Phylogenetic trees were constructed with MEGA v5.0 software using neighbor-joining algorithm with Maximum Composite Likelihood parameter model based on nucleic acid sequences of a 875 bp long region of the non-structural gene (NS5) (a) and a 865 bp sequence of the envelope glycoprotein gene (E) (b). The Hungarian WNV strain (WNV/189Uu/2011, KJ592829 and KJ592830) detected in this study was marked in bold face. Number of bootstrap replications was 1,000, and the analysis was performed rooted using Usutu virus as outgroup
