Transmitting Infection
Indirect contact

Pathogens are passed along on inanimate
objects

Transmitting Infection
Airborne
Pathogens are carried
through the air
 Cling to surroundings
and are spread

Transmitting Infection
Vector-borne

Insects carry pathogen from
host to host
Flea
Mosquito
Tick

Transmitting Infection
 How
you get an infection…
– Causative agent
– Reservoir
– Portal of exit
– Mode of transmission
– Portal of entry
– Susceptible host…breaking the chain!

Causative agent
– pathogen

Chain of Infection

Reservoir
– area where the
pathogen can live


Portal of exit
– way for the pathogen to
escape from the
reservoir

– way to enter new
reservoir
