Infection Control Flashcards
Goal of Infection Control
Prevent the spread of infectious disease.
Infectious Disease
Any disease caused by the growth of pathogens in the body. Can cause unnecessary pain, suffering, and death.
Systemic Symptoms
Fever Headaches Fatigue Vomiting/diarrhea Increased heart rate and respiratory rate
Localized Symptoms
Redness
Swelling
Pain
Warmth
Chain of Infection
- Infectious agent
- Reservoir host
- Portal of exit
- Route of transmission
- Portal of entry
- Susceptible host
Reservoir Host
The pathogen must have a place to live and grow like a human body or contaminated food or fluids.
Portal of Exit
The pathogen must be able to escape from where it has been growing:
- Blood
- Urine and feces
- Breaks in the skin
- Wound drainage
- Body fluids- saliva, mucus, reproductive fluids
Route of Transmission
The pathogen leaves the reservoir through the portal of exit:
- Air
- Food
- Direct contact
- Insects
Portal of Entry
- Mouth
- Nostrils
- Breaks in the skin
Susceptible Host
Individual who has a large number of pathogens and does not have adequate resistance to the invading organism.
Breaking the Chain:
Infectious Agent
Early recognition of the infection and rapid and accurate identification of organisms.
Breaking the Chain:
Reservoir Host
- Medical asepsis
- Standard precautions
- Good employee health
- Environment sanitation
- Disinfectant/sterilization
Breaking the Chain:
Route of Transmission
- Hand washing
- Standard precautions
- Sterilization
- Medical asepsis
- Air flow control
- Food handling
- Transmission based precautions
Breaking the Chain:
Portal of Entry
- Wound care
- Catheter care
- Medical asepsis
- Standard precautions
Breaking the Chain:
Susceptible Host
Treating underlying disease and recognizing high-risk patients.
