miasmas "bad air or vapors" that people originally thought
caused contagious disease
Germ theory of Disease Evidence starts to build that microbes, rather than
sin or miasmas, cause contagious diseases
Ignaz Semmelweis (1840's) -Suspected that doctors were transmitting
childbed fever to women during childbirth
-Required hand washing in chlorine solution
-Incidence of childbed fever dropped from 50%
to 1%
-Was not believed and was ridiculed by other
doctors
,John Snow (1850's) -Cholera is a life-threatening diarrheal disease,
most people in the 1800's thought the cause was
bad air.
-Severe epidemics in London and other cities.
-Snow mapped distribution of cholera cases in
London: hoped to determine cause of outbreak.
John Snow's survey -He found that 500 fatal cases occurred in 10
days within 250 yards of a certain intersection.
-Conducted a survey:
-People got water fro the Broad Street pump =
people with cholera.
-People who got water from other sources but
lived in the same area were not sick at the same
rate.
-removed the handle of the pump and the
cholera epidemic was ended soon after.
Joseph Lister (1860's) - showed that microbes are everywhere including
air
- Linked microbes to food spoilage
- Demonstrated that heat treatment can kill
microbes (Pasteurization)
Louis Pasteur (1860's-1880's) -Suspected that microbes could cause disease
-Discovered that microbes too weak to cause
disease can be used to generate immunity.
, Robert Koch (1870's-1900's) - Provided solid supporting evidence for the
germ theory of disease by demonstrating that a
specific bacterial species caused anthrax in
animals.
- Developed techniques for growing bacteria in
the lab
- Proposed Koch's Postulates for determining the
causes of many infectious diseases.
- Discovered the bacterial causes for tuberculosis
and Cholera.
The great sanitary movement - Based on idea held by social reformers that
(1850's-1890's) many diseases could be prevented by removing
"filth"
-Human and animal waste
-Dead animals
-Garbage, etc
-Growing evidence that water sources and
sewage were tied to repeated cholera epidemics
finally led to sewer systems, water and sewage
treatment facilities in cities.
-Level of certain infectious diseases decreased
dramatically.
Results of the great sanitary -Massachusetts Board of Health founded as the
movement? country's first State Health Dept.
-Marine Hospital Service (later called U.S. Public
Health Service) given more powers
