Global Health Security: How Public Health Systems are Preparing for Future Pandemics

Abstract

Global health security refers to the ability of countries and international organizations to prevent, detect, and respond to health threats, including pandemics, that can cross borders and cause widespread illness and death. The COVID-19 pandemic underscored the importance of robust public health systems and highlighted gaps in preparedness and response. This article explores how public health systems around the world are preparing for future pandemics by strengthening health infrastructures, improving surveillance systems, enhancing international collaboration, and addressing inequities in healthcare access. Through an analysis of current strategies, challenges, and future opportunities, this paper discusses the steps necessary to safeguard global health security and reduce the impact of emerging infectious diseases.
