Abstract
After an outbreak of Rift Valley fever in Southern Mauritania in 1987, entomologic studies were conducted in a bordering region in Sénégal from 1991 to 1996 to identify the sylvatic vectors of Rift Valley fever virus. The virus was isolated from the floodwater mosquitoes Aedes vexans and Ae. ochraceus. In 1974 and 1983, the virus had been isolated from Ae. dalzieli. Although these vectors differ from the main vectors in East and South Africa, they use the same type of breeding sites and also feed on cattle and sheep. Although enzootic vectors have now been identified in West Africa, the factors causing outbreaks remain unclear.
摘要
1987年毛里塔尼亚南部爆发裂谷热疫情后，1991年至1996年在塞内加尔的一个毗邻地区开展了昆虫学研究，以确定裂谷热病毒的野生宿主。该病毒从洪水蚊种骚扰伊蚊和 Ochraceus伊蚊中分离出来。1974年和1983年，该病毒曾从达尔齐埃伊蚊中分离出来。尽管这些宿主与东非和南非的主要宿主不同，但它们利用相同类型的繁殖地，也以牛和羊为食。虽然现已在西非确定了地方性宿主，但疫情爆发的原因仍不清楚。
