Disease Spread in Poverty and Wealth
Transcript of Disease Spread in Poverty and Wealth
Public Health of Slums
The World Health Organization (WHO), many current urban slums are characterized as “islands of informal economics, social exclusion, and underdevelopment"*
"Slums are the prerequisite consequences of urbanization"**
One third of the urban population lives in urban slums.
The Public Health of the Peasantry
Life during the medieval period was heavily dependent on social class.
The lowest social class was known as the peasantry, a large population of people living in extreme poverty.
The World Data Bank characterizes extreme poverty as an average daily consumption of $1.25 or less, and surviving on the edge of subsistence.
“Their faces were pale, their bodies lean, their stomachs bloated, ‘their voices thin and piping like the voices of birds’”*
The large peasant population lived in very poor health due to:
Poor, dense, and overcrowded villages
Disease Spread in Poverty and Wealth
How Does Disease Spread in Poverty, and How is This Possible in Western Culture?

Components of slums:
Lack of clean water
no access to health care

U.S. metropolitan areas have large populations of “poor, usually disproportionately minority, households; households suffering from not just poverty, but from many attendant social problems”*

Outside of Western Poverty
Frequent person-to-person contact contributes to the communal spread of disease.
This may occur in:
Dense metropolitan areas
Disease Spread and Travel
Vaccination and Disease Spread
Vaccination is among the most significant public health success stories of all time, according to the Center for Disease Control and Prevention (CDC)*
Those without vaccination at increased risk.
If the non-vaccinated population is greater, vaccines will not be effective.
Those below the poverty threshold (e.g. the homeless) experience similar problems as slums, increasing disease vulnerability.
Infectious disease spread is
limited to the area in which it starts.
Mary E. Wilson, M.D. stated that “organisms that survive primarily or entirely in the human host and are spread through sexual contact, droplet nuclei, and close physical contact can be readily carried to any part of the world”*

Infections disease has been spreading across all socioeconomic levels since the thirteenth century.
The living conditions of a region plays a central factor in disease spread, however behavioral factors also must be considered.
With the knowledge of how disease spreads, successful efforts towards disease prevention can be made.
