Scientific evidence indicates that hepatitis E virus (HEV) infection is a zoonotic disease. Domestic pigs and wild boars are the main animal reservoir for HEV worldwide. The aim of this study was to analyze the seroprevalence of HEV infection among wild boars in western Bulgaria. Serum samples from 240 wild boars from two regions of the country (northwestern and southwestern) were tested for anti-HEV Immunoglobulin G (IgG) antibodies. The overall HEV seroprevalence was 40.8% (98/240); northwestern region 40.0% (48/120); southwestern region 41.7% (50/120). HEV seropositivity in the southwestern region was higher than in the northwestern region: odds ratio = 1.071 (95% confidence interval: 0.640-1.793). This research provided the first seroprevalence study to HEV in wild boars from western Bulgaria.
科学证据表明，戊型肝炎病毒（HEV）感染是一种人畜共患病。全球范围内，家猪和野猪是 HEV 的主要动物宿主。本研究旨在分析保加利亚西部野猪中 HEV 感染的血清流行率。对来自该国两个地区（西北部和西南部）的 240 头野猪的血清样本进行了抗-HEV 免疫球蛋白 G（IgG）抗体检测。总的 HEV 血清流行率为 40.8%（98/240）；西北部地区为 40.0%（48/120）；西南部地区为 41.7%（50/120）。西南部地区的 HEV 阳性率高于西北部地区：优势比=1.071（95%置信区间：0.640-1.793）。这项研究提供了保加利亚西部野猪中 HEV 的首次血清流行率研究。
