The present communication deals with the analysis of 14 cases of Powassan encephalitis. As shown in this study, the course of this infection may be accompanied by symptoms indicating the presence of cerebral and meningeal lesions (in 7 cases meningoencephalitic forms with one fatal outcome and in 2 cases meningeal forms were registered) or take febrile and inapparent forms (5 cases). Powassan encephalitis was found to give characteristic symptoms of cerebellovestibular lesions, differentiating this disease from tick-borne encephalitis (TBE). The cases of mixed infections caused by TBE virus, Powassan encephalitis virus and tick-born Borrelia were found to be possible.
本通讯报道了对14例波瓦桑脑炎病例的分析。如本研究所示，这种感染过程可能伴有表明存在脑和脑膜病变的症状（7例为脑膜脑炎型，1例死亡；2例为脑膜型），或者表现为发热和无症状形式（5例）。波瓦桑脑炎具有小脑前庭病变的特征性症状，可将该疾病与蜱传脑炎（TBE）区分开来。发现存在由TBE病毒、波瓦桑脑炎病毒和蜱传疏螺旋体引起的混合感染病例。
