|
Infectious Agent
|
|

|
Cause Disease and Infection
|
|
|

Helps minimize the the spread of health care associated infections
|
|

What is a Reservoir?
|
Where a pathogen can grow
Example: Soiled of wet dressing, dirty equipment |
|
|
Exit Route
|
Point of Escape from Reservoir
Example: Wounds, respiratory |
|
|
Carrier or Vector
|
A person or animal that does not become ill but harbors and spreads disease
|
|
|
Vehicle
|
method in which microorganisims are transported to the next host.
|
|
|
Contamination

Exposed to harmful agents
|
|
|
Vector
|
Living Carrier Vehicle
|
|
|
Formite
|
Vehicle of a NonLiving Object

|
Indirect Transmission
|
Transmission of disease through common contact
Example: A Person that gets sick because they drank out of the same glass as a sick person |
|
|
Direct Transmission
|
Transmission of disease through Direct contact
Example: If you dont wash your hands after treating bed A, then bathe the patient in Bed B. |
|
|
Entrance Of Microorganisims
|
Skin is the first line of defense.
Keep skin intact, lubricated, and clean |
|
|
Host
|
A organisim in which another organisim is nurished or harbored
|
|
|
Susceptibility to an infection
|
defined by the amount of resistance shown to the pathogen.
*** There is strength in numbers. As the pathogen's strength and numbers increase, the pts become MORE susceptiable. |
|
|
Factors that affect Immunity Defense
|
Age
Stress Nutrition Hereditary Environmental Lifestyle Tavel Trauma |
|
|
Localized Infections
|
Superficial wound contaned in one area
|
|
|
Systemic Infection
|
Infection that affects the whole body or a single organ
Example: HIV |
|
|
Stages of Infectious Process
|
Incubation Period
Prodromal Stage Illness Stage Convalescence |
|
|
Incubation Period
|
Entrance of the pathogen to signs of the 1st symptom
Example: Chicken Pox 1 to 3 weeks Common Cold 1 to 2 Days Influenza 1 to 3 days Mumps 12 to 26 days |
|
|
Procromal Stage
|
Interval between onset of signs and symptoms to time where more specific symptoms show.
VERY CONTAGiOUS |
|
|
Illness Stage
|
Manifests Signs/Symptoms specific to the type of infection.
Example: COmmon Cold is manifested by sore throat or sinus congestion |
|
|
Convalescence
|
Symptoms begin to disappear
Recovery Period |
|
|
