In late January, the Korea Disease Control and Prevention Agency (KCDA) and the National Academy of Medicine of Korea (NAMOK) convened a joint public–private forum to examine strategies for sustainable and effective pandemic response [1]. The discussion extended beyond retrospective evaluation to focus on long-term system strengthening, including research on priority pathogens and Disease X, public health measures and human rights, accelerated vaccine platforms, strengthened research and development governance, and enhanced international cooperation. Recognition of the gap between ambition and implementation must translate into durable institutional reform and financing.

The 8 articles in this issue reinforce a consistent lesson: preparedness is systemic rather than episodic. A system dynamics analysis of the Republic of Korea’s in vitro diagnostics sector during COVID-19 demonstrates how research investment, regulatory agility, and public–private coordination shape epidemic trajectories. A nationwide dengue modelling study underscores regional heterogeneity and the need for locally adaptive predictive systems. A multi-city investigation of Salmonella enteritidis linked to widely distributed food products highlights the importance of integrated surveillance and genomic epidemiology. Two studies focusing on adolescents remind us that vulnerability accumulates long before infectious crises emerge. One identifies reciprocal associations between smartphone overdependence and anxiety among Korean youth, illustrating the interaction between digital exposure and mental health. Another demonstrates that clustering of non-communicable disease risk factors among adolescents in India is socially patterned and cumulative rather than individually isolated. Reviews addressing biotechnology approaches to overcoming cancer drug resistance and artificial intelligence applications in COVID-19 and long COVID management further indicate that technological innovation must be accompanied by advances in regulatory science, equity, and public trust. Taken together, these contributions reaffirm that preparedness extends beyond pathogen detection to encompass surveillance systems, regulatory science, innovation capacity, and the social determinants of health.

Financing remains decisive. Recent amendments to the International Health Regulations introduce a financial coordination mechanism intended to mobilize new and additional resources and to promote predictable and sustainable financing [2]. The draft World Health Organization Pandemic Agreement similarly emphasizes sustainable financing arrangements to support preparedness, capacity building, and equitable access to health products [3]. These developments converge on a shared conclusion: preparedness requires stable funding structures. However, international agreements do not automatically secure resources. Implementation ultimately depends on national legislation and budgetary decisions.

At a critical moment during the ongoing pandemic, the bereaved family of a private entrepreneur made a philanthropic contribution of 700 billion Korean won to support infectious disease research, infrastructure, and clinical facilities. The scale of this donation accelerated the expansion of national capacity. However, it also underscores a structural policy reality: essential preparedness functions should not depend on exceptional acts of philanthropy.

Although philanthropic funding can facilitate capital investment, long-term preparedness requires stable and predictable public financing. The construction of facilities represents only the first step. Sustainable operation—including workforce support, surveillance systems, research platforms, and deployment of medical countermeasures (MCMs)—depends on sustained annual governmental budget commitments. Without secure public financing, even newly established capacity may face structural financial pressures over time.

This reality calls for innovation in domestic financing mechanisms. The Republic of Korea previously operated outbound travel–associated contributions [1]; however, expansion of their statutory purpose diluted their original public health focus. The lesson is clear: financing mechanisms must have clearly defined objectives and be dedicated exclusively to preparedness functions. A preparedness contribution specifically earmarked for the prevention and management of imported infectious diseases—including surveillance, border health measures, and MCMs—would align funding with actual risk pathways. Infectious disease risks cross borders through mobility, and financing structures should reflect this transnational exposure. When transparently governed and reserved solely for preparedness purposes, such an approach could provide stable, long-term public financing insulated from annual budget volatility.

Future pandemics will require layered responses. Public health measures—including community mitigation strategies, distancing policies, and risk communication—remain foundational. MCMs must be supported by resilient health-care systems capable of surge response. Social policies that protect vulnerable populations and sustain public trust are equally essential. Preparedness therefore requires integration of public health, medical, and social strategies within coherent governance structures.

Implementation gaps persist not because knowledge is lacking, but because political attention fluctuates. Surveillance systems weaken as urgency fades. Research activity slows when budgets contract. Ambition recedes as collective memory of the crisis diminishes. The greatest threat after a pandemic may not be viral mutation but institutional complacency [4]. Preparedness is not a temporary programme activated during a crisis; it is a permanent national responsibility. International norms now recognize the necessity of sustainable financing. The remaining task is domestic institutionalization.

The recent joint forum convened by the KCDA and the NAMOK was therefore both timely and consequential. It reflected broad agreement that preparedness must extend beyond emergency response toward institutional reform. Yet agreement alone is insufficient. The decisive test lies in translating deliberation into legislation, dialogue into enforceable financing mechanisms, and policy discussion into sustained budgetary commitment. The opportunity created by timely discussion will narrow unless it is converted into concrete institutional action. Ultimately, preparedness will be secured not through debate, but through implementation.
