INTRODUCTION
Prevalence of hepatitis E virus (HEV) infection and associated factors were investigated in rural settlements in Central Brazil.
METHODS
A total of 464 settlers were interviewed, and serum samples were tested for anti-HEV IgG/IgM. Positive samples were tested for HEV RNA.
RESULTS
Sixteen participants (3.4%; 95% CI 2.0-5.7) were positive for anti-HEV IgG. None was positive for anti-HEV IgM. HEV RNA was not detected. Dwelling in a rural settlement for >5 years was associated with HEV seropositivity.
CONCLUSIONS
The results revealed the absence of acute infection and a low prevalence of previous exposure to HEV.
引言
对巴西中部农村定居点戊型肝炎病毒（HEV）感染的患病率及其相关因素进行了调查。
方法
共采访了464名定居者，并对血清样本进行抗HEV IgG/IgM检测。对阳性样本进行HEV RNA检测。
结果
16名参与者（3.4%；95%可信区间2.0 - 5.7）抗HEV IgG呈阳性。抗HEV IgM均为阴性。未检测到HEV RNA。在农村定居点居住超过5年与HEV血清阳性有关。
结论
结果显示不存在急性感染，既往接触HEV的患病率较低。
