Answer:
Step-by-step explanation:
Reservoir > Portal of Exit > Mode of Transportation > Portal of Entry > Susceptible Host > Infectious Disease
The reservoir is a place where the germs in question can thrive. This can be a person or an area or even a health care setting. Sometimes the equipment or furniture.
The portal of exit is how the germ escapes from the reservoir into the surrounding area. This can be by touch if we touch a surface that is infected or by other means.
Mode of transportation would be if we touched an infected surface and touched a patient. We have given the germ a mode of transportation, our hand.
Portal of entry can be by a cut or by mouth or other.
Susceptible hosts are always those with weaker immunities.
