Abstract

Introduction :
viral hepatitis B is a major public health problem. Sub Sahran African is paying a heavy price despite the existence of an effective vaccine. This work aims to determine the prevalence and risk factors associated with viral hepatitis B in unvaccinated health workers.

Methods :
was a analytical cross-sectional study carried out at Military Teaching Hospital – University and hospital center (HIA-CHU) of Parakou from October 1st, 2019 to February 28th, 2020. Health worker present during the study period and willing to participate after informed consent was included. Sociodemographic data and risk factors were assessed. Blood samples from were tested for HBsAg using a rapid diagnostic test. Positive results were confirmed by ELISA.

Results :
Eighty-six (86) unvaccinated health workers took part in this study (mean age 34.1 ± 6.1y; sex ratio 1.04). Among them, 82 (95.4%) did not know their B viral status. Eighteen (18) unvaccinated health workers were HBsAg carriers, representing a prevalence of 20.9%. Risk factors associated with HBsAg carriage were an age, a history of jaundice, blood exposure accidents and the practice of scarifications.

Conclusion :
The prevalence of HBV infection among unvaccinated healthcare workers is very high. Unvaccinated healthcare workers are exposed to several risk factors. Improved prevention is recommended, as is appropriate management of subjects with viral hepatitis.
