Résumé

Background: Infection prevention and control (IPC) is essential to prevent the spread of SARS-CoV-2 infection among health care workers (HCWs). This study assesses IPC practices and related risk of SARS-CoV-2 infection in 5 hospitals of Bamako, Mali. Methodology: This was a cross-sectional, descriptive and analytical study of hospital workers, including healthcare professionals, administrative and technical staff and medical students. Data were collected using a semi-structured questionnaire. Multivariable logistic regression was used to identify risk factors associated with COVID-19 infection. Findings: In 37.6% of cases, participants reported having attended infection prevention training. The use of hand sanitizer (82.8%) and a medical mask (62.2%) were the most common IPC practices. History of COVID-19 illness was reported by 64.3% of healthcare professionals, 47% of medical students and 33.6% of ATS staff. Covid-19 vaccination rates were 64% among healthcare professionals, 47% among ATS staff and 33% among medical students. The most significant risk factors associated with Covid-19 infection were male gender (aOR: 2.87, 95% CI 1.51-5.54), not always wearing a disposable cap (aOR: 3.36, 95% CI 1.12-10.18), not always wearing gloves (aOR: 3.36, 95% CI 1.15-7.78) and being involved in COVID-19 case management (aOR: 2.47, 95% CI 1.06-6.15). Conclusion: The finding shows a high risk of SARSCoV-2 infection related to weak IPC practices and highlight the need for appropriate training to ensure effective implementation of IPC measures in hospital setting.
