infection control Flashcards
1
Q
what is the infection cycle
A
- infectious agent (bacteria, fungus, virus)
- reservoir of pathogen growth
- portal of exit from reservoir
- mode of transmission
- portal of entry to host
- susceptible host
2
Q
what is virulence
A
ability to cause disease
3
Q
what is normal flora
A
microorganisms that inhibit various body sites and part of bodys natural defence
4
Q
what is an opportunist
A
bacteria = normally no problem but potentially harmful
5
Q
reservoir
A
natural habitat of organism that allows growth and multiplication. e.g human, food, soil, water, animals
6

stages of infection
A
- incubation period (invasion and appearance of symptoms)
- prodromal stage- most infectious
- full stage of illness
- convalescent stage

A
- skin and membrane state
- pH levels and GI and GU

8
Q
what is a nosocomial infection
A
acquired via the hospital
9
Q
asepsis
A
the absence of pathogenic micros
10
Q
how to control/eliminate infectious agents
A
- cleansing
- disinfecting
- sterilisation
11
Q
how to control reservoirs
A
- eliminating body fluids
- discarding infectious material
