MODE OF TRANSMISSION
PORTAL OF ENTRY
SUSCEPTIBLE HOST
is something that infiltrates another living thing, like you.
INFECTIOUS AGENT
The invasion and multiplication of microorganisms not normally present in the body
INFECTION
4 examples of infection:
•Bacteria
• Viruses

is any inanimate object that, when contaminated with or exposed to infectious agents, can transfer disease to a new host.
FOMITES
The way out
PORTAL OF EXIT
E.G
NOSE
BLOOD
SKIN
URINE/FECES
PORTAL OF EXIT
Getting around
MODE OF TRANSMISSION

4 Mode of Transmission
