Epidemiological transition

In demography, epidemiological transition refers to a change in the pattern of disease in a country away from infectious diseases towards degenerative diseases.

This transition is event as a country completes the process of modernisation or economic development. Less economically developed countries have higher rates of infectious diseases as standards of medical care a lower than that found in more economically developed countries.

In those more economically developed countries more people die from degenerative diseases as those infectious diseases such as chlorella and typhoid are easily treated causing more people to die from cancers as they live longer.
