Abstract 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.
