Chikungunya fever is a viral disease transmitted to human beings by Aedes genus mosquitoes. From 1972 to 1986 in Kédougou, 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.
基孔肯雅热是一种由伊蚊属蚊子传播给人类的病毒性疾病。1972年至1986年期间，在塞内加尔的凯杜古，从森林廊道蚊子中分离出178株基孔肯雅病毒毒株，其中大部分分离自泰勒氏叉尾蚊（129株）、黄头伊蚊（27株）和达尔齐尔伊蚊（12株）。丛林传播周期的特点是存在持续约三年的无症状间隔的循环周期。塞内加尔报告的该疾病疫情较少。最近一次发生在1996年的卡菲林，从埃及伊蚊中分离出两株基孔肯雅病毒毒株。对来自蚊子、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，并将其与黄热病毒的传播周期进行比较。
