Introduction to Infection control and asepsis
Our bodies are amazing structures that defend us against infections under normal circumstances
You will learn:
About disease causing microorganisms
How the body fights against disease
Ways infections occur
History of infectious disease prevention
Hippocrates - first after to prevent infection. He believed:
Environment and natural forces play an important part in role of disease and health
Simple treatments, using strong drugs and surgery only as a last resort
Joseph Lister
Discovered how to use chemical antiseptics to control surgery related related infections
Used antiseptics to disinfect surgical equipment and supplies
Microorganisms are simple forms of life commonly made up of a single cell only screen with a
microscope
Holmes and Semmelweis
Oliver Holmes
Demonstrated that puerperal fever was carried from Patrice to to patient by doctors
Ignacio Philipp Semmelweis
Told doctors to wash their hands
A slow concluded puerperal fever was a communicable disease
Microorganisms
Living cells
Found everywhere in the environment
Can be beneficial
Mold for cheese
Microorganisms
Can be harmful
, HIV causes AIDS
Understanding disease transmission helps create technology for disease prevention
You will care for patients with:
Infectious diseases
Communicable diseases
Microorganism -type
Virus- smallest infectious agent
Bacteria- single called reproduced quickly
Fungi- complex cell structure ( most do not cause disease)
Parasites- cause disease
Body’s Defenses
Immunity- resistant to pathogens and the disease they cause
If defensed are not functioning properly, person will become susceptible to invasion and infection
Lines of Defense
Skin
Normal flora
Specific Defense Against Disease
Immunity
Protects the body against very specific pathogens
Lymphocytes and macrophages are the major cells
Antibodies are the major proteins involved with n specific defenses
Chain of Infection
Has six sequentially steps
Used to prevent
infections or control infections by breaking one or more links in the chain
Can only occur when all six steps are intact
Breaks in the chain will decrease the likelihood of then disease being spread
infectious Agent
The name of the microorganism (bacteria, virus)
E.g. HIV, MRS Pathogen
Step 2 Reservoir
The source where the pathogens lives, grows, and replicates (multiples)
Humans
