Well-Being of the EMT-Basic Part 2
Introduction to
Infectious Disease Control &
Prevention
Methods of Transmission
• Bloodborne
– Blood
– O.P.I.M. (other Potentially Infectious
Materials)
• Airborne
• Fecal-Oral
Infectious Disease Control & Prevention

Bloodborne Transmission
• Blood
• Body fluids visibly contaminated with
blood
• Body Fluids (visibly contaminated or not)
– Saliva, semen, vaginal secretions
– Cerebrospinal fluid, synovial fluid
– Amniotic fluid
• Unfixed organs or tissues
Infectious Disease Control & Prevention

Bloodborne Transmission
INJECTION
– Needle sticks, broken glass, sharp objects
OTHER DIRECT CONTACT
– Splashing of fluids into open cut or sore;
mucous membranes of eyes, nose, mouth
INDIRECT CONTACT
– Touching a contaminated object/surface, then
touching mouth, eyes, nose, open wound
Infectious Disease Control & Prevention

Airborne Transmission
• Aerosolized droplets spread into the air
when patient…

–
Coughs
Speaks
Gags or vomits
Is suctioned
Sneezes
Infectious Disease Control & Prevention
5
Fecal-Oral Transmission
• Results from improper
hand washing/hygiene
– After a bowel movement,
bacteria is transmitted to
food or objects via the
hands.

Does contact with BIOHAZARD material always
lead to infection?
CONTAMINATION
EXPOSURE
INFECTION
How old is pathogen?
How extensive is
contamination?
Length & route of exposure…
How quick was
decontamination?
Severity of exposure…
Virulence of pathogen…
Health of EMT…
Prophylactic drugs…

Disease Transmission Facts
INFECTIOUS HEPATITIS
– Hepatitis B…bloodborne
• Swelling, soreness, loss of function of the liver.
• Viral syndrome (weakness, fatigue, malaise, fever,
headache, anorexia, nausea)
• Abdominal pain
• Jaundice
• Or… No symptoms at all (chronic carrier state)
– 85% of patients recover in 6-8 weeks
– Will always carry virus once infected

Disease Transmission Facts
HUMAN IMMUNODEFICIENCY VIRUS (HIV)
– Affects white blood cells of the immune systems and
renders them ineffective in preventing disease.
– Illness & death occurs from Opportunistic Infections
such as pneumonia.
– Causes Acquired Immune Deficiency syndrome (AIDS)
– Initial symptoms are non-specific
• Viral syndrome
• Night sweats, weight loss
• Gland, muscle, & joint pain

Disease Transmission Facts
HUMAN IMMUNODEFICIENCY VIRUS (HIV)
• Bloodborne transmission.
• May take up to a year for virus to show up in a
routine HIV blood test.
• Patient may have no symptoms for many years,
resulting in inadvertent transmission to multiple
sex partners.
Infectious Disease Control & Prevention
10
Disease Transmission Facts
TUBERCULOSIS
– Airborn, spread by droplets
– Pulmonary infection with symptoms
developing within 2-10 weeks.
– Causes areas of “scar tissue” to develop in
lungs, leading to loss of pulmonary function.
Infectious Disease Control & Prevention
11
Disease Transmission Facts
Suspect T.B. when…
– Crowded living conditions (jails, military)
– Has close relative with active T.B.
– Person who:
•
•
•
•
Has HIV
On immunosuppressive drugs
Prolonged steroid therapy
IV drug users
– Recently had positive TB skin test.
Infectious Disease Control & Prevention
12
Disease Transmission Facts
Suspect T.B. when…
– Undiagnosed pulmonary or respiratory
infection
– Viral syndrome, night sweats, weight loss
– Productive cough (green or yellow sputum)
– Coughing up blood
– Difficulty breathing
– Respiratory failure

Prevention
• Frequent employee
education
• Hazard Communication
• PPE
• Labeling all infectious
waste
• Frequent hand washing
• Cleaning equipment
between patients
Infectious Disease Control & Prevention
Biohazard Label
16
Prevention
Latex or vinyl gloves…
The minimum PPE
for every patient
contact.
Infectious Disease Control & Prevention
17
Prevention
For splash hazards and
large amounts of
fluids…
– Eye protection
– Face mask
– Gown, apron, or
turnout gear
– Shoe covers
Infectious Disease Control & Prevention
18
Prevention
Highly infectious
respiratory diseases…
– Tuberculosis
– Meningitis
HEPA (high-efficiency
particulate)
respirator
Infectious Disease Control & Prevention
19
Prevention
Disinfect equipment
between patients…
– Reusable PPE is
permitted
– Dilute bleach
solution, or
commercial
disinfectant

Prevention—in advance
• Verify immune status
• Hepatitis B Vaccination (series of 3 shots,
and titer)
• Varicella immunity?
• Tuberculin Purified Protein Derivative
(PPD) skin testing (at least annually)
