Rift Valley fever is an arboviral zoonoses causing severe morbidity and mortality among humans and animals in many African countries. A cross-sectional study in populations of sheep reared around the Gidan-Waya Forest Reserve located in Jema’a LGA of Kaduna State, Nigeria to determine the serological evidence of exposure to Rift Valley fever virus (RVFV) using a commercial competitive enzyme-linked immunosorbent assay. Of the 200 sheep sampled, 9 (4.5%; 95 CI 2.23–8.33) were positive for antibodies to the RVFV. The detection of antibodies suggests a covert circulation among the sheep and may be indicative of a subclinical infection.

裂谷热是一种虫媒病毒，在许多非洲国家引起人类和动物的严重发病和死亡。对位于尼日利亚卡杜纳州 Jema'a LGA 的 Gidan-Waya 森林保护区周围饲养的绵羊种群进行横断面研究，以确定使用商业竞争性酶联酶联免疫技术暴露于裂谷热病毒 (RVFV) 的血清学证据免疫吸附试验。在采样的 200 只羊中，有 9 只（4.5%；95 CI 2.23–8.33）的 RVFV 抗体呈阳性。抗体检测表明绵羊之间存在隐蔽循环，可能表明存在亚临床感染。
