Answers
Answer:
Disease prevention is a procedure through which individuals, particularly those with risk factors for a disease, are treated in order to prevent a disease from occurring. Treatment normally begins either before signs and symptoms of the disease occur, or shortly thereafter.Disease and disability are affected by environmental factors, genetic predisposition, disease agents, and lifestyle choices, and are dynamic processes which begin before individuals realized they are affected. Disease prevention relies on anticipatory actions that can be categorized as primal,primary, secondary, and tertiary prevention.Preventing disease through routine vaccination can improve both health and economic stability. “Increased investments on immunization in low- and middle-income countries could avert up to 36 million deaths and 24 million cases of impoverishment due to medical costs,” UNICEF reports.
There are three levels of prevention: improving the overall health of the population (primary prevention) improving (secondary prevention) improving treatment and recovery (tertiary prevention).
