It includes the collection and analysis of health data to understand the who, what, when, where, and why of disease occurrence. Key areas of focus include:
Identifying the risk factors associated with diseases. Understanding the distribution and determinants of health-related states. Evaluating the efficacy of interventions and health policies. Monitoring and controlling the spread of diseases.
