Lesson 1 Introduction
According to the World Health Organisation (WHO), Health is:
“a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity”.
Physical health (ability to maintain health or recover to a healthy state after disease) is the main focus of this unit.
- Diseases can influence, change, or even disrupt some of your body functions, including even after recovery.
- Diseases can even influence your mental and social well-being.
Diseases can be classified based on the way someone can get them
Communicable diseases
- An ill person/animal/plant can pass the disease to another person
- Caused by a pathogen
Non-Communicable diseases
- Not transmitted between humans
- Caused by genes, environment, behaviour
