The phylogenetic tree is based on a 1,032 nucleotide alignment of E-protein sequences of all detected WNV strains and selected global WNV strains (A) or on an alignment of the entire open reading frame (ORF) of WNV M6848-NA-2020 and M6646-NA-2020 and selected global WNV strains (B). Branch support is given for each branch. Virus sequences identified in this study are shown in red. Reference sequences are marked with their accession number in grey and the two-letter code of their countries of origin. AU, Australia; CY, Cyprus; CZ, Czechia; ES, Spain; GR, Greece; IN, India; MG, Madagascar; RU, Russia; UG, Uganda; US, United States of America; ZA, South Africa. The phylogenies are rooted to a WNV lineage 4 strain from Russia (AY277251).
