ABSTRACT

This review explored the efficacy of insecticide-treated bed nets (ITNs) in reducing malaria incidence among children under five in rural Sub-Saharan Africa, a region disproportionately affected by the disease. Malaria, transmitted by Anopheles mosquitoes, remains a leading cause of morbidity and mortality, particularly in vulnerable populations. ITNs, serving as both a physical barrier and a vector control tool, have demonstrated significant success in lowering malaria prevalence and mortality rates. Studies reveal that ITNs can reduce malaria incidence by up to 50% and mortality by approximately 20%, highlighting their critical role in malaria control programs. However, ITN effectiveness faces challenges such as insecticide resistance, low utilization rates, and issues related to durability and maintenance. These obstacles were compounded by socio-economic barriers and environmental factors prevalent in rural communities. Strategies to enhance ITN impact include developing next-generation ITNs, increasing community education to improve utilization, and integrating ITNs with other malaria control interventions. Successful implementation programs, such as those in Rwanda and Ethiopia, provided valuable insights for scaling ITN distribution. Using a narrative review methodology, this article synthesized existing research to provide a comprehensive understanding of ITN efficacy, challenges, and future directions. It underscored the need for sustained investment and innovation to optimize ITN use and accelerate progress toward malaria elimination in Sub-Saharan Africa.
