Chain of infection - ANSWER✔✔-infectious agent
reservoir
portal of exit
transmission
portal of entry
susceptible host
Infectious agent - ANSWER✔✔-pathogens- capable of causing disease
Reservoir - ANSWER✔✔-a place where pathogens survive and multiply
human body is the most common
portal of exit - ANSWER✔✔-for infection to spread, a pathogen must exit the reservoir.
most frequent is through body fluids
trasmission: direct & indirect contract - ANSWER✔✔-direct- involves touching, kissing

private room
negative airflow pressure
door closed except entering/exiting

Vector - ANSWER✔✔-organism that carries a pathogen to a susceptible host by biting or stinging,

Portal of entry - ANSWER✔✔-normal body openings such as the eye, nostrils, mouth, urethra, vagina
and anus
abnormal openings such as cuts, scrapes, and surgical incisions
Susceptible host - ANSWER✔✔-a person who is at risk for infection bc of inadequate defenses against
the invading pathogen
Primary defense mechanisms - ANSWER✔✔-skin-tough & resilient, prevents entry of pathogens
respiratory tract- mucous membranes that trap pathogens; cilia; cough & sneezing expel organisms
eye- tears wash infective organisms from eyes
