Evolution of Disease
Evolution of Species
Mortality has no fixed upper limits. Thus if fertility approached its upper maximum, depopulation would still occur.
During the epidemiologic transition, a long-term shift occurs in mortality and disease patterns whereby pandemics of infection are replaced by degenerative and man-made diseases...
Characterized by high mortality rates, wide swings in the mortality rate, little population growth and very low life expectancy
Epidemics become less frequent, infectious diseases in general become less frequent, a slow rise in degenerative diseases begin to appear
The shifts in disease patterns in the 19th century were primarily related to changing SES.With the 20th Century more related with disease control activities independent of SES:e.g. Mexico, China
14 years primarily related to changing SES.
Increasing Life Expectancy and primarily related to changing SES.
