miasmas "bad air or vapors" that people originally
thought caused contagious disease
Germ theory of Evidence starts to build that microbes,
Disease rather than sin or miasmas, cause
contagious diseases
-Suspected that doctors were transmitting
childbed fever to women during childbirth
Ignaz Semmelweis -Required hand washing in chlorine solution
(1840's) -Incidence of childbed fever dropped from 50%
to 1%
-Was not believed and was ridiculed by other
doctors
-Cholera is a life-threatening diarrheal
disease, most people in the 1800's
John Snow (1850'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.
-He found that 500 fatal cases occurred in
10 days within 250 yards of a certain
intersection.
-Conducted a survey:
John Snow's 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.
- showed that microbes are everywhere including
Joseph Lister (1860's) air
- Linked microbes to food spoilage
- Demonstrated that heat treatment can kill
microbes (Pasteurization)
-Suspected that microbes could cause disease
Louis Pasteur (1860's- -Discovered that microbes too weak to
1880's) cause disease can be used to generate
immunity.
- Provided solid supporting

evidence for the germ theory of
Robert Koch (1870's- disease by demonstrating that a
1900's) 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.
- Based on idea held by social reformers
that many diseases could be prevented
by removing "filth"
-Human and animal waste
The great sanitary -Dead animals
movement (1850's- -Garbage, etc
1890's) -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.

sanitary movement? country's first State Health Dept.

cure many infectious diseases
-Development of drugs and medical
procedures to treat and sometimes cure
Progress since 1900 non- infectious diseases
-Development of numerous vaccines for
prevention of infectious diseases
-Better understanding of necessary nutrients
-Better understanding of the immune system
and other aspects of physiology
-Better care for pregnant women & newborns
-Contraception/Ability to control family size
-Understanding of certain diseases at
molecular/cellular level
-Disruption of a tissue or organ caused by
microbes or microbial products.
Infectious disease -Also includes diseases caused by larger
(non-microbial) parasitic organisms such
as worms, insects, and mites
-Most infectious diseases are communicable
