Chikungunya, an arboviral disease transmitted by Aedes mosquitoes, has recently increased dramatically in incidence and geographic extent. Large outbreaks have affected islands of the Indian Ocean, India and other parts of South and Southeast Asia, Africa and most recently Italy. International travellers have disseminated new strains of the virus, some into regions from which chikungunya has hitherto been absent. In parallel, over the past 30 years international trade has resulted in the spread of A. albopictus from its original range in Asia, to all continents but Antarctica, thereby extending the geographic area over which transmission can occur.
基孔肯雅热是一种由伊蚊传播的虫媒病毒疾病，最近其发病率和地理范围急剧增加。大规模疫情已影响到印度洋岛屿、印度以及南亚和东南亚其他地区、非洲，最近还影响到意大利。国际旅行者传播了该病毒的新毒株，其中一些传入了此前从未出现过基孔肯雅热的地区。与此同时，在过去30年里，国际贸易导致白纹伊蚊从其在亚洲的原生范围扩散到除南极洲以外的所有大陆，从而扩大了可能发生传播的地理区域。
