Summary Introduction: Hepatitis B is an important public health problem in the world and one of the forms of contagion would be through vertical transmission. Precose diagnosis allows the adoption of prophylaxis measures, which results in prevention in more than 90% of cases. Objective: To describe the prevalences of vertical transmission and compare two generations (mother/patient and patient/child). Method: This was a cross-sectional study, which included 101 patients. The interviews were performed through the application of the instrument of data collection and information of the physical file before the medical consultation. Results: The mean ± SD of age was 50.9 ± 13.1 years, the male gender predominated, with 56.4% of the patients, and the predominance was white, with 43.6%. Vertical transmission between mother and patient occurred in 17.8% and between patient and child, in 7.9%. In all of the eight cases of vertical transmission, the diagnosis was after the birth of children infected with HBV, and in 3/8 (37.5%), there was more than one case of infection by this mechanism per patient, totaling 13 children with the disease. Conclusion: There was a reduction in vertical transmission, showing that preventive measures were effective.
