基孔肯雅热(chikungunya fever)是由基孔肯雅病毒(chikungunya virus)引起的一种蚊媒传染病，感染率高，可引起持续的关节症状。近几年来，基孔肯雅热暴发次数增加，流行范围不断扩大，全球范围内每年可导致100万人感染。同时，基孔肯雅病毒中某些基因突变使其可有效通过白纹伊蚊传播，不仅对热带和亚热带地区，还对白纹伊蚊广泛存在的温带地区的民众构成了潜在威胁.

Chikungunya fever is a mosquito-borne infectious disease caused by chikungunya virus, with high infection rate and persistent joint pain. In recent years, outbreak of chikungunya fever increased with expanding epidemic scope, leading to one million infected cases each year worldwide. Meanwhile, some chikungunya virus genotypes have gained some mutations which result in more effectively spread by Aedes albopictus. So it poses a potential threat to the residents not only in tropical and subtropical regions, but also in temperate regions with Aedes albopictus.
