Detection of Saint Louis encephalitis virus in two Brazilian states.

We describe the circulation of Saint Louis encephalitis virus (SLEV) in two Brazilian States during outbreaks of Dengue and Zika viruses. We detected the virus in patients from Araraquara, State of Sao Paulo, and in patients and mosquitoes Culex quinquefasciatus from Sinop, State of Mato Grosso. Phylogenetic analysis grouped our samples within genotype V, which are closely related to other strains. This genotype was previously detected in other parts of the country and seems to have established circulation in Brazil. This article is protected by copyright. All rights reserved.
