West Nile virus (WNV) is a flavivirus related to tick-borne encephalitis virus endemic in northeast of Poland. WNV circulates among wild birds, transmitted by wide range of haematophagous arthropods. Several mosquito species, especially Culex spp., can transmit WNV to humans. WNV is responsible for a broad range of clinical symptoms, from asymptomatic infection to severe encephalitis and polio-like myelitis. Elderly persons are at especially high risk of death and severe neurological complications, with mortality among patients over 65 years old with WNV-related encephalitis being as high as 35%. Warm and humid climate favors the spread of WNV, however, it can also be effectively transmitted in moderate climate zones. During the last decade a worldwide spread of WNV was observed, with establishment of new enzootic foci and growing number of human cases. WNV seems to be already present in several European countries, including Poland. We describe detection of anti-WNV IgM antibodies in serum of patient with acute febrile infection, which may constitute the first case of confirmed WNV infection in Poland.
西尼罗河病毒（WNV）是一种黄病毒，与波兰东北部流行的蜱传脑炎病毒有关。WNV在野生鸟类中传播，由多种吸血节肢动物传播。几种蚊子，尤其是库蚊属，可将WNV传播给人类。WNV可导致广泛的临床症状，从无症状感染到严重脑炎和脊髓灰质炎样脊髓炎。老年人死亡和出现严重神经并发症的风险尤其高，65岁以上患有WNV相关脑炎的患者死亡率高达35%。温暖潮湿的气候有利于WNV的传播，不过，它也能在温带气候地区有效传播。在过去十年中，观察到WNV在全球范围内传播，出现了新的动物疫源地，人类病例数量不断增加。WNV似乎已在包括波兰在内的几个欧洲国家出现。我们描述了在一名急性发热感染患者血清中检测到抗WNV IgM抗体，这可能是波兰确诊的首例WNV感染病例。
