What will be an ideal response?


The three levels of prevention are primary, secondary, and tertiary prevention.
• Primary prevention means averting the occurrence of disease and includes those measures that are applied or brought into effect before the disease is present.
• Secondary prevention means halting the progression of disease and preventing the sequelae of disease. It focuses on early diagnosis and prompt treatment of a health problem that could have serious impacts on the health of the individual.
• Tertiary prevention involves the prevention or limitation of the effects of the disease after it has been identified; this level of prevention operates on the premise that the presence of the disease does not mean that its course should be allowed to run unhindered.
