Bloodborne Pathogens
•
Bloodborne Pathogens
are microorganisms
(such as viruses)
transmitted through
blood, or other
potentially infectious
material such as certain
bodily fluids (semen,
breast milk, etc.) or
tissues.
{
Bloodborne Pathogens
•
Bodily fluids, especially those
visibly contaminated with
blood, are capable of causing
disease.
•
Pathogens can enter your
body through a cut in the
skin, through your eyes or
mouth.
{
•
Can also be transmitted
sexually
•
Main diseases of concern are
Hepatitis B (and C) virus, and
HIV (AIDS virus).
Human Immunodeficiency Virus (HIV)
•
•
{
•
HIV attacks your body’s
ability to protect itself
against disease
Initially no visible signs of
having the virus
Most people with HIV
develop AIDS (acquired
immune deficiency syndrome)
•
There is no vaccination
for HIV
HIV
•
•
Virus lives outside the body only
a few hours
4 modes of transfer:
 blood
 semen
 vaginal secretions
 breast milk
{
HIV
10-50 virus particles per ml of blood

Hepatitis B Virus
{
Hepatitis B (and C)
•
Up to 100 times
easier to catch
than HIV
•
Unlike HIV, can
live outside of
body for several
days
Concentration of Hepatitis B Virus in
Various Body Fluids
{
Hepatitis B
{
•
•
1,000,000 - 1,000,000,000 virus particles per ml
of blood
Virus can live outside the body for several days
HIV vs. Hepatitis B
{
Hepatitis C
•
•
•
•
3-4 million carriers
Disease can
incubate for
decades
By 2010 may affect
more Americans
each year than AIDS
HCV not related to
the viruses that
cause HBA and HBV
{
Hepatitis C
{
Hepatitis C
•
Risk Factors:
Long-term kidney
dialysis
o Sex with multiple
partners
o Tattooing or body
piercing with shared
needles or unsterilized
equipment
o Intranasal cocaine use
with shared straws

Pamela Anderson claims her infection
came from a tattoo needle
Hepatitis B (and C)
•
There is no cure for Hepatitis B
or C…
•
but unlike HIV, there is a
vaccination for Hepatitis B.
{
(There is no vaccination for Hepatitis
C)
HBV and HCV
•
Liver is located
behind the lower ribs
on the right side of
your abdomen
•
Weighs about 3
pounds and is roughly
the size of a football.
{
•
If infected with HBV,
the liver often
becomes tender and
enlarged
Some signs and symptoms of HBV
and HBC include:
•
•
•
•
•
•
•
•
Flu-like symptoms
normal
fatigue
jaundice
severe pain in joints
lung disease
inflammation of liver
inflammation on and ulcers of the colon
may be asymptomatic (i.e. no symptoms indicated)
Yellow

jaundice
Hepatitis
Acute: 6-8 weeks, 90%
•
•
30-40% with acute HBV have no idea how or when they
became infected
5-15% of infected carry virus for longer than 6 months
(carriers)
Chronic:
{ Life, 10%
•
•
Hepatitis B carriers are people infected with HBV and
never fully recover. They carry the virus and can infect
others for the rest of their lives
Approximately one million people in the US carry HBV
Acute Viral Hepatitis by Type
{
Risk Factors for Acute Hepatitis B
{
Hepatitis B
•
•
“The risk of contracting Hepatitis B
from a single needlestick
contaminated with blood from a
person with known Hepatitis B
ranges from 6% to 30%.”
“Approximately 10% of those
infected become chronic carriers
who can infect their families and
friends. They have up to 300 times
greater than normal risk of
developing liver cancer.”
{
•
“Every year, approximately 5,000
Americans, die of HBV or its
complications.
Part 2
Statistics from Milwaukee
Journal/Sentinel
•
{
“…1 in 300
infected with HIV”
Milwaukee Journal/Sentinel, July 7,
1996
•
“one in 20 people has
or has had Hepatitis”
How Bloodborne Pathogens Spread
on the Job
• When a contaminated object touches inflamed
skin, acne, skin abrasions
•
When you
touch a
contaminated
surface and
then touch
your eyes,
nose, mouth,
or open
wounds or
inflamed skin
{
