Importation of Dengue Virus Type 3 to Japan from Tanzania and Côte d’Ivoire

Abstract

Travelers can introduce viruses from disease-endemic to non–disease-endemic areas. Serologic and virologic tests confirmed dengue virus infections in 3 travelers returning to Japan: 2 from Tanzania and 1 from Côte d’Ivoire. Phylogenetic analysis of the envelope gene showed that 2 genetically related virus isolates belonged to dengue virus type 3 genotype III.
