First Detection of Hepatitis B Virus Subgenotype A5, and Characterization of Occult Infection and Hepatocellular Carcinoma-Related Mutations in Latin American and African Immigrants in Brazil.
Int J Mol Sci
August 2024
Article Synopsis
- This study investigates the molecular characteristics of hepatitis B virus (HBV) among socially vulnerable immigrants in Brazil to assess the introduction of rare HBV strains.
- Researchers tested serum samples from 102 immigrants with positive HBV serology, discovering various HBV subgenotypes, including the first report of subgenotype A5 in Brazil.
- The findings highlight the need for improved prevention and control strategies by understanding the genetic diversity of HBV within immigrant communities, which could enhance public health initiatives for both immigrants and the broader population.
Objective: To estimate the prevalence of Sexually Transmitted Infections (STIs) in immigrants and refugees living in the metropolitan region of Goiânia, Goiás.
Method: This is a cross-sectional and analytical study. Data collection was carried out from July 2019 to January 2020 and 308 immigrants and refugees were included in the sample.
Human T-lymphotropic virus 1/2 infection among immigrants and refugees in Central Brazil, an emerging vulnerable population.

Introduction: Migratory flows play a significant role in the spread of human T-lymphotropic virus 1/2 (HTLV-1/2). In the last decade, a substantial migration of individuals occurred from Haiti and Venezuela to Brazil. However, data on the prevalence of HTLV-1/2 infection among these international migrants in Brazil are scarce.

Given the lack of information in Brazil, this study aimed to estimate the prevalence of infections caused by hepatitis B and C viruses and factors associated with hepatitis B in immigrants and refugees residing in central Brazil. An observational, cross-sectional, and analytical study was conducted from July 2019 to January 2020 with 365 immigrants and refugees.

Methods: Overall, 355 individuals were interviewed, and blood samples were tested for anti-HAV and anti-HEV IgG. Anti-HEV-positive samples were similarly tested for HEV RNA.
Epidemiology of HIV, syphilis, and hepatitis B and C among manual cane cutters in low-income regions of Brazil.
BMC Infect Dis
November 2018
Background: In recent decades the epidemic of asymptomatic sexually transmitted infections has extended deep into Brazil, including small towns and rural areas. The purpose of this study was to investigate the epidemiology of HIV, syphilis, and hepatitis B (HBV) and hepatitis C viruses (HCV), and to evaluate immunization coverage against hepatitis B in a group of rural workers in Brazil.
Methods: In 2016, a cross-sectional study was conducted with 937 manual sugarcane cutters of the Midwest and Northeast Regions of Brazil.
