Abstract:
The 21st century has witnessed several significant viral outbreaks, beginning with SARS in 2002, followed by H1N1 in 2009, MERS in 2012, and the transformative COVID-19 pandemic in 2019. These events have underscored the critical need for rapid global responses, resilient healthcare systems, and effective international collaboration. Other notable viruses, including Ebola, Zika, Chikungunya, and Dengue, have further highlighted the interconnected challenges of global health. This review systematically examines literature from 2003 to 2023 to explore these pandemics, their impacts, and the global responses they elicited, with a focus on strategies for future pandemic preparedness. By emphasizing lessons learned—such as the value of early detection, swift response, and coordinated international efforts—the review seeks to enhance understanding of effective management and mitigation strategies. It highlights the vital role of robust healthcare infrastructure, comprehensive public health measures, and global cooperation in protecting against emerging infectious threats and safeguarding global health.
