Abstract

Introduction: Viral hepatitis is among the main problems that affect public health globally. The knowledge of the clinical and epidemiological situation of hepatitis B and hepatitis C is necessary for the establishment of prevention and control strategies together with individuals and communities in vulnerable situations. Objective: To investigate the clinical and epidemiological aspects of the population affected by hepatitis B and hepatitis C from 2007 to 2014, in Fortaleza, Ceara, Brazil. Methodology: Descriptive, retrospective study involving data from the Notifiable Diseases Information System, with analysis of gender, age, race, illicit drug use, sex partnerships, tattoo/piercing, transfusion, dialysis and transplantation. Chi-squared tests were used for statistical analysis of the variables. Results: It was reported 779 cases of hepatitis B and 756 of hepatitis C. Regarding the HBV, 69.7% were male, 77.5% of brown color, and a median age of 36 years. Regarding risk factors, there was highlight for sexual practice and number of sex partners (p = 0.001), blood transfusion (p = 0.011) and use of tattoo/piercing (p = 0.011). As for HCV, 57.7% were male and the mean age was 46 years. As for risk factors, the injecting drug use (p = 0.001), the presence of three or more partners (p = 0.001) and the use of tattoo/piercing (p = 0.021) stood out. Regardless of gender, age or race and drug use, transfusions and age over 40 years increased the risk for hepatitis. There were still high percentages of missing data in several variables. Conclusion: This study contributes to alert the Brazilian health authorities on the importance of these infections and the need to expand and strengthen current health policies, and allows reflection on control strategies for hepatitis.
