The convergence of public health and national security has grown progressively following worldwide health emergencies. The objective of this research is to comprehensively examine the role of public health in national security frameworks, both in theory and in practice. The study employs a doctrinal approach to examine the incorporation of public health policies into national security objectives by analyzing current literature, legislative frameworks, and case studies. The discussion emphasizes the difficulties and possibilities that arise from this convergence, namely in terms of readiness for pandemics and prevention of bioterrorism. The findings of the paper indicate that strong public health systems are crucial for maintaining national security. It concludes by providing policy proposals aimed at improving health security.
