克里米亚-刚果出血热,是由克里米亚-刚果出血热病毒(CCHFV)引起的急性烈性传染病,以发热、出血为典型特征,病死率极高。CCHFV属于布尼亚病毒科内罗病毒属,是分节段单负链RNA虫媒(蜱传播)病毒。世界许多地区的动物和人群中有CCHFV抗体,表明病毒已不限于发病地区。本文综述了该病的分布特点和流行环节,特别指出硬蜱、鸟类迁徙及人类的活动(如旅游、动物贸易)等因素对CCHFV扩散传播的作用。
Crimean-Congo haemorrhagic fever, an acute and highly contagious disease caused by the Crimean-Congo haemorrhagic fever virus (CCHFV), is characterized by fever and bleeding and has a very high case fatality rate. CCHFV belongs to the genus Bunyavirus and belongs to the sub-single-negative chain RNA insect-borne (tick-borne) virus. There are CCHFV antibodies in animals and people in many parts of the world, indicating that the virus is not confined to the area of onset. This article reviews the distribution and epidemiology of the disease, with particular reference to the role of ticks and birds in migration and human activities such as tourism and animal trade on the spread of CCHFV.
