摘要: In 2008, dengue virus serotype 4 (DENV-4) emerged in northeastern Peru, causing a large outbreak and displacing DENV-3, which had predominated for the previous 6 years. Phylogenetic analysis of 2008 2009 isolates support their inclusion into DENV-4 genotype II, forming lineage distinct from strains that previously circulated region.
