Abstract

Health surveillance is a fundamental component of public health that involves the continuous, systematic collection, analysis, and interpretation of health data. This process helps identify health trends, detect outbreaks, and inform public health decisions and interventions. By understanding and implementing effective health surveillance systems, communities and governments can better protect and improve population health.Health surveillance refers to the ongoing monitoring of health-related data to track and assess the health status of populations. It encompasses a range of activities, including the collection of data on diseases, health behaviors, and risk factors, as well as the analysis of this data to identify patterns, trends, and emerging threats. The goal of health surveillance is to provide timely and u i c H e h N u s accurate information that can guide public health actions and policies.Effective health surveillance provides early detection of disease outbreaks, informs public health decision-making, tracks long-term health trends, and facilitates resource allocation. By analyzing and interpreting health data, public health officials can identify unusual patterns, guide interventions, and allocate resources efficiently to address pressing health issues. Surveillance data also supports public health research, contributing to the development of new prevention and control strategies.
