The characteristic of high-risk behavior from the prison public contributes for a high prevalence of diseases transmitted by sexual or parenteral route. Considering the high rates of hepatitis B and C in prisons, this study aims to identify the main risk factors, the prevalence of these diseases and the founded genotypes. This study is an analytical cross-sectional. The sample was composed of 313 inmates from the Female Recovery Center in the State of Pará, wich agreed to participate of this study and were in good physical and mental health. Blood samples were collected and applied a socio-epidemiological questionnaire. The socio-epidemiological analysis showed a predominance of the age group 25-34 years (44.8%), marital status single (55%), incomplete elementary school education (68%) and 1 minimum family wage (65% ). The variables of age and education showed a statistically significant correlation with markers of HBV infection. Risk factors such as cutting and piercing material sharing, tattoo, hospitalization, dental surgery and not condom use showed high frequency. The variable of hospitalization showed statistics association with markers of HBV infection. Serology by ELISA assay showed that 3% were positive for HBsAg, 15% reagents for Anti-HBc, 23% reagents for anti-HBs and 5% for anti-HCV. In the genotyping of samples was found wich from of 10 HBsAg positive samples, 4 samples had undetectable genotype, in 5 samples the genotype E was identified (still not mentioned in Brazil), and in 1 was identified the genotype F (third most prevalent the country) ; from the 17 positive samples for Anti-HCV, 41.2% had undetectable genotype, this same percentage was obtained for genotype 1, and in 17.6% of samples was found the genotype 3, in agreement with the Brazilian standard described in literature.

Prevalência e fatores de risco para a Hepatite viral B em pacientes submetidos a hemodiálise na cidade de Belém/PA – Brasil
(Universidade Federal do Pará, 2014) FREITAS, Andrei Silva; MARTINS, Luisa Caricio; http://lattes.cnpq.br/1799493244439769
Hepatitis B virus (HBV) infection is a major worldwide health problem. Recent studies have reported that patients with chronic kdney desease on hemodialysis are at high risk of acquiring HBV. The research was conducted in three Hemodialysis Centers in the city of Belém, Pará , Northern Brazil . The objective of this study was to describe the prevelence of HBV infection associated risk factors. A total of 298 patients were interviewed in three hemodialysis centers. Serum samples were screened for HBV serological markers by ELISA ( Enzyme-linked Immunosorbent Assay) . A percentage of 26.85 % (80/ 298) of individuals who have come into contact with HBV ( 23/298 HBsAg reagent and 67/298 reagent for anti - HBc Total) was observed . Individuals who have multiple sexual partners , who received blood transfusion , sharing nail clippers and those on hemodialysis for more than five years have a higher risk for acquiring HBV.

Soroprevalência e fatores de risco para as hepatites virais B e C na comunidade ribeirinha de Pacuí-Cametá/PA
(Universidade Federal do Pará, 2010) OLIVEIRA, Claudia Suellen Ferro de; MARTINS, Luisa Caricio; http://lattes.cnpq.br/1799493244439769
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.
