Establishing a Preparedness Program: Lessons From COVID-19 to Strengthen Global Strategies for Future Pandemics
Year: 2025
Type: article
Abstract: This study aimed to evaluate the global response to the COVID-19 pandemic, identify preparedness gaps, and propose strategies to strengthen resilience for future health crises, drawing on the natural history of SARS-CoV-2 and epidemiological models. The research team conducted a narrative review with a descriptive analysis supported by case examples and modeling. We synthesized published literature, official reports, and surveillance data, analyzing COVID-19 transmission using the epidemiological triangle model. Comparative case studies from South Korea, New Zealand, and the United Kingdom were examined to assess intervention effectiveness. National surveillance systems, outbreak response mechanisms, and public communication strategies were critically reviewed. Our findings show that disparities in testing, data transparency, and infrastructure shaped outcomes globally. Surprisingly, many high-income countries underperformed despite prior preparedness rankings. Countries implementing early lockdowns, equitable vaccine rollouts, and consistent public messaging achieved better control. However, asymptomatic transmission, weak surveillance integration, and delayed policy actions hindered containment. Vaccine inequity and fragmented data systems further limited coordinated response. Future preparedness must emphasize early interventions, sustained surveillance investment, transparent communication, and equitable access to care. Lessons from COVID-19 underscore the value of multidisciplinary response teams, international data sharing, and targeted testing strategies to mitigate the impact of future pandemics.
