Background The COVID-19 global pandemic marked a pivotal moment in the public adoption of Artificial Intelligence (AI) and Big Data technologies, leading to increased utilization for public health surveillance, forecasting, and decision-making. While countries were quick to implement digital interventions, there is little cross-national evidence that shows how these interventions necessarily revealed enabling frameworks and recurring barriers. Purpose The purpose of this review is to evaluate how selected countries: India, the United States, Taiwan, and South Korea adopted AI and big-data technologies and practices during and after their COVID-19 experience, and to find transferable lessons and continuing best practices to inform the building of robust digital health governance and pandemic preparedness systems. Design/Methodology The review is based on the thirty (30) studies to assess digital health intervention strategies used in the four countries. Explorations uncovered themes such as data interoperability, public trust, legal and regulatory readiness, and the application of AI to routine health governance. Findings Taiwan and South Korea proved to be highly effective through centralized data infrastructures, legally framed constitutions, and high levels of public compliance. India and the US, although having large technology capabilities, demonstrated limited practices because of incomplete governance and unequal access. The cross-country synthesis underscores the importance of institutional memory, transparent digital policies, public-private partnerships, and inclusive digital ecosystems. This is a provisional file, not the final typeset article Limitations/Future Research This study is based on secondary data and literature review; it does not include primary fieldwork or stakeholder interviews. Future research should assess the longitudinal outcomes of AI-based public health strategies and their adaptability in diverse health system settings.
