UNIVERSAL PRECAUTIONS and PATHOGEN AWARENESS FOR
SCHOOLS
  • A Self Directed Learning Unit for RTMSD Employees

3
  • Exposure to disease causing viruses and bacteria
    can occur anywhere--even in schools

4
  • Disease-causing bacteria, viruses, and other
    microorganisms are called pathogens.

5
  • Although the risk of exposure to pathogens for a
    school employee is low, it is not zero.

6
  • For this reason, it is important to know
    about pathogens and how to protect yourself from
    diseases they can cause.

7
  • Where or how might a school employee be exposed
    to contagious pathogens?

8
Pathogens (germs) can be found on environmental
surfaces, in blood, and in other body fluids.
9
Blood borne pathogens are high profile
pathogens because of the serious nature of the
diseases they cause, but pathogens also exist in
other body fluids.
10
Body fluids with which a school employee might
come in contact include blood, vomitus, urine,
feces, saliva, and respiratory secretions.
11
  • The following slides identify some of the
    pathogens that may be found in various body
    fluids.

12
Urine
  • cytomegalovirus

13
Feces
  • Salmonella bacteria
  • Shigella bacteria
  • Rotavirus
  • Hepatitis A virus

14
Respiratory Secretions
  • Mononucleosis virus
  • Rhinovirus (common cold virus)
  • Influenza virus

15
Vomitus
  • Gastrointestinal viruses such as
  • Norwalk Virus
  • Rotavirus

16
Blood
  • Hepatitis B virus
  • Hepatitis C virus
  • Human Immunodeficiency Virus (HIV)
  • Cytomegalovirus

17
  • Three pathogens which may be transmitted in
    blood (blood borne pathogens) warrant further
    attention because of the serious nature of the
    diseases they cause. These three viruses are
  • Hepatitis B
  • Hepatitis C
  • HIV

18
  • Hepatitis B

19
Hepatitis B
  • Hepatitis means inflammation of the liver.

20
Hepatitis B
  • An individual can be exposed to Hepatitis B
    virus by coming in direct contact with
    contaminated blood or with blood-contaminated
    environmental surfaces.

21
Hepatitis B
  • Hepatitis B virus enters the body through a
    mucus membrane or a break in the skin.

22
Hepatitis B
  • When Hepatitis B virus enters the body, it
    travels to the liver and can cause life-long
    infection, cirrhosis of the liver, liver cancer,
    liver failure, and even death.

23
Hepatitis B
  • Hepatitis B virus can live outside the body for
    up to one week.

24
Hepatitis B
  • It is estimated that 1/3 of the worlds
    population including 5 of the US population are
    infected with Hepatitis B virus.

25
Hepatitis B
  • A vaccine called the Hepatitis B Virus (HBV)
    vaccine, which is a series of 3 immunizations,
    protects against the Hep B virus.

26
Hepatitis B
  • HBV vaccine is required for school entry for
    students in Pennsylvania. Check your immunization
    record or with your doctor to see if you have
    received this vaccine.

27
  • Hepatitis B
  • The vaccine is one important way to protect
    yourself against Hepatitis B.

28
  • Human Immunodeficiency Virus
  • (HIV)

29
HIV
  • Although HIV has gotten a lot of media
    attention, it is not as common a blood borne
    pathogen as Hepatitis B (HBV).

30
HIV
  • It is estimated that there are 40 million
    people living with HIV or AIDs worldwide, with
    about 1 million in the US.

31
HIV
  • The Human Immunodeficiency Virus (HIV) does not
    live long outside the body, and it is not an easy
    virus to pass from one person to another,
    however, the consequences of contracting HIV are
    so serious, that one must always protect oneself
    against possibly coming in contact with the virus.

32
HIV
  • HIV is transmitted through contaminated blood,
    semen, vaginal secretions, and breast milk.

33
HIV
  • Although the virus can be found in sweat,
    tears, vomit, saliva, feces, and urine, it has
    never been reported that it was ever transmitted
    in these fluids.

34
HIV
  • HIV invades and destroys the immune system and
    weakens cells that normally fight off infection,
    leaving the body unable to fight other diseases.

35
HIV
  • People who become infected with HIV may have no
    symptoms for up to 10 years, but they can still
    transmit the infection to others. Meanwhile,
    their immune system gradually weakens until they
    are diagnosed with AIDS.

36
HIV
  • HIV is a chronic medical condition that can be
    treated, but not cured. There are effective means
    of preventing complications and delaying, but not
    preventing, progression to AIDS. At the present
    time, not all persons infected with HIV have
    progressed to AIDS, but time has shown that the
    vast majority do.

37
  • Hepatitis C

38
Hepatitis C
  • Hepatitis C is less easily transmitted than
    Hepatitis B, but it is a more serious illness.

39
Hepatitis C
  • Hepatitis C can cause liver damage, cirrhosis,
    and cancer.

40
Hepatitis C
  • Hepatitis C virus can live up to a week outside
    the body.

41
Hepatitis C
  • It is estimated that about 4 million people in
    the US have been infected with Hepatitis C.

42
  • What can school employees do to protect
    themselves against these and other potentially
    dangerous pathogens?

43
  • School employees should follow these two
    important guidelines
  • 1) Practice good hand washing
  • 2) Use universal precautions

44
Guideline One
  • Practice Good Hand Washing

45
Why is hand washing so important?
  • Hand washing, when done correctly, is the
    single most effective way to prevent the spread
    of communicable diseases.

46
steps to good hand washing
  • Wet hands with warm running water.
  • Add soap.
  • Rub hands together away from the running water in
    order to form a lather.
  • Rub hands for at least 15 seconds.
  • Wash the front, back, fingers, and under nails.
  • Hold hands downward while rinsing under warm
    water so that the water does not run down arms.
  • Dry thoroughly with paper towel.
  • Turn off water with a towel and dispose of it
    properly.

47
  • Remember to rub your hands for at least 15
    seconds and form a lather with the soap.
  • (Time yourself by singing Row, Row, Row Your
    Boat, or Happy Birthday.)

48
Soap lather suspends dirt and germs so they can
be easily washed away.

49
  • If using alcohol based hand gel, use ½ to 1
    teaspoon in the palm of your hand.
  • Rub hands, covering all surfaces with sanitizer
    and let dry.

50
Alcohol based sanitizers should contain at
least 60 alcohol.


51
Guideline Two Use Universal Precautions
52
  • Universal precautions means treating ALL body
    fluids as if they are contaminated with pathogens.

53
This means wearing gloves when coming in
contact with any body fluid.

54
  • Skin is the first line of defense against
    pathogens but germs can enter through small cuts
    or tiny breaks in the skin.

55
  • Gloves act as a second line of defensea second
    barrierto keep pathogens from entering the body.

56
  • Your school nurse or supervisor can provide you
    with disposable gloves.

57
  • Any open cuts or sores should be covered with a
    band-aid or dressing before putting on gloves.

58
  • Never pick up sharp objects or broken glass
    with a gloved or bare hand.

59
  • Gloves are designed for single use only and
    should be replaced as soon as possible if there
    is a tear or defect.

60
  • It is important to remove gloves without
    touching the outside surface with your bare hands
    since the outside may be contaminated with
    pathogens.

61
To remove gloves, begin by grasping the cuff on
the outside surface with your other gloved hand.
62
Pull the glove toward fingers and off into the
other gloved hand.
63
Hold the glove you removed in the palm of your
gloved hand.
64
Remove the second glove by sliding your fingers
underneath the cuff to avoid touching the outside
surface with your bare hand.
65
Pull it off toward your fingers, removing the
glove completely.
66
With contaminated surfaces safely facing inward,
gloves are ready for disposal in the trash.
67
  • Always wash hands after removing gloves because
    gloves may contain flaws or defects that are not
    noticeable or you may have accidentally touched a
    contaminated part of the glove.

68
  • Be smart! Take the time to protect yourself
    with gloves before assisting a student or
    colleague who needs first aid.

69
  • Our school buses are supplied with spill
    kits. Bus drivers are trained to use the
    supplied products including gloves, absorbent
    agent, and cleaning tool, if there is a incident
    necessitating body fluid clean-up on the bus.

70
  • Do not attempt to clean up body fluids such as
    vomit or blood unless you have had special
    training.
  • Instead, call a custodian.

71
Our custodians have been trained in the clean-up
of body fluids and hazardous wastes and have
equipment and products appropriate for the job.

72
What should you do if you come in contact with
body fluids?
  • Wash hands immediately with warm water and soap
    for at least 15 seconds.
  • Follow district guidelines to report the exposure
    incident to your supervisor.

73
Review of Important Points
  • You can come in contact with pathogens
    anywhereeven in schools.
  • Protect yourself against pathogens by practicing
    good hand washing and universal precautions.
  • Universal precautions means treating all body
    fluids as if they were contaminated and wearing
    gloves if there is a chance of contact with body
    fluids or contaminated surfaces.
  • Universal precautions are an important way to
    protect yourself and others.

74
A safe school is a school where good hand washing
is practiced and universal precautions are
followed.

75
  • I have completed the self-paced learning unit
    entitled Universal Precautions and Pathogen
    Awareness for Schools.
  • I understand that if I have questions, I will
    contact my school nurse or supervisor.
