摘要

2014年，一种类似于登革热的传染病———基孔肯雅热席卷了中南美洲，其病原体为基孔肯雅病毒，隶属于披膜病毒科甲病毒属的单股正链RN A病毒，传播媒介主要是伊蚊属，尤其是白纹伊蚊和埃及伊蚊。基孔肯雅热的临床症状与登革热十分相似，临床上需要鉴别诊断。2010年该疾病在我国广东曾小规模流行，其对人民健康造成的危害以及所带来的经济负担不亚于登革热，应高度重视，遏制其蔓延。%Numerous Chikungunya outbreaks have occurred throughout Central and South America in 201 4.Around a million of local residents suffered.Chikungunya virus is a member of Genus Alphavirus,Family Togaviridae.The genome is a positive-sense single-stranded RNA.Genus Aedes mosquitoes are main vectors,especially Aedes albopictus and Aedes aegypti.The disease caused by the virus shows some similarities with Dengue fever in clinical manifestations.We need to pay attention to diagnosis of those two diseases.A small-scale epidemic of Chikungunya occurred struck in Guangdong Province in 201 0 with the degree of health threat.It's in great need of controlling the spread of Chikungunya virus,for its economic burden is no less than that of Dengue virus.
