Resumo: | The aim of this study was to determine the prevalence of hepatitis B virus (HBV) infection in the Japreira indigenous community, Venezuela, and its relationship to age and gender. An intentional, non-probabilistic sample of 149 individuals was selected from a total of 300. All samples were studied for the presence of total HBV antibodies (total anti-HBc), and the positive samples were tested for HBV surface and "e" antigens (HBsAg, HBeAg). Overall prevalence rates of total anti-HBc were 72.9% in females and 81.1% in males. The highest prevalence of HBsAg was observed in males 26-35 years of age. Only four of the 44 HBsAg carriers were positive for HBeAg. The results showed a high endemic HBV infection rate and indicated that its spread begins at early ages. Sexual transmission may be the main route for spread of the virus. Crowding, close contact with bodily fluids, specific social practices, and features of the circulating viral strain among members of this community could be involved in the high chronicity observed in the Japreira indigenous community. |

Se detectó por métodos serológicos la presencia de anticuerpos totales del VHB (anti-HBc total), y en las positivas se investigó la presencia del antígeno de superficie (HBsAg) y del antígeno "e" del VHB (HBeAg). La prevalencia de anti-HBc total fue de 72,9% en el sexo femenino y 81,1% en el masculino, la prevalencia de HBsAg fue elevada (61,1%) en el sexo masculino, sólo cuatro de los portadores de HBsAg fueron positivos para HBeAg. Los resultados obtenidos indican un grado elevado de endemia para esta infección y que su diseminación comienza a temprana edad. El factor involucrado en la adquisición y diseminación del virus seria la vía sexual. Hacinamiento, contacto intercorpóreo con fluidos biológicos, prácticas sociales, y características de la cepa viral circulante podrían estar involucradas en la alta cronicidad observada en la comunidad indígena Japreira.Reports in Public HealthCadernos de Saúde Pública2008-05-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontext/htmlapplication/pdfhttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/3828Reports in Public Health; Vol. 24 No. 5 (2008): MayCadernos de Saúde Pública; v. 24 n. 5 (2008): Maio1678-44640102-311Xreponame:Cadernos de Saúde Públicainstname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZspahttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/3828/7767https://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/3828/7768Monsalve-Castillo, FranciscaEchevarría, José ManuelAtencio, RicardoSuárez, AnaisEstévez, JesúsCosta-León, LucianaMontiel, PilarMolero, TaniaZambrano, Marianainfo:eu-repo/semantics/openAccess2024-03-06T15:27:50Zoai:ojs.teste-cadernos.ensp.fiocruz.br:article/3828Revistahttps://cadernos.ensp.fiocruz.br/ojs/index.php/csphttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/oaicadernos@ensp.fiocruz.br||cadernos@ensp.fiocruz.br1678-44640102-311Xopendoar:2024-03-06T13:04:23.790281Cadernos de Saúde Pública - Fundação Oswaldo Cruz (FIOCRUZ)true |
