Role of a nurse in infection control In order for infection and disease to occur in an individual‚ a process involving 6 related components must occur. This process has been referred to as the chain of infection. The six steps or links in the chain are etiologic agent‚ reservoir‚ portal of exit‚ mode of transmission‚ portal of entry and susceptible host. To stop the spread of disease‚ one or more of these links must be broken. 1. Etiologic agent a. Metazoan – multicellular animals many
