Preventive Medicine in a Global Health Context: Modern Realities and Future Directions (2025)

Abstract

Preventive medicine has emerged as the cornerstone of global public health in the 21st century, particularly in the aftermath of the COVID-19 pandemic, the escalating burden of non-communicable diseases (NCDs), accelerating climate change, and the growing threat of antimicrobial resistance (AMR). Global health systems are undergoing a paradigm shift from treatment-centered care to proactive, system-wide strategies emphasizing risk reduction, resilience, and population wellness. This paper adopts a narrative global policy review approach to examine the conceptual foundations, historical evolution, contemporary realities, and future directions of preventive medicine in 2025. Key global challenges—including vaccine inequity, mental health crises, digital health transformation, and the expanding role of artificial intelligence (AI) in precision prevention—are critically explored. Major policy frameworks, including Sustainable Development Goal 3 (SDG 3), the WHO Global Action Plan (2023–2030), the International Health Regulations (IHR 2005), the emerging Pandemic Treaty (2025), and the African Union’s Agenda 2063, are analyzed. The paper proposes an Integrated Global Preventive Medicine Framework (IGPMF) and demonstrates that prevention is fundamental to universal health coverage, climate resilience, health equity, and global health security in an increasingly interconnected world.
