The significance of surveillance and early warning systems in identifying and addressing emerging diseases is paramount in ensuring timely and effective pandemic preparedness and response. These systems form the backbone of public health infrastructure, enabling health authorities and governments to detect threats early, implement appropriate interventions, and prevent the rapid spread of infectious diseases across populations and borders. Surveillance systems serve as a continuous process of data collection, analysis, interpretation, and dissemination of health-related information that is essential for planning, implementation, and evaluation of public health practices. Early warning systems (EWS), on the other hand, are mechanisms designed to detect signals of potential disease outbreaks or public health emergencies in real-time, facilitating prompt risk assessment and rapid response. Emerging diseases, defined as infections that have newly appeared in a population or have existed but are rapidly increasing in incidence or geographic range, pose significant challenges due to their unpredictable nature, potential severity, and global impact. The COVID-19 pandemic is a clear illustration of how the absence or inefficacy of early detection and global cooperation can exacerbate the magnitude of a health crisis. Thus, the integration of robust surveillance and early warning systems is indispensable in the modern public health paradigm. One of the primary significances of surveillance and early warning systems is early detection of abnormal health events.
