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.
2017年4月，6名从塞舌尔返回的以色列旅行者被诊断感染登革热病毒。系统发育分析在所有测序样本中鉴定出属于登革热病毒2型全球基因型的相同序列，从而为塞舌尔可能发生的登革热2型疫情提供了证据。本报告进一步证明了旅行者作为虫媒病毒感染哨兵的作用，特别是在诊断能力有限的国家。
