The four occurrences of events that provide the chain of infection are exposure, adhesion, invasion, and infection.

The four occurrences of events that provide the chain of infection are:

Exposure: This is when a person comes into contact with a potential pathogen. It could be through touching contaminated objects or being in close proximity to an infected person.
Adhesion: In this stage, the pathogen attaches itself to a surface, such as the skin or mucous membranes, in order to establish colonization.
Invasion: Once the pathogen has adhered to a surface, it enters the body and starts multiplying.
Infection: This is when the pathogen causes damage to the host and produces noticeable signs and symptoms of disease.
