自2007年意大利首次暴发基孔肯雅热以来，欧洲一直面临着虫媒病毒性疾病在当地传播的增加。登革热病毒（DENV）和基孔肯雅病毒（CHIKV）都是由存在于20个欧洲国家的白纹伊蚊传播的。欧洲出现的CHIKV主要与东非-中非-南非（ECSA）基因型有关，最近在2014年法国南部发生的11例CHIKV病例就是例证。尽管有数百名旅行者从美洲返回，其中亚洲基千伏病毒基因型造成了100多万例病例，但在欧洲没有报告与亚洲基因型相关的本地传播。因此，根据蚊子种群、病毒基因型和温度等环境因素，传播模式可能存在显著差异。
Since the first outbreak of chikungunya in Italy in 2007, Europe has been facing an increase in local transmission of arboviral diseases. Dengue virus (DENV) and chikungunya virus (CHIKV) are both transmitted by the mosquito Aedes albopictus present in 20 European countries. CHIKV emergence in Europe was mainly associated with the East-Central-South African (ECSA) genotype, recently exemplified by the 11 CHIKV cases in southern France in 2014. Despite hundreds of travelers returning from the Americas where the Asian CHIKV genotype was responsible for more than one million cases, no autochthonous transmission associated with the Asian genotype was reported in Europe. Thus the pattern of transmission can be significantly different depending on the mosquito population, the virus genotype and environmental factors such as temperature.
