Serological surveys undertaken to define the geographic limits of the 1970 rural yellow fever epidemic in Okwoga District, Nigeria, indicated that surrounding areas of Benue Plateau State and East Central State were not involved. However, the surveys uncovered a separate focus of unrecognized, recent epidemic yellow fever in Mbawsi, in southern East Central State. The highest proportions of yellow-fever-immune sera outside the Okwoga and Mbawsi foci were found in zones of Guinea savannah in the Benue River basin.
为确定1970年尼日利亚奥克沃加地区农村黄热病疫情的地理范围而进行的血清学调查表明，贝努埃高原州和东中部州的周边地区未受波及。然而，这些调查在东中部州南部的姆巴西发现了一个单独的、未被识别的近期黄热病流行疫源地。在奥克沃加和姆巴西疫源地之外，黄热病免疫血清比例最高的地区是贝努埃河流域的几内亚草原地带。
