Prevention

In medicine, prevention is any action which reduces the burden of humanity or morbidity from illness. This takes place at primary, secondary and tertiary prevention levels.

Primary prevention avoids the growth of a disease. Most population-based health support actions are primary preventive measures.Secondary prevention activities are intended at early disease detection, thereby increasing opportunities for interventions to prevent progression of the disease and emergence of symptoms.Tertiary prevention reduces the negative impact of an already recognized disease by restoring function and dipping disease-related complications.
