Chain of infection
The germ that causes the disease
Infectious Agent
skin to skin contact
Direct contact
What is the main type of Precaution
Standard Precautions
What are Pathogens?
any organism or agent that causes disease in its host, such as humans, animals, or plants
The person at risk of infection which is usally people with weak immune system (elderly or children)
Susceptible Host
The place where the pathogen lives and multiplies
Reservoir
Touching contaminated surfaces or objects
Indirect Contact
Examples of standard precautions
Hand washing and PPE (Personal Protective equipment)
How many types of Pathogens are there?
Three
What is donning?
Putting on the PPE
The pathway the pathogen uses to leave the reservoir
Portal of exit
Most common way for droplet
Inhaling droplet from sneezes, coughs or breathing particles that may be in the air.
Why are standard precautions needed?
To avoid transmission of diseases
Organisms that live in or on a host, surviving by taking nutrients from the host.
Parasites
What does PPE stand for?
Personal Protective equipment
The pathogen moves from one host to another, this can be caused by direct contact, droplet (coughing), indirect contact (contaminated surfaces)
Mode of Transmission
What are the main three transmissions?
-Direct contact
-Droplet
-Airborne
Who do we use standard precautions for?
All patients, at all times
They have many cells and are plant-like organisms.
Fungi
What is doffing?
Taking PPE off
The way the pathogen enters a new host
Portal of Entry
Inhaling droplets from sneezes/coughs or breathing in particles that hang in the air.
Droplet and Airborne
True or False:
Standard precautions should only be used on patients who look sick
False: Standard precautions are used on every patient at all times
live inside living cells and spread diseases like chickenpox
Viruses
How many methods of transmissions are there?
Three
