RESUMO

Infection by HBV and HCV is a worldwide public health problem, which infect and result in necrosis and inflammation in the liver. When the infection persists, contribute to progression liver cirrhosis and hepatocellular carcinoma. In Brazil, prevalence of HBV is moderate (2% to 7%), with low infection rate in Southern, middle rate in Northeast and Southeast, and high prevalence in the Amazon region, in the Espírito Santo, and in west of Santa Catarina. Little data are available on the seroprevalence and of risk factors for HBV and HCV infections in Brazil, mainly who had received hepatitis B vaccine. Knowing the prevalence of HBV and HCV in the general population is crucial for anticipating their future impact on the health system and for ensuring an adequate allocation of financial resources. The present study aimed to determine the prevalence of HBV (HBsAg, anti-HBc and anti-HBs) and HCV (anti-HCV) markers in voluntary students to aged 10 to 15 years. A total of 410 students participated in the study and 353 students vaccination document was check. Blood samples were collected and were tested four serological markers through Microparticle Enzyme Immunoassay (MEIA-Abbott AxSym System Laboratories). The results show that the overall HBsAg prevalence was 0.5% (2/410) and anti-HBc prevalence was 1% (4/410). The overall prevalence of anti-HBs was 81,22% (333/410), 36,10% (148/410) adolescent had anti-HBs concentrations <10 IU/L and 45,12%(185/410) had anti-HBs concentrations = 10 IU/L. The prevalence of anti-HBs in vaccinated student that received 3 or 4 doses series was 94,48% (325/344) achieving the vaccination coverage goal of Health Department. None anti-HCV prevalence was observed. The results from study indicate that the prevalence of HBV and HCV markers was low in voluntary adolescents from Itajaí, Santa Catarina, aged from 10 to 15 years old. Moreover, the high vaccination coverage and prevalence of anti-HBs markers show the success of the vaccination program against hepatitis B initialized in 1993, that need to be maintained and expanded, but also that other prevention forms should be developed to prevent the HBV and HCV transmission.
