Epidemiological transition

The video discusses the epidemiological transition from infectious to chronic diseases, focusing on Omran's theory of three phases: pestilence and famine, receding pandemics, and degenerative diseases. It highlights the challenges faced by developing countries due to rapid transitions and social disparities, leading to a double burden of disease. The future of epidemiological transition is explored, emphasizing the re-emergence of infectious diseases driven by antimicrobial resistance and zoonotic infections.

What is the primary focus of the epidemiological transition?

• The shift from non-communicable to communicable diseases

• The reduction of chronic diseases in high-income countries

• The shift from infectious to non-communicable diseases

• The increase in birth rates globally

During the 'Pestilence and Famine' phase, what was a major cause of death?

• Cancer

• Obesity

• Heart disease

• Infectious diseases

What significant change occurred during the 'Age of Receding Pandemics'?

• Decrease in global population

• Increase in chronic diseases

• Massive reduction in infectious diseases

• Rise in global temperatures

What has contributed to the rise of chronic diseases in the 'Degenerative Disease' phase?

• Reduction in global trade

• Decreased access to healthcare

• Increased life expectancy and lifestyle changes

• Improved sanitation

What percentage of global deaths are attributed to non-communicable diseases?

• 80%

• 70%

• 60%

• 50%

What is a major driver for the re-emergence of infectious diseases?

• Reduction in population density

• Decreased global travel

• Antimicrobial resistance

• Improved healthcare systems

What is a zoonotic infection?

• An infection that only affects plants

• An infection transmitted from humans to animals

• An infection that jumps from animals to humans

• An infection that is resistant to all treatments
