Abstract
The complete nucleotide sequences of two West Nile virus (WNV) strains isolated in Argentina were determined. Phylogenetic trees were constructed from the aligned nucleic acid sequences of these two strains along with other previously published complete WNV genome sequences. Phylogenetic data showed that both strains belonged to clade 1a of lineage 1 and clustered in a subclade with American strains isolated during 1999-2002. These results suggest two independent routes of introduction of WNV in Argentina and that the virus could have been circulating in Argentina for some time before being isolated.
