Overview

Scoping review examines hepatitis E virus prevalence and transmission modes in Brazil, suggesting zoonotic links.

Key Points

  • HEV infection shows significant prevalence variation across Brazil, with higher rates in the South and Southeast regions.
  • Among 57 studies, 45 involved humans, with IgG prevalence ranging from 0.5% in the North to 59.4% in the South.
  • The review analyzed epidemiological data using the Joanna Briggs Institute framework, focusing on transmission modes and circulating genotypes.
  • Circulating genotype HEV-3 was consistently found across regions, indicating a strong zoonotic transmission link through swine.
