infection control

Direct contact person to person
indirect contact person to object to person
droplet transmission coughs/sneezes
vehicle route transmission via food, water, blood or body fluids
airborne transmission dust, evaporated droplets in air, airborne particles, hair/ skin; ventilaton system
vector transmission bird/animal/insect
normal flora microorganisms normally present in the human body that dont cause disease
bacteria single cell organisms that multiply most are non pathogenic; some cause disease
viruses very small organisms; cant live on their own; need host to multiply
fungi grow mainly single cell organisms that uses spores to reproduce
protozoa single cell organisms, found mostly in contaminated food, water of sewage
auto clave device using strem for sterilization
antigen pathogen or any other substance that induces an antibody response
antibody protein specific to a certain antigen that weakens or destroys pathogens
nosocomial hospital related infection; one that is not present or incubating when a patient is admitted to a hospital or healthcare facility
systemic infection infection that has spread to more than one region of the body
sharp instrument with a sharp edge or point, such as a scalpel, scissors or a needle
topical applied to the skin or affected area
anaerobic bacteria bacteria that do not require oxygen to grow
aerobic bacteria bacteria that require oxygen to grow
teratogenic causing abnormalities int the fetus
antiseptic cleansing agent applied to living tissue to destroy pathogens
latent infection one in which the symptoms disappear and recu, while the disease causing agents remains in the body
sterile completely free of pathogens
sterilant substance that destroys or eliminates all forms of microbial life in an inanimate environment
disinfectant chemicl substance that destroys or eliminates specific species of infectious micro organisms. It is not usually efective against bacterial spores.
infection disease process that results fromthe entry and spread of a microrganism
contagious disease disease that is soread from person to person
immunity individual's ability ti fight off disease
active infection infection in which signs and symptoms are present
otitis media onfection of the middle ear
acute infection infection that is time limited
quarantine isolating or separating a client, client-care unit or facility
bactericidal killing microorganisms
local infection infection that is confined to a specific region of the body
sanitization removal of gross contaminants and some microorganisms from instruments, skin and so on; the lowest level of medical hygiene
sterile technique methods to avoid contamination of sterile materials
pathogen microorganism that causes disease
disinfection a more thorough removal disinof contaminants more thorough removal of contaminants than santitization but less through than sterilization
non pathogenic not causing disease
opportunistic infection an infection that doesnt ordinarily cause disease but does so under certain circumstances ie in compromised immune systems; so called because it takes advantage of an "opportunity"
microorganism organism so small that it can only be seen under a microscope
remission period in which a chronic infection shows no symptoms
exacerbation period in which a chronic infection shows symptoms
chronic infection one that is persistent over a long period of time, perhaps life
sanitizer substance that sinificantly reduces the vacterial population in an inanimate environment but does not destroy all bacteria or other microorganisms
bacteriostatic reducing or inhibiting the number of microorganisma
relapse re-emergence of an intial infectin after it appears to have subsided but has not been cured
recurrent infection distinct episode of an infection after recovery fromthe initial infection; may involve the same pathogens or different ones
immunogobulin serum that contains antibodies that can help protect an exposed person from contracting the disease
asepsis state in which pathogens are absent or reduced. There are two principal types of asepsis: medical or surgical
sterilization process of destroying all microorganisms, including bacterial endospores and viruses. This is the highest level of cleanliness
virulence power of a microbe to produce a disease in a particular host
contamination presence of pathogens on an object
PEP treatment after exposure to a pathogen
asymptomatic without clincal signs or symptoms
