbean (Pupo et al, 2006;Thompson et al, 2012).…”
