Euro Surveill. 2017 Jun 29;22(26):30563. doi: 10.2807/1560-7917.ES.2017.22.26.30563.

Abstract

Dengue virus infection was diagnosed in six Israeli travellers returning from the Seychelles in April 2017. Phylogenetic analysis identified identical sequences belonging to the Cosmopolitan genotype of dengue virus type 2 in all samples sequenced, thus providing evidence for a probable dengue type 2 outbreak in the Seychelles. This report further demonstrates the role of travellers as sentinels for arboviral infections, especially in countries with limited diagnostic capabilities.

Keywords: Dengue type 2; Israel; The Seychelles; Travelers; cosmopolitan lineage.
