基孔肯雅热是一种由伊蚊传播给人类的病毒性疾病。 1972年至1986年，在塞内加尔凯杜古，从廊林蚊子中分离出178株基孔肯雅病毒株，其中大部分是从伊蚊中分离出来的。 Furcifer-taylori（129 株），Ae。 uteocephalus（27 株）和 Ae。 dalzieli（12 株）。森林传播周期的特点是循环周期性，无声间隔持续约三年。塞内加尔很少有这种疾病流行的报道。最近一次发生在 1996 年，在卡夫林 (Kaffrine)，从伊蚊中分离出两种基孔肯雅病毒株。埃及伊蚊。对蚊子、野生脊椎动物和人类的病毒分离株进行回顾性分析，使我们能够描述塞内加尔基孔肯雅病毒的传播周期，并将其与黄热病病毒的传播周期进行比较。
Chikungunya fever is a viral disease transmitted to human beings by Aedes genus mosquitoes. From 1972 to 1986 in Kedougou, Senegal, 178 Chikungunya virus strains were isolated from gallery forest mosquitoes, with most of them isolated from Ae. furcifer-taylori (129 strains), Ae. luteocephalus (27 strains), and Ae. dalzieli (12 strains). The characteristics of the sylvatic transmission cycle are a circulation periodicity with silent intervals that last approximately three years. Few epidemics of this disease have been reported in Senegal. The most recent one occurred in 1996 in Kaffrine where two Chikungunya virus strains were isolated from Ae. aegypti. The retrospective analysis of viral isolates from mosquitoes, wild vertebrates, and humans allowed to us to characterize Chikungunya virus transmission cycles in Senegal and to compare them with those of yellow fever virus.
