Health and disease are interlinked but have different definitions.
Health refers to the state of physical and mental well-being whereas a disease is a cause of ill health. However, diseases are not the only factor that can cause ill health; diet, stress and lifestyle factors can also have an impact.
Diseases are further categorized into either communicable or non-communicable, depending on whether the disease involves a pathogen.
