Abstract
Introduction: In Brazil, West Nile virus (WNV) was first detected in 2018 from horses with neurological disease.
Aim: Here we present the first reported case in Cear? state and complete genome sequence from an isolated in Esp?rito Santo state from 2019.
Methods: The virus was isolated from a horse that died with neurological signs in Esp?rito Santo and was sequenced by MiSeq.
Results: Phylogenetic analysis reveals that this isolate belongs to lineage 1a, clustering with NY99 strain, that disappeared from the USA since 2005.
Conclusions: Our findings reinforce the hypothesis that WNV has been silently circulating in Brazil for many years.
