What Are the Applications of Diagnostic Methods in Epidemiology?

Diagnostic methods have multiple applications in epidemiology, including:

Surveillance: Monitoring the spread of diseases within populations to detect outbreaks early.
Screening: Identifying asymptomatic individuals who may have a disease, for early intervention.
Case Finding: Actively searching for cases in a population to control spread.
Epidemiological Research: Studying the distribution and determinants of health-related events.
Public Health Interventions: Evaluating the effectiveness of treatments and preventive measures.
