Health, disease and susceptibility
- 3 things to know
- Paper 1
Overview
The World Health Organization definition of health as physical, mental and social well-being, communicable and non-communicable diseases and examples of each, pathogens, susceptibility, and how HIV, human papilloma virus, malnutrition and lung damage make other diseases more likely.

Questions from this subtopic
Each one with the model answer underneath.
- 1
How is health defined by the World Health Organization?
Model answer
Health is a state of complete physical, mental and social well-being, and not simply the absence of disease or infirmity.
- 2
State the three kinds of well-being included in the definition of health.
Model answer
Physical, mental and social well-being.
- 3
Explain why a person with no diagnosed illness might still not be considered healthy.
Model answer
Health also requires mental and social well-being, so someone free of disease can be unhealthy if either of these is poor.
- 4
Describe what is meant by mental well-being.
Model answer
Mental well-being means a person is free from mental illness and feels able to cope with the ordinary demands of life.
- 5
Suggest how a physically fit person could still have poor social well-being.
Model answer
They may be isolated or have poor relationships with the people around them.
- 6
Name the organisation whose definition of health includes physical, mental and social well-being.
Model answer
The World Health Organization.
