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性人畜共患病，在许多非洲国家导致人类和动物的严重发病率和死亡率。在尼日利亚卡杜纳州杰马阿地方政府区的吉丹-瓦亚森林保护区周围饲养的绵羊群体中进行了一项横断面研究，使用商业竞争性酶联免疫吸附试验确定是否存在感染裂谷热病毒 (RVFV) 的血清学证据。在 200 只采样的绵羊中，有 9 只（4.5%；95%置信区间 2.23-8.33）对 RVFV 抗体呈阳性。抗体的检测表明绵羊中有隐性传播，可能表明存在亚临床感染。
