[Hepatitis B in the healthcare settings: knowledge and factors associated with vaccination among healthcare professional students in the National School of Public Health of Ouagadougou, Burkina Faso based on a cross-sectional survey].

Introduction: hepatitis B is a severe disease that can be prevented by vaccination. However, few healthcare professionals, a group at high risk of contamination, are vaccinated against this disease in Burkina Faso. We conducted a study of healthcare professional students to evaluate their knowledge and factors associated with their propensity toward Hepatitis B vaccine.

Methods: we conducted a cross-sectional, descriptive and explanatory study of 410 healthcare professional students of the National School of Public Health of Ouagadougou, Burkina Faso. Data were collected from 26 to 1 June 2020. Participants were randomly selected and were given a self-administered questionnaire.

Results: less than one third of healthcare professional students were fully vaccinated against hepatitis B. A small proportion of healthcare professional students were aware of the three modes of transmission (46.6%), risks of exposure in the healthcare setting (31.2%) and disease complications (26.6%). Multivariate logistic regression showed that healthcare professional students´ awareness of the risks of exposure in the healthcare setting and complications of the disease were statistically associated with hepatitis B vaccination.

Conclusion: strengthening the knowledge of healthcare professional students is necessary to improve vaccination coverage in this risk group.
