Infection prevention and control in low- and middle-income countries: policy, practice, and implementation challenges in sub-Saharan Africa.

SUMMARYInfection prevention and control (IPC) programs are essential for safe healthcare; yet, implementation across sub-Saharan Africa remains constrained by chronic underfunding, weak water, sanitation, and hygiene (WASH) systems, limited laboratory capacity, and shortages of trained staff. Healthcare-associated infections (HCAIs) are presumed common, underreported, and often severe, with a disproportionate burden among hospitalized neonates and postpartum women, and they pose substantial risks to healthcare workers during outbreaks. Gram-negative pathogens such as Klebsiella, Escherichia coli, Pseudomonas, and Acinetobacter predominate, alongside methicillin-resistant Staphylococcus aureus, with widespread resistance to third-generation cephalosporins and other key antibiotics linking HCAIs directly to the region's antimicrobial resistance crisis. National and regional IPC policy frameworks have expanded, but facility-level implementation lags, reflected in patchy surveillance, weak accountability, and unreliable supplies of alcohol-based hand rub (ABHR), personal protective equipment, environmental cleaning materials, and core WASH and ventilation infrastructure. Evidence from sub-Saharan Africa shows that pragmatic multimodal strategies, locally produced ABHR, infrastructure designed to facilitate hand hygiene, role-specific training for clinical and non-clinical staff, and inclusive approaches involving families can improve practices and outcomes when supplies and supervision are sustained. A whole-system approach is required, prioritizing fit-for-purpose surveillance, stronger WASH and waste management services, development of an IPC workforce, and support for African-led innovation, including local manufacturing and context-specific decision-support tools. Implementing these actions through community engagement, empowered leadership at all levels, and sustainable financing is critical to reducing HCAIs, slowing antimicrobial resistance, and strengthening healthcare quality and resilience in sub-Saharan Africa.
