Abstract

Introduction: Hepatitis B is a viral infection caused by the hepatitis B virus, which leads to inflammation of the liver. Infection with the hepatitis B virus (HBV) is a major public health problem, with more than 250 million chronically infected people worldwide at high risk of cirrhosis and hepato cellular carcinoma.

Objective: To contribute to a better understanding of vaccination coverage against the hepatitis B virus at the University Hospital of Abéché, Chad.

Material and Methods: This prospective analytical study was carried out on a population of 808 consenting patients aged between 14 and 60 years, from 1 April to 31 December 2023, using the enzyme-linked immunosorbent assay (ELISA) to determine antibodies to the hepatitis B virus surface antigen.

Results: Before our study, we found 3 cases (0.37%), including 2 (0.25%) males and 1 (0.12%) female, in a population of 808 samples. After our study, 44 vaccinated cases were identified with a vaccination rate of (5.44%), including 25 (3.09%) males and 19 (2.35%) females.

Conclusion: We note that ignorance of the hepatitis B virus and its transmission routes are factors that favourits spread in Abéché. This could be explained by the low rate of people vaccinated, with 3 cases (0.37%) before the study, after awareness-raising, vaccination coverage increased to 5.44% (44 cases vaccinated).
