Resumo

Introduction: Viral hepatitis is a group of diseases that present high hepatotropism and are related to liver dysfunctions, having either an acute or a chronic course. Their worldwide epidemiology is diverse, with several endemic places, such as South America. The objective of this study was to analyze the epidemiology of viral hepatitis in Brazil, in order to better understand its pattern of distribution and evolution.

Method: A temporal aggregation study was conducted using the Viral Hepatitis Database of the Brazilian Ministry of Health. The serological markers used were HBsAg and anti-HCV for hepatitis B and C, respectively. Mortality data were collected from the Mortality Information System for deaths attributed to viral hepatitis. The period analyzed was from 2007 to 2016/17.

Results: The incidence was 7.88 (95% CI, 7.30-8.45) for hepatitis B and 11.9 (95% CI, 11.15-12.65) for hepatitis C. Mortality attributed to viral hepatitis was 1.61 (95% CI, 1.35-1.87) deaths per 100,000 people. An analysis of municipal distribution data showed several endemic areas. The Brazilian regions most affected by hepatitis B virus were the northern and southern borders, Santa Catarina coast and Espírito Santo state, while hepatitis C virus was mostly present in metropolitan areas such as Porto Alegre and São Paulo.

Conclusion: Viral hepatitis has a diverse geographic distribution in the Brazilian territory, with highly endemic areas. The distribution differs between hepatitis B and hepatitis C viruses.
