Epidemiologic Surveillance

Epidemiologic surveillance is the systematic collection, analysis, and interpretation of health-related data for monitoring disease patterns and health events in populations. It helps public health officials detect outbreaks, track disease trends, and evaluate the effectiveness of interventions. By continuously monitoring health data, such as infection rates or vaccination coverage, surveillance informs decisions to protect and improve community health. Essentially, it acts like a watchful eye on public health, enabling timely responses to emerging health threats and guiding policy-making to ensure a healthier population.
