Infection Flashcards
direct contact
person-to-person
indirect contact
object in between
droplet
spread via delivery or respiratory secretions
aerosol
suspended in air
vector borne
spread via insects or animals
nosocomial infections
spread in health care facility
pathogenicity
capacity of microbes to cause disease
virulence
degree of pathogenicity of a specific microbe
how invasive is it
how toxic
ability to adhere to cells/tissues
ability to avoid host defenses/mutate
super infections/superbugs
multidrug resistant forms of existing diseases
stages of infection
incubation
prodromal
acute
convalescent
resolution
incubation
time between entry of organism and signs of infection
microbe begins to colonize and reproduce
prodromal
S&S appear, usually vague
acute
full development of infection, clinical manifestations peak
convalescent
end of acute phase, signs subside and body begins to return to normal state
resolution
back to normal state
local
confined to specific area
focal
spreads from local to many sites and other tissues
systemic
spreads to many sites and tissues
mixed
several pathogens establishing at same site
acute (pattern of infection)
rapid appearance, severe s&s, short course
chronic
low grade s&s, persist longer
primary
initial infection caused by initial pathogen
secondary
follows primary, caused by microbe other than primary
subclinical/subacute
no s&s but persists for long periods of time
