Infection prevention Control
What are the 6 “links” in the chain of infection?
1- infectious Agent /causative Agent
2- Reservoir
3- portal of exit
4- mode of transmission
5- portal of entry
6- susceptible host
Infection prevention Control
What is an infectious agent?
Tip: causative agent
A microorganism capable of causing disease to humans
Infection prevention Control
What are the 4 main Infectious agents ?
Viruses (often there are vaccines for these)
Bacteria
Fungi
Parasite
Infection prevention Control
HIV, chicken pox, influenza, hepatitis are examples of what type of Infectious agent?
VIRUSES
this agents are the smallest and made up of DNA and RNA
Infection prevention Control
Pulmonary tuberculosis, streptococci ( strep throat) are examples of what type of Infectious agent ?
tip. Treated with antibiotics
BACTERIA
this agent is a single cell / reproduces rapidly
Infection prevention Control
How do bacteria a viruses reproduce and what is the difference?
|tip. Viruses are made of DNA and RNA and bacteria is a Cell!
Bacteria can reproduce itself
Viruses require a living host to reproduce ( must invade other cells to reproduce)
Infection prevention Control
Can bacteria survive without a host ?
Yes
Infection prevention Control
Can a virus survive without a host ?
No
Infection prevention control
Ringworm is an example of what type of Infectious agent?
FINGUI
single or multicelled / on skin but can invade deeper
Infection prevention control
Lice is an example of what type of Infectious agent?
PARASITE
|live on host and at the expense of its host
Infection prevention Control
What is a reservoir?
second on chain of infection
Where organism LIVES and GROWS between outbreaks.
Where germs live and thrive !
Infection prevention Control
What are examples of reservoirs?
People
Fomites (equipment, materials, doorknobs, table tops)
Vectors
Food
Soil, water
Feces
Infection prevention Control
What measures can you take to break the reservoir “link” of the chain ?
• wash hands
•clean, disinfect or sterilize environment and materials
Infection prevention Control
What measures can you take to break the Infectious agent “link” of the chain ?
•Chose the right cleaning products to kill pathogen
•seek medical help
Infection prevention Control
What is a Portal of exit?
third on chain of infection
Identifies how the infectious agent can leave the reservoir
How germs get out!
Infection prevention Control
What are examples of portals of exit?
Blood
Body fluids ( saliva, vomit)
Poop
Skin
By coughs and sneezes
Infection prevention Control
What measures can you take to break the portal of exits “link” of the chain ?
•wash hands
•PPE
•Properly disposal of trash
•covering your mouth when sneezing or coughing
Infection prevention Control
What is Mode of transmission?
fourth on chain of infection
Transmission identifies how an organism moves from one host to another host
How germs get around!
Infection prevention Control/Mode of transmission
What are the 4 main routes of transmission in an acupuncture clinic ?
- direct contact
- indirect contact
- droplets
- Airborn
Infection prevention Control/Mode of transmission
What is a vector?
living organism that transmits an infectious agent from an infected animal to a human or another animal
Examples: mosquito, fly, lies
Infection prevention Control/Mode of transmission
What are fomites ?
Tip: reservoirs in the chain of infection
objects or materials which are likely to carry infection, such as clothes, utensils, and furniture
inanimate objects
Infection prevention Control/Mode of transmission
What is DIRECT contact transmission?
Transmission by direct physical contact btwn. infected person and vulnerable person.
|human to human transmission
Infection prevention Control/Mode of transmission
Name an illness that can be transmitted by direct contact transmission?
Gastrointestinal infection
Infection prevention Control/Mode of transmission
What is INDIRECT contact transmission?
Transmission through an intermediary
|No direct human to human transmission
