Epodemiologenic Transition Flashcards
(15 cards)
What is epidemiology the study of
Disease
What does the epidemiologic transition show
Shows how a countries death rates move from being dominated by infectious diseases to being dominated by chronic man made diseases
What happens as a country’s level of development improves in sanitation systems, medical access and healthcare provision
Epidemiologic transition changes from EXOGENETIC deaths to ENDOGENETIC deaths
What are exogenetic deaths
Death not due to lifestyle but due to disease spreading (not linked to genetics)
What are endogenetic deaths
Lifestyle and genetic diseases such as Parkinson’s and cancer
Stage 1 THE AGE OF PESDILENCE AND FAMINE
death rates remain very high in this stage as the causes of death are EXOGENETIC
Characterised by WIDESPREAD EPIDEMICS AND FAMINE
HIGH MORTALITY due to infectious diseases e.g chicken pox and small pox
Low life expectancy 20-40 years
Stage 1 UK description
UK in age of pestilence and famine until 1750
Example of stage 1 the age of pestilence and famine
Congo, Sudan and Uganda affected hugely by Ebola virus in 2014
Stage 2 THE AGE OF RECEDING PANDEMICS
Death rates fall rapidly due to developments in medical science and sanitation allow infectious diseases to be controlled
Mortality rates decrease
Life expectancy rises to 40-60 years
Stage 2 UK description
UK in this stage until 1850
Example of stage 2 the age of receding pandemics
Vietnam, Philippines and Thailand affected by SARS disease in 2003
Stage 3 AGE IF DEGENERATIVE AND MAN MADE DISEASES
Shift from EXOGENETIC to ENDOGENETIC deaths
Shift from infectious deaths to chronic and lifestyle related diseases.g heart disease, cancer and diabetes
Mortality rates stabilise at a LOWER level
Life expectancy rises further to 60+ years
Deaths more influences by ageing, lifestyle and genetic factors
Stage 3 UK description
UK in this stage from 1950 onwards
Example of stage 3 the age of degenerative and man made diseases
Nigeria moving into this stage in 2025
