Introduction to Epidemiology

 

 

Goals in Epidemiology

Epidemiology is conceptually goal oriented and purposeful. As such, it focuses on three distinct objectives, viz. therapeutic, preventive, health maintenance and promotion.

1. Maintenance and promotion of the healthy state.
2. Preventive action - to inhibit the transition from healthy to the unhealthy state by avoiding and/or minimizing exposure to risk factors.
3. Curative (therapeutic) - increasing recoveries from unhealthy to the healthy state and thus minimizing mortalities.
