Soroprevalência e fatores de risco para as hepatites virais B e C na comunidade ribeirinha de Pacuí-Cametá/PA

Abstract

Viral hepatitis is an important problem public health in Brazil, mainly in the northen region wich there are few studies in this area especiallu in coastal communities , due to difficult acess. The research aimed to determine the prevalence of viral hepatitis B and C in the Amazon river town, Pacui Island, city of Cametá, Para State, and to investigate the socio-economic characteristics and major risk factor that this community is exposed. Comprised a total of 181 volunteers, these blood samples were collected and applied an epidemiological questionnaire. The research of specific serological markers was perfomed by commercial ELISA kits for detection of HbsAg, anti-Hbc, anti-Hbs and anti-HCV. In patients reagent for HCV wad done RT-PCR for identificantion of viral RNA. In the analysis of serological markers for hepatitis B, no reactivity for HBsAg was observed, rates of 1,1% (2 – 181) for anti-HBc and 19,3% (35 – 181) for anti-Hbs. The seroprevalence of hepatitis C was 8,8% (16 – 181), 16 samples of reagent, 37,5% (6 – 16) hac HCV RNA. In the analysis of major risk factors stood out as not using condoms, sharing of nail clippers, hospitalization, multiple sexual partners and familiar with hepatitis B or C. It was observed that vaccination coverage against HBV is low in this community, and we found a high prevalence of HCV. The community had no knowledge about viral hepatitis B and C and not on the risk factors to which it is exposed.
