Introduction: the health information system (HIS) in Burkina Faso has improved significantly in recent years. In order to suggest further improvements, we specifically assessed the HIS performance indicators of the epidemic surveillance system from the perspectives of the stakeholders., Methods: we conducted a mixed methods study to assess the performance through timeliness and completeness indicators, strengths, and weaknesses of the HIS in Burkina Faso with specific focus on epidemic surveillance in the health districts of Dandé and Tenkodogo for the period of 2016 to 2019., Results: fewer than 35% of health districts were able to report at least 90% completeness of community reports since 2017. In 2018, four districts did not exceed 1% completeness of community reports. Some concerns remain related to a need of local support and inter-sectoral collaboration. The technical and organizational factors affect process and performance of the system directly or indirectly through behavioral determinants., Conclusion: the ability to measure the performance of all health facilities and to share all community reports online are challenges for the health system in Burkina Faso. New technologies, training-sensitization, and the involvement of actors with influence on social or behavioral change could help to ensure dynamic performance, if perceptions of actors are taken into account., Competing Interests: The authors declare no competing interests., (Copyright: Cheick Omar Diallo et al.)

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., Competing Interests: Les auteurs ne déclarent aucun conflit d´intérêts., (Copyright: Pengdewendé Maurice Sawadogo et al.)
