Chain of Infection (6)
Infectious Agent
Reservoir
Portal of Exit
Mode of Transmission
Portal of Entry
Host
it is the microorganisms that include bacteria, viruses, fungi, and protozoa.
Infectious Agent
they are the permanent residents of the skin and within the body, where they survive and multiple without causing illness
Resident Organisms / Normal Flora
the ability to produce disease

Reservoir
Portal of Exit includes sites such as
blood
skin
mucous membranes

genitourinary (GU) tract
gastrointestinal (GI) Tract
transplacental mother (mother to fetus)

Colon
Staphylococcus aureus major reservoir
