Definitions (From OSHA)
• Bloodborne Pathogen- microorganisms that are
present in human blood and can cause disease in
humans
• Exposure Incident- specific eye, mouth, mucous
membrane, non-intact skin or parenteral contact
with blood or OPIM that results from the
performance of a member’s duties
• Parenteral- piercing mucous membranes or the
skin barrier through such events as needle sticks,
human bites, cuts, and abrasions

Definitions (Continued)
• Personal Protective Equipment (PPE)- specialized
clothing or equipment worn by a member for protection
against a hazard. General work clothes (uniforms,
jumpsuits, etc.) not intended to function as protection
against a hazard are not PPE.
• Universal Precautions- an approach to infection control
where all human blood and certain human body fluids are
treated as if known to be infectious
• Body Substance Isolation (BSI)- a form of infection
control based on the presumption that all body fluids are
infectious. BSI calls for always using appropriate barriers to
infection at an emergency scene, such as gloves, goggles,
face shields, gowns, and protective eyewear.

secretions, CSF, synovial fluid, pleural, pericardial,
peritoneal, amniotic, saliva (dental procedures), any
bodily fluids contaminated with blood, any fluid that
cannot be differentiated between fluid types.
• Any unfixed tissue or organ from a human (living or
dead)

Two Major Definitions
• Infectious
– An illness that is caused by the body's
rejection of a virus, fungi, or parasite
• Communicable
– Able to spread from one person to another
A disease can be infectious and
not communicable at the same time

![Page 21: Bloodborne Pathogens and Communicable Diseases 2012cmtems.com/quiz/tests/Bloodborne.Pathogens.2012.pdf · 4 Definitions (From OSHA) • Bloodborne Pathogen- microorganisms that are](https://reader036.vdocuments.us/reader036/viewer/2022062414/5f0d77dc7e708231d43a818d/html5/thumbnails/21.jpg)
21
Modes of Transmission
• Direct contact – straight from person to person, exchange of blood or body fluids
ex: blood splash into the eyes
• Indirect contact – person to object; infection can spread by touching surfaces that have been contaminated with the bacteria or virus
ex: Loading stretcher into ambulance and not removing contaminated gloves before touching steering wheel of ambulance
touching a contaminated needle
![Page 22: Bloodborne Pathogens and Communicable Diseases 2012cmtems.com/quiz/tests/Bloodborne.Pathogens.2012.pdf · 4 Definitions (From OSHA) • Bloodborne Pathogen- microorganisms that are](https://reader036.vdocuments.us/reader036/viewer/2022062414/5f0d77dc7e708231d43a818d/html5/thumbnails/22.jpg)
22
Direct Contact
• Bloodborne
• Airborne
• Occult
– Occult means “hidden”
– “Occult blood” is blood hidden inside
some other material
• Idiopathic
– Fancy medical word meaning “We
don’t have a clue!”
![Page 23: Bloodborne Pathogens and Communicable Diseases 2012cmtems.com/quiz/tests/Bloodborne.Pathogens.2012.pdf · 4 Definitions (From OSHA) • Bloodborne Pathogen- microorganisms that are](https://reader036.vdocuments.us/reader036/viewer/2022062414/5f0d77dc7e708231d43a818d/html5/thumbnails/23.jpg)
23
Indirect Transmission
• Vehicle-borne
– The transfer of an infectious agent to a
host via contaminated items such as
water, food, milk, or biological
products, such as blood, tissues, and
organs.
• Vector-borne
– The transfer of infectious
microorganisms from an infected host
via an insect or arthropod.

24
Methods to Reduce Exposure
• Engineering Controls
– Devices that may be used to eliminate,
minimize, or reduce occupational
exposure to bloodborne pathogens.
• Work Practice Controls
– Practices and procedures that reduce or
eliminate the chance of occupational
exposure to bloodborne pathogens.

container. No one is to remove anything
from a sharps container. Sharps containers
are located on the ambulance and ALS
Bag.

HIV/AIDS
• Human Immunodeficiency Virus
• HIV is the virus that causes Acquired

HIV/AIDS
• Antibodies are formed six to twelve (6-12)
weeks after infection. The AIDS test looks
for these antibodies, not the virus itself
• No anti-virus, no vaccine and no cure
• There are a SMALL NUMBER of
healthcare providers who have contracted
HIV infection through their duties as
compared to HBV

Contracting HBV and HIV
• Neither of these viruses are airborne. You
cannot catch them through routine contact
• You can contract the virus if
• You suffer a needle stick from an infected sharp
(0.4% for HIV, 6-30% for HBV)
• Infected material comes in contact with your broken
or non-intact skin (chapped, abrased, etc.)
• Infected material comes in contact with your
mucous membranes of the eyes, nose, and mouth

Hepatitis-C
• Unrelated to Hepatitis B
• Viral disease
• Transmitted by blood, needle stick, and sex
• WILL BEGIN WITH SAME
SYMPTOMS AS HEPATITIS B
• Only 25 % of infected individuals will
show signs or symptoms

Hepatitis-C
• Incubation period is up to 200 days

care workers
• NO CURE AT THIS TIME

– preventive measures used
• Filter Mask
• Double mask, caregiver and patient

TB (Con’t)
• INH is the drug used to prevent
disease development
• Multi-drug resistant TB can develop
– has been identified in up to 20 states
– Occurs when a patient fails to take all of
their recommended drug regimen
– LIFE EXPECTANCY IS ONLY 16
WEEKS AFTER CONTRACTING

Meningitis
• Inflammation of the protective membranes
covering the brain and spinal cord, known
collectively as the meninges.
• May be caused by infection with viruses,
bacteria, or other microorganisms.
• Can be life-threatening because of the
inflammation's proximity to the brain and
spinal cord; therefore the condition is
classified as a medical emergency.[1][3]

52
Meningitis
• Signs and Symptoms – Headache and neck stiffness associated with fever
– Confusion or altered level of consciousness
– Vomiting
– Inability to tolerate light (photophobia) or loud noises
(phonophobia)
– Sometimes, especially in small children, only
nonspecific symptoms may be present, such as
irritability and drowsiness.
– If a rash is present, it may indicate a particular cause of
meningitis; for instance, meningitis caused by
meningococcal bacteria may be accompanied by a
characteristic rash.[

Meningitis
• Modes of transmission
– Direct contact with respiratory
secretions
– Physical skin contact
• Treatment only available for
bacterial, but not viral

54
Determining a True Exposure
• Two questions will determine whether or
not an exposure has occurred: – Is the fluid I came in contact with blood, semen,
vaginal secretions, or any other body fluid containing
blood?
– Did the fluid enter my body by a needle-stick, non-
intact skin, laceration from a contaminated object,
through my eyes, nose, or mouth?
• Both answers must be yes in order for an
exposure to have occurred

care or ER.

Post Exposure Evaluation
• Available to all exposed members
• Confidential medical evaluation
• Incident Report filed as soon as possible
after exposure
• May include
– Several office visits
– Re-vaccination
– Prophylactic medications
