Abstract
Dengue virus has recently reemerged in the southern Indian Ocean islands, causing outbreaks in Reunion Island and the Seychelles. In the present study, we determined the complete genome sequences of closely related clinical isolates of dengue virus type 2 circulating in the Seychelles in 2016 and Reunion Island in 2018.
Highlights
Like many tropical regions in which competent mosquito vectors are present, the islands of the southwestern Indian Ocean have experienced a renewal of human pathogenic arbovirus emergence (1, 2)
Phylogenetic analysis of the two genomes with full sequences available for representative DENV strains (10) positioned the RUJul and RU16417 strains within dengue virus type 2 (DENV-2) Cosmopolitan genotype lineage I (Fig. 1), confirming previous results (11)
The assembled genomes were deposited in GenBank under accession numbers MN272404 (RUJul) and MN272405 (RU16417)
Summary
Like many tropical regions in which competent mosquito vectors are present, the islands of the southwestern Indian Ocean have experienced a renewal of human pathogenic arbovirus emergence (1, 2). Microbiology Resource Announcement identity with the genomic sequence of a DENV-2 strain from Thailand (GenBank accession number KX380828).
