Hepatitis E is an important public health problem mostly in developing but occasionally also in industrialized countries. Domestic and wildlife animals are considered reservoirs of the hepatitis E virus (HEV). Since no information on the prevalence of autochthonous HEV infections in human and animal in Poland is available, the aim of the study was to investigate the HEV seroprevalence of different wildlife species as potential virus reservoirs in the country. No HEV antibodies were found in any of the sera collected from the red deer (Cervus elaphus), European bison (Bison bonasus), roe deer (Capreolus capreolus), elk (Alces alces), fallow deer (Dama dama), sika deer (Cervus nippon), Tatra chamois (Rupicapra rupicapra tatrica) or brown bear (Ursus arctos). HEV-specific antibodies were detected in 44.4% (95% CI 38.3-50.7) serum samples originated only from wild boars. The percentage of seropositive wild boars differed significantly between the provinces and was positively correlated with the wild boar density and rurality of the area. This study showed that HEV circulates among wild boar population in Poland, and this species should be considered as an important reservoir of the virus.
戊型肝炎是一个重要的公共卫生问题，主要存在于发展中国家，但在工业化国家也偶尔出现。家畜和野生动物被认为是戊型肝炎病毒（HEV）的宿主。由于波兰缺乏关于人类和动物中本土戊型肝炎病毒感染流行情况的信息，本研究的目的是调查不同野生动物物种作为该国潜在病毒宿主的戊型肝炎病毒血清流行率。在从马鹿（Cervus elaphus）、欧洲野牛（Bison bonasus）、狍（Capreolus capreolus）、驼鹿（Alces alces）、黇鹿（Dama dama）、梅花鹿（Cervus nippon）、塔特拉羚羊（Rupicapra rupicapra tatrica）或棕熊（Ursus arctos）采集的任何血清中均未发现戊型肝炎病毒抗体。仅在野猪的血清样本中检测到戊型肝炎病毒特异性抗体，阳性率为44.4%（95%可信区间38.3 - 50.7）。血清阳性野猪的百分比在各省之间存在显著差异，并且与野猪密度和该地区的乡村程度呈正相关。本研究表明，戊型肝炎病毒在波兰的野猪种群中传播，该物种应被视为该病毒的重要宿主。
