An outbreak of dengue-like disease was observed in Luanda, Angola, at the end of 1970 and beginning of 1971. Chikungunya virus was isolated from the blood of a patient with typical symptoms of dengue and from a pool of Aedes aegypti mosquitos. A survey for antibodies to arboviruses in the sera of persons living in Luanda showed that the Chikungunya virus was indeed responsible for the outbreak. The fact that this outbreak immediately preceded and continued concurrently with a yellow fever epidemic in Luanda shows that two arboviruses from different antigenic groups may circulate simultaneously in the same ecological area.
1970年末至1971年初,安哥拉罗安达出现了登革热样疾病的暴发。从一名有典型登革热症状的患者血液以及一批埃及伊蚊中分离出了基孔肯雅病毒。对罗安达居民血清中虫媒病毒抗体的一项调查显示,基孔肯雅病毒确实是此次暴发的病因。此次暴发紧接罗安达的黄热病疫情之前发生并与之同时持续,这一事实表明,来自不同抗原组的两种虫媒病毒可能在同一生态区域同时传播。
