West Nile virus (WNV) is an emerging arbovirus which affects humans and horses. A cross sectional study was carried out on 106 local horses in Kaduna and 78 domestic chickens in Federal Capital Territory. A total of 184 sera were screened for West Nile virus anti Pr‑E antibodies using ID Screen® West Nile competitive enzyme linked immunosorbent assay. For the horses, an overall prevalence of 92.45% was recorded while domestic chickens had a preponderance of 7.69%. From our study, there was a statistical significant difference between the occurrences of WNV in stallions than mares with p < 0.05. Comparing the occurrence of West Nile virus between species, horses were more likely to be infected by West Nile virus than domestic chickens (OR 147). This is the first seroprevalence study investigating West Nile virus infection in domestic chickens in Nigeria. The presence of the antibodies indicates the widespread circulation and the potential risk of infection in humans and animals. In order to understand the epidemiology of West Nile virus infection in Nigeria, there is need for surveillance to be implemented in human and animal sectors.
西尼罗河病毒（WNV）是一种新兴的虫媒病毒，可感染人类和马。本研究对卡杜纳的 106 匹本地马和联邦首都地区的 78 只家鸡进行了横断面研究。使用 ID Screen®西尼罗河竞争酶联免疫吸附试验对 184 份血清进行了西尼罗河病毒抗 Pr-E 抗体筛查。马的总体阳性率为 92.45%，而家鸡的阳性率较高，为 7.69%。本研究发现，公马感染西尼罗河病毒的发生率明显高于母马，差异有统计学意义（p<0.05）。与种间西尼罗河病毒的发生情况相比，马比家鸡更容易感染西尼罗河病毒（OR 147）。这是首次在尼日利亚对家鸡感染西尼罗河病毒进行的血清阳性率研究。抗体的存在表明该病毒在人和动物中广泛传播，存在潜在的感染风险。为了了解尼日利亚西尼罗河病毒感染的流行病学情况，有必要在人类和动物领域实施监测。
