Abstract

 Malaria remains one of the most significant global public health challenges, particularly affecting low- and middle-income countries in tropical and subtropical regions. Caused by Plasmodium parasites and transmitted by Anopheles mosquitoes, malaria poses a serious threat to human health, with children under five and pregnant women being the most vulnerable. Despite global efforts to reduce its prevalence, malaria continues to result in hundreds of thousands of deaths annually, most of them in sub-Saharan Africa. The disease's impact goes beyond mortality, contributing to high morbidity rates, weakened immune systems, and recurrent infections that affect physical and cognitive development, especially in children. Malaria also imposes a considerable economic burden on affected countries by increasing healthcare costs, reducing labour productivity, and hampering economic development. In many regions, repeated outbreaks strain already fragile healthcare systems, diverting resources from other essential health services. Public health interventions—including the use of insecticide-treated nets, indoor residual spraying, effective antimalarial drugs, and improved diagnostic tools—have led to significant reductions in malaria cases in recent decades. However, challenges such as drug resistance, insecticide resistance, and gaps in healthcare infrastructure continue to hinder eradication efforts. In conclusion, malaria remains a pressing public health issue that requires sustained investment, innovation, and international cooperation. Strengthening healthcare systems, expanding access to prevention and treatment, and investing in research are essential steps to reduce the global burden of malaria and move toward its eventual elimination.
