Chain of Infection: Pathogenic microbe such as:

• Portal of Exit/Exit Pathway

• Mode of Transmission/ Means of Transmission

Source of the agent of infection or place where the microbe could grow, survive, and multiply, which could be in humans, animals, food, water, soil, or equipment.

• Susceptible Host

• Reservoir

• Portal of Exit/ Exit Pathway

• Mode of Transmission/ Means of Transmission

A way or manner wherein an infectious agent can leave the reservoir host, which could be through secretions and exudates, tissue specimens, blood, feces, or urine.

• Susceptible Host

• Portal of Entry/Entry Pathway

• Portal of Exit/ Exit Pathway

• Mode of Transmission/ Means of Transmission

Airborne, direct (touching or kissing) or indirect contact (contaminated objects), droplets (coughing sneezing), vector (insect, anthropod, or animal), and vehicle (food, water, drugs).

• Susceptible Host

• Portal of Entry/Entry Pathway

• Portal of Exit/ Exit Pathway

• Mode of Transmission/ Means of Transmission

The way an infectious agent enters a host, which includes body orifices, mucous membranes, and breaks in the skin.

• Susceptible Host

• Portal of Entry/Entry Pathway

• Portal of Exit/ Exit Pathway

• Mode of Transmission/ Means of Transmission

Someone who is prone to infection, especially the elderly, newborn babies, patients who are immune-suppressed or unvaccinated, and those suffering from acute or chronic illness.
