"The chain of infection" refers to a series of events that lead to the spread of infection. This concept is crucial in understanding how infections are transmitted and includes various components such as the infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host. By identifying each link in this chain, healthcare professionals can target interventions that break the chain to prevent the transmission of infections.

Understanding this concept is essential for infection control practices, as it allows caregivers to recognize the pathways through which pathogens spread and implement appropriate measures to prevent outbreaks. This knowledge is foundational in fields such as nursing, where the health and safety of patients rely significantly on controlling and preventing infection.
