How Can Disease Surveillance Improve Public Health?

Surveillance is foundational in epidemiology, as it provides critical data for detecting outbreaks, monitoring disease trends, and evaluating control measures. Effective surveillance systems include:
Passive Surveillance - Routine reporting of cases by healthcare providers.
Active Surveillance - Proactive case finding and data collection.
Sentinel Surveillance - Monitoring specific sites or groups for early detection of outbreaks.
These systems help identify emerging health threats, allocate resources effectively, and shape intervention strategies.
