A retrospective and cross-sectional study was carried out on blood donors from Piauí State located at Northeastern Brazil to evaluate the prevalence of Hepatitis E Virus (HEV) infection. Serum samples were tested for anti-HEV IgG and IgM using electrochemiluminescence and HEV RNA was tested using real time PCR. A total of 890 individuals were included with median age of 33.4 years and most of them were male and lived at Mid-Northern region of the State. Prevalences of anti-HEV IgG and IgM were 1.35 % and 0.11 %, respectively. None HEV-RNA was detected. This study demonstrated low prevalence of HEV infection in blood donors in this region.
对位于巴西东北部皮奥伊州的献血者进行了一项回顾性横断面研究，以评估戊型肝炎病毒（HEV）感染的流行情况。使用电化学发光法检测血清样本中的抗HEV IgG和IgM，并使用实时PCR检测HEV RNA。共纳入890人，中位年龄为33.4岁，其中大多数为男性，居住在该州中北部地区。抗HEV IgG和IgM的流行率分别为1.35%和0.11%。未检测到HEV-RNA。这项研究表明该地区献血者中HEV感染的流行率较低。
