What is infection control
controlling the spread of infection
What are fomites
any substance or object that adhears to and transmits infectious matirial
What is the number 1 way to prevent the spread of infection?
Hand clensing
WHO 5 minutes of hand washing
- Before touching a patient
- Before a clean (aseptic) procedure
- after body fluid exposure or risk of exposure
- after touching a patient
- after touching a patient’s surroundings
What is a standard precaution
Assume every patient is infected
What is a pathogen
germs
-literally means disease beginning
What are the 4 types of pathogens
Bacteria
Virus
Parasites
Fungi
What is bacteria
one celled microorganisms that are classified by shape
only killed by antibiotics
What is normal flora
helpful bacteria
nonpathogen
What are viruses
- smallest type of microorganism
- made of only a few molecules
- invade host cells where they take nutrients required to multiply
What are parasites
- organisms that live on or in an organism of a diffrent species
- treated with antiparasitics
What are fungi
plant-like microorganisms thatcan be found in the air, in soil, on plants, or in water.
- millions of types
- treated with antifungal
endogenous infection
caused by microorganisms present in the human body
exogenous infection
caused by microorganism, or pathogen, entering the humen body from the outside enviroment
Nosocomial infections
aquired by a person while in a healthcare setting
also known as HAI’s
oppertunistic infections
occur when the body’s defences are weak
an infectious disease
results from an invasion of microorganisms
communicable disease
a type of infectious diease that can be transmitted from one person to another person. not all dieseases are comunicable
nonpathogens
do not cause disease and can help maintain body processes
pathogens
capable of causing disease in a humen host. A germ
infectious agent
the pathogen(germ) that causes diseases
reservoir
includes places in the enviroment where the pathogen lives (this includes people animals and insects, medical equiptment, and soil and water).
Portal of exit
is the way the infectious agent leaves the reservoir (through open wounds, aerosols, and splatter of body fluids including coughing, sneezing, and saliva)
Mode of transmission
is the way the infectious agent can be passed on (through direct or indirect contact, ingestion, or inhalation).
