A yellow fever outbreak occurred in 1966 in Arba-Minch District, east of Abaya Lake, in Ethiopia. The present study was undertaken to assess the southern limits of that epidemic and to contribute to the inventory of arboviruses and potential vectors in that area. In the highlands 90 sera were collected, in the lowlands 140. With regard to Group B the sera reacted only with yellow fever, Wesselsbron and Spondweni antigens. In the highlands 17.8%, in the lowlands 22.2%, were positive for group B. In two sera only the titers against yellow fever were high. The absence of reactivity to West Nile virus was striking. A wide variety of Culicidae was present and differentiated. Potential or proven vectors were collected. At the time of the survey yellow fever was not active in the region. Because of an only partly immune human population, and of the presence of non-immune monkeys and some potential vectors, the area should, however, be considered to be receptive.
1966年，埃塞俄比亚阿巴亚湖以东的阿尔巴明奇地区爆发了黄热病疫情。本研究旨在评估该疫情的南部边界，并为该地区虫媒病毒和潜在病媒的清查工作提供资料。在高地采集了90份血清，在低地采集了140份。关于B组，血清仅与黄热病、韦塞尔斯布朗病和斯庞德温尼病抗原发生反应。在高地，B组阳性率为17.8%，在低地为22.2%。仅两份血清中针对黄热病的滴度较高。对西尼罗河病毒无反应性十分显著。采集到了种类繁多的蚊科昆虫并进行了鉴别。收集到了潜在或已证实的病媒。在调查时，该地区黄热病并未活跃传播。然而，由于当地人群仅有部分免疫，且存在未免疫的猴子和一些潜在病媒，该地区应被视为易感地区。
