Reservoir or Source
Portal of exit
Mode of Transmission
Portal of entry
Susceptible host
Community Based Nursing - Levels of prevention?: Primary prevention (immunizations)
Secondary prevention (acute illness)
Tertialry prevention (chronic illness)
Humoral Immunity: B cells bind with antigen which synthesizes immunoglobulins (antibodies)

esp w/ bacteria & viruses

medical asepsis: clean technique
Modes of transmission: Contact - direct & indirect
Droplet - w/in 3' (flu)

Vehicles - water, food, blood (norovirus)
Vector - mosquitos
nosociomial: infections from hospital
pathogenic, pathogenicity: productive of disease, being able to produce disease
portals of entry?: same as exit with an emphasis on broken skin
Stages in natural history of disease? & corresponding stages of illness?: Pre-exposure stage
Pre-clinical stage (incubation stage of illness)
Clinical stage (Prodrome & illness stage of illness)
Resolution stage (Convalescence stage of illness)
Tier 1 - Standard Precautions: concerned with blood and body fluids, non-intact skin, mucous membranes, contaminated items.
Tier 2 - Transmission Based Precautions: Contact
Droplet
Airborne
virulence: degree of pathogenicity possessed by organisms
What are some portals of exit?: skin (hands)
mucous membranes
respiratory track
GI track
urinary track
reproductive system
blood
purulent drainage (pus)
What's special about IgM?: When abundant it's a good signifier that the person just contracted the disease (it's 'baby' immunoglobulin)
