West Nile virus (WNV) and Usutu virus (USUV) are arboviruses transmitted by mosquito vectors. Whereas WNV is endemic in Israel, the Middle East, Europe, and in the Americas, data regarding the prevalence of USUV in the Middle East is limited. While both viruses share similar reservoirs and vectors, exposure of horses in the area to USUV have never been assessed. The aim of this study was to estimate the seroprevalence and co-exposure of WNV and USUV in horses in Israel. A total of 327 serum samples from healthy unvaccinated horses in Israel collected in 2018 were tested for neutralizing antibodies against WNV and USUV. Seroprevalence for neutralizing antibodies against WNV and USUV was 84.1% and 10.8%, respectively. Management and age were significantly associated with WNV and USUV seropositivity. This is the first report describing exposure of horses in Israel to USUV, which indicates that this zoonotic pathogen should be included in the differential diagnosis list of neuroinvasive disease in this country.
西尼罗河病毒（WNV）和乌苏图病毒（USUV）是通过蚊子媒介传播的虫媒病毒。虽然 WNV 在以色列、中东、欧洲和美洲流行，但关于中东地区 USUV 流行的数据有限。虽然这两种病毒有相似的宿主和传播媒介，但该地区的马群接触 USUV 的情况从未被评估过。本研究旨在评估以色列马群中 WNV 和 USUV 的血清流行率和共同暴露情况。从 2018 年收集的 327 份来自以色列健康未接种疫苗的马的血清样本中，检测了针对 WNV 和 USUV 的中和抗体。针对 WNV 和 USUV 的中和抗体血清阳性率分别为 84.1%和 10.8%。管理和年龄与 WNV 和 USUV 血清阳性率显著相关。这是首次报道描述以色列马群接触 USUV 的情况，这表明这种人畜共患病病原体应列入该国神经侵袭性疾病的鉴别诊断清单。
