This document discusses the development of theories of disease and infection from the 17th century to present day. It describes how early doctors like Edward Jenner developed the first vaccine for smallpox. Later, Louis Pasteur identified microorganisms as the cause of infectious diseases. Joseph Lister then developed sterilization techniques to prevent surgical infections. Modern research has also linked nutrition to disease, like scurvy being caused by a lack of vitamin C.

1. Developing a Theory for Disease
Mr. Ilko

2. How is this Important?
 Have you ever broken a bone?
 Scraped your body badly?
 Cut yourself with a knife and needed stitches?
 Consider yourself lucky to be alive!!
 200 years ago you most likely have died from
infection based on any of these injuries
 50% of wounds caused death through infection

4. Vaccinations
 During the 1600 and 1700’s, people of Europe
and the rest of the world were suffering and dying
from a disease called small pox.
 Up to 40% of all who contracted it died, most
survivors were left blind
 A man named Edward Jenner, an English country
doctor, noticed that milkmaids who got cowpox,
never got small pox
 He discovered that if injected with cowpox, you
were immune to small pox
 This created the world’s first vaccine

6. The Germs Among Us
 What caused disease and infection?
 It wasn’t until a French chemist named Louis
Pasteur identified micro-organisms as “germs”.
 This understanding lead him to discover and cure
many common but deadly diseases

8. Cleaning up the Germs
 Thanks to Pastuers discoveries in medicine we
have made several advancements in
understanding and preventing infections
 An example of this was Joseph Lister, an English
Surgeon who figured out that micro-organisms
were infecting his patients after surgery
 He Created the practice of sterilization and
cleanliness of medical procedures
 Before Lister, nurses and doctors never thought
of taking care of their patients or their own cuts

10. Be Cautious About Vaccines!!!!
 This is a slide about being cautious about what
you have done to yourself.
 Many people in the world are over vaccinated,
this means that people are taking vaccines for no
reason year after year.
 These people are at risk of getting sick because
their body is not producing their own antibodies to
fight disease, they are relying on the vaccines

11. Don’t believe Me??
 Measles death rates in both the United States
and Great Britain fell more than 90% twenty years
before the measles vaccine program was initiated
in 1960.
 Pertussis death rates fell more than 80% prior to
when the pertussis vaccine was made mandatory
 These drops were responsible for the cities
improvement of sanitation and overall cleanliness

12. A Doctor to Hear From?

 This is a doctor who briefly goes into why
vaccinations can be dangerous if used at the
wrong time in life – Full clip is 1.5 hours

13. Extreme Cases
 There are instances where doctors have
vaccinated children against the will of their
parents
 After these doctor approved vaccinations some
children have come out with cases of Autism or
sicknesses
 Many vaccinations contain mercury or a
contaminated form of the disease, which has
made children sick and have died because of
this.
 My Warning: Think for yourself, don’t just rely on
everything to help you. Be Clean, Be Smart.

15. Nutritional Research
 These kinds of discoveries are not only limited to
the medical field
 There have been numerous advancements in the
area of nutrition just because we understand how
micro-organisms influence and effect us each
day.
 By studying various diseases such as heart and
liver disease, researchers have determined that
diet affects the human body as well.

16. Scurvy
 During the 1700’s early sailors went on voyages
to find the Northwest Passage, and they could
only bring with them food that wouldn’t spoil
 Salt beef, hard bread, dried peas, and cheese
 After months at seas, many sailor developed
scurvy
 Finally in 1747, James Lind, a naval surgeon
treated scurvy by feeding the sailors oranges and
lemons
 A lack of vitamin C lead to scurvy

18. Nutrition
 Too much of some foods, and too little of others
can interfere with proper functioning of the bodies
systems.
 People have developed the Canada Food Guide
to assist people in making the proper food
decisions and create balance to their diets.
