The results of the Serbian national integrated West Nile virus (WNV) surveillance program conducted in 2018 and funded by the Serbian Veterinary Directorate are presented. The WNV surveillance program encompassed the entire territory of Serbia and was conducted by the veterinary service in collaboration with entomologists and ornithologists. The objective of the program was early detection of WNV circulation in the environment and timely reporting to the public health service and local authorities to increase clinical and mosquito control preparedness. The program was based on the detection of WNV presence in wild birds (natural hosts) and mosquitoes (virus vectors) and on serological testing of sentinel horses (WNV-specific IgM antibodies). The season 2018 was confirmed to be the season of the most intensive WNV circulation with the highest number and severity of human cases in Serbia ever reported. The most intense WNV circulation was observed in the northern and central parts of Serbia including Vojvodina Province, the Belgrade City area, and surrounding districts, where most positive samples were detected among sentinel animals, mosquitoes and wild birds. The majority of human cases were preceded by the detection of WNV circulation during the surveillance. The WNV surveillance program in 2018 showed satisfactory results in the capacity to indicate the spatial distribution of the risk for humans and sensitivity to early detection of WNV circulation in the environment.
本文展示了由塞尔维亚兽医局资助、于2018年开展的塞尔维亚全国西尼罗河病毒（WNV）综合监测项目的结果。WNV监测项目覆盖了塞尔维亚全境，由兽医服务部门与昆虫学家和鸟类学家合作开展。该项目的目标是尽早发现环境中WNV的传播情况，并及时向公共卫生服务部门和地方当局报告，以加强临床和蚊虫控制的准备工作。该项目基于对野生鸟类（自然宿主）和蚊子（病毒载体）中WNV存在情况的检测，以及对哨兵马的血清学检测（WNV特异性IgM抗体）。2018年被确认为WNV传播最为密集的季节，塞尔维亚报告的人类病例数量和严重程度均为历史最高。在塞尔维亚北部和中部地区，包括伏伊伏丁那省、贝尔格莱德市及其周边地区，观察到了最强烈的WNV传播，在这些地区的哨兵动物、蚊子和野生鸟类中检测到了大多数阳性样本。在大多数人类病例出现之前，监测中就已检测到WNV的传播。2018年的WNV监测项目在指示人类风险的空间分布以及对环境中WNV传播早期检测的敏感性方面取得了令人满意的结果。
