Infection - Pathophysiology

Pathophysiology

There is a general chain of events that applies to infections. For infections to occur a given chain of events must occur. The chain of events involves several steps—which include the infectious agent, reservoir, entering a susceptible host, exit and transmission to new hosts. Each of the links must be present in a chronological order for an infection to develop. Understanding these steps helps health care workers target the infection and prevent it from occurring in the first place.
