- Chronic conditions have become the dominant cause of disease burden because Australia has experienced an epidemiological transition over the past century where deaths from infectious diseases declined dramatically while chronic conditions increased.
- The reason for this is improved sanitation, vaccination programmes, antibiotics and public health measures have effectively controlled infectious diseases like tuberculosis and pneumonia.
- As a result, Australians now live longer but develop age-related chronic conditions such as cardiovascular disease, cancer, dementia and diabetes that require long-term management.
- This leads to chronic conditions now being responsible for the vast majority of deaths, with cancer, mental health conditions and musculoskeletal conditions emerging as the leading disease groups.
- Consequently, the healthcare system has shifted focus from treating acute infectious episodes to managing long-term chronic diseases that cause substantial disability and premature death.
- This demonstrates why modern Australia faces different health challenges compared to previous generations, requiring preventive strategies and lifestyle interventions rather than just medical treatments.
- Therefore, understanding this transition helps explain current patterns of morbidity and mortality in Australian populations.
