Resumen
Introduction: In Brazil, West Nile virus (WNV) was first detected, in 2018, in horses with neurological disease. Aim: We report the first case of WNV infection in a horse from Ceara state and the complete genome sequence of an isolate from Espirito Santo state. Both infections occurred in 2019. Methods: WNV was isolated from the tissues of a horse with neurological signs in Espirito Santo and sequenced by MiSeq. Results: Phylogenetic analysis revealed that the isolate belongs to lineage 1a, clustering with the NY99 strain, a strain that has not circulated in the USA since 2005. Conclusions: Our findings reinforce the hypothesis that WNV has been silently circulating in Brazil for many years.
