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 Cote d'Ivoire. Phylogenetic analysis of the envelope gene showed that 2 genetically related virus isolates belonged to dengue virus type 3 genotype III.
旅行者可能会将疾病流行地区的病毒带入非疾病流行地区。3 名返回日本的旅行者的血清学和病毒学检测均确认感染了登革热病毒:2 人来自坦桑尼亚,1 人来自科特迪瓦。包膜基因的系统进化分析显示,2 株具有遗传相关性的病毒分离株属于登革热病毒 3 型基因型 III。
