Portal Of Exit Pathway
1. Pathogen. For an infection to occur, a microbe capable of causing disease must be present.
2. Reservoir. Reservoir is a French word that means
“storehouse.” Here, we are using it to mean a place where microbes can grow and multiply. Possible reservoirs for microbes include the bodies of people and animals, bodies of water, and food.
3. Portal of exit. Portal comes from the Latin word for
“gate.” For an infection to occur, the microbe must have a way of leaving the reservoir, or a portal of exit. The portal of exit varies depending on the pathogen and the reservoir.
When the reservoir is a human or animal body, the portal of exit may be the respiratory tract, the digestive tract, the genitourinary tract or breaks in the skin.

Indirect transmission means that pathogens are spread by way of a contaminated surface or object. Usually this situation occurs when an infected person touches something and then someone else touches that same object. For example, if you have a cold and blow your nose into a tissue, and someone else picks up the tissue to throw it away without wearing gloves, that person can get your cold by indirect contact.
The germs will spread from your nose secretions to the tissue to the other person’s hand.
5. Portal of entry. Just as the pathogen must have a way of leaving the reservoir, it must also have a way of gaining entry to a new reservoir. This is called a portal of entry. In the case of person-to-person (or animalto- person) transmission, potential portals of entry include the respiratory tract, the digestive tract, the genitourinary tract, the eye and breaks in the skin.
6. Susceptible host. Finally, the pathogen must enter a susceptible host, or a person who is capable of becoming infected with that particular pathogen.
Some factors increase a person’s susceptibility to infection, including very young or very old age,
