Human Disease Prevention

What is Disease?
  • A disease is anything infectious (spreading from
    one organism to another) or noninfectious (does
    not spread from one organism to another) that
    changes or disrupts normal cell function.

3
History of Disease (Ancient Civilizations
Theories of Disease Causation)
  • Egyptian Medicine
  • The early Egyptians (4000-1000 B.C.) had many
    remedies for illness. Spells, incantations, and
    magic were integral parts of their medicine.
  • Among early races, illness and death were
    attributed to actions of the gods and demonic
    possession.

History of Disease (Ancient Civilizations
Theories of Disease Causation) cont
  • Egyptian Medicine cont
  • Despite their lack of scientific knowledge, some
    of the treatments they used were effective and
    still used today.
  • Egyptians are recognized as the first to treat
    disease systematically.

6
Greece The Teachings of Hippocrates
  • Hippocrates believed in the healing power of
    nature and thought that disease developed from
    natural causes.
  • Hippocrates prescribed diets, rest, fresh air,
    massage, and baths as treatments.
  • Hippocratess approach to disease and research
    were the first steps on the way to the prevention
    and control of disease.

7
The Immune System
  • The immune system is a complex protection
    mechanism that functions by protecting the body
    from harmful microorganisms (bacteria, viruses,
    fungi, and parasites) and foreign materials
    (toxins and venoms), while recognizing and
    eliminating foreign pathogens.

Lets Review!
  • True Or False
  • Americans were the first to systematically treat
    disease.
  • Hippocrates is one of the pioneers of disease
    prevention.
  • Bacteria can be cured but viruses cannot.
  • Define the following word/s
  • disease

10
The Immune System (Two Parts)
  • Innate
  • The bodys first line of defense against disease.
  • Skinouter protective barrier
  • Macrophages, Natural Killer Cells Neutrophils
    kill infectious agents
  • Adaptive
  • Second Line of defense
  • White blood cells Lymphocytes
  • Antibodies formed when there is a pathogen

Two Disease Categories
  • Infectious Disease (Chronic Acute)
  • Noninfectious Disease (Chronic Acute)


13
What is Infectious Disease?
  • A disease caused by organisms that enter the body
    and multiply within the human body.


14
What is Noninfectious Disease?
  • Diseases that are not transmitted by means of a
    pathogen (foreign invaders on in the human body).


15
Chronic Acute Disease
  • Chronic Disease A disease or health condition
    that lasts longer than three months, sometimes
    for the remainder of one's life.
  • Acute Disease A disease or health condition that
    occurs and subsides within three months, usually
    within days or weeks.

16
What Are Some Examples of Chronic Infectious
Diseases?
  • HIVvirus that attacks the immune system making
    it difficult to fight disease
  • TuberculosisBacterial infection of the lungs.
  • MeningitisInflammation of the membranes that
    cover the brain and spinal cord.
  • EncephalitisInflammation of the brain
  • Poliomyelitis (Polio)caused by a virus of the
    CNS
  • Others?

17
What are Some Examples of Acute Infectious
Diseases?
  • The cold viruscauses inflammation in the mucous
    membranes lining the nose and throat.
  • Influenzaa viral infection of the respiratory
    tract.
  • Mononucleosis Known as the kissing disease,
    common in teens its a virus that multiplies in
    the lymphocytes changing lymphocyte appearance.
  • Others?

18
What are Some Examples of Chronic Noninfectious
Diseases?
  • Diabetes
  • Osteoporosis
  • Arthritis
  • Heart (cardiovascular) Disease
  • Cancer
  • Hypertension
  • Others?

19
What are Some Examples of Acute Noninfectious
Diseases (This is a hard one)?
  • Heart Attack
  • Stroke
  • Cardiac Arrest
  • HypoglycemiaToo low blood sugar levels
  • HyperglycemiaToo high blood sugar levels
  • Others?

20
Lets Review!
  • Define the following
  • Infectious Disease
  • Noninfectious Disease
  • Chronic Disease
  • Acute Disease
  • Acute Infectious Disease
  • Name two
  • Acute Non Infectious Disease
  • Name two
  • Chronic Infectious Disease
  • Name Two
  • Chronic Non Infectious Disease
  • Name Two

21
Disease Prevention (infectious and noninfectious)
  • Three ways/methods of disease prevention
  • Primary Prevention
  • Secondary Prevention
  • Tertiary Prevention

22
Primary Prevention (infectious disease)
  • Primary PreventionPrevention measures before the
    disease happens.
  • Methods of Primary Prevention
  • Seclusion or avoidancestaying away from infected
    individuals
  • Keeping yourself cleanwash hands with
    antibacterial soaps shower
  • Get enough rest
  • Exercise on a regular basis
  • Eat Right

23
Primary Prevention (noninfectious disease)
  • Prevention measures before the disease occurs.
  • Methods
  • Not Smoking or drinking in excess
  • Eating right
  • Exercise on a regular basis

34
Tertiary Prevention
  • Tertiary PreventionMeasures aimed at
    rehabilitation following significant disease.
  • Methods

35
ScenariosWhats the Level of prevention?
  • Wanda stays at home all day in fear that she will
    catch a disease. She is always in the restroom
    washing her hands and when someone sneezes, she

    chance of survival without medication and
    surgery. Hector had the surgery but eventually

  • If you said tertiary(congratulations!) you are
    correct!!!

37
ScenariosWhats the Level of prevention?
  • Eric visits his doctor on a regular basis because
    he is a hypochondriac (his preoccupation with
