2- The Well-Being of the Emergency Medical Responder Flashcards
Preventing disease transmission:
1) How infections occur
2) How diseases spread from one person to another
3) What you can do to protect yourself and others
How infection occurs:
1) Pathogen gets into the body
2) Sometimes overpower body’s natural defense systems and cause illness
What causes most infectious diseases?
Bacteria and viruses

Yeasts
Candidaisis (aka “thrush”)
The Body’s Natural Defenses:
1) Intact skin & mucous membranes (keep germs out)
2) Immune system (antibodies and white blood cells)
Mild to serious and brief =
Long lasting=
acute
chronic
Signals that the body is fighting infection
Fever, exhaustion
headache, nausea and vomiting
CRITICAL FACT
Intact skin, as well as mucous membranes in the mouth, nose and eyes, are part of the body’s natural defenses to help keep germs out.
Three different types of human immunity:
1) Inate (born with, natural barriers like skin)
2) Adaptive immunity (develops throughout our lives as we are exposed to diseases or are immunized against them)
3) Passive immunity (gained from external sources such as from a mother’s breast milk to an infant)
How diseases spread:
Exposure to blood or body fluids through injuries from needles and other sharps devises, as well as by direct and indirect contact with skin and mucous membranes.
Four conditions must be met for any disease to spread:
1) Present
2) Quantity
3) Susceptible
4) Entry site
