Última Hepatotropic viruses in the Brazilian Amazon: a health threat BJID Paraná,Raymundo; Vitvitski,Ludmila; Pereira,Joao Eduardo. Viral Hepatitis B, C and D are a serious public health problem in Brazil and other South American countries, mainly in the Amazonian region. Despite the paucity of clinical and epidemiological studies, a high prevalence of Hepatitis viruses has often been described in this area. Genotype F of Hepatitis B and Genotype III of Hepatitis D have been found to be quite prevalent in this area and preliminary studies have implicated both genotypes in carcinogenesis and peculiar pathogenic liver mechanisms. Initial epidemiological studies have further demonstrated a high prevalence of Hepatitis C in the western Brazilian Amazon. The geographic, cultural, ethnic and environmental aspects of this region may favor hepatotropic virus dissemination, as well as rendering...

In the village of Cavunge, located in a dry tropical, semiarid rural region of the state of Bahia, Brazil, a sentinel study on viral hepatitis is underway. We report on the first part of the study. The objective of this study was to determine the prevalence of serological markers for hepatitis A, B and C in the village. Cross sectional study. Blood samples were tested for serological markers of hepatitis A (HAV), B (HBV) and C (HCV) through ELISA-III assay. In HBsAg and anti-HCV carriers, HCV-RNA and HBV-DNA were checked by PCR. The prevalence of anti-HAV IgG was 83.3% (1,210/1,452), being higher among residents from the village (87.4%) than in residents from the rural area (79.5%); it also higher among individuals older than 10 years of age.
