The presence of a pathogen does not mean that an infection will begin. An infection develops in a cyclical process called the chain of infection, which includes six elements: (1) an infectious agent or pathogen, (2) a reservoir or source for pathogen growth, (3) a portal of exit from the re-servoir, (4) a method or mode of transmission, (5) a portal of entrance into the host, and (6) a susceptible host. An infection develops if the chain remains intact.
