How many links are there in the Chain of Infection?

The Chain of Infection consists of six links that describe the process through which an infection is transmitted. These links include the pathogen, the reservoir of the pathogen, the portal of exit from the reservoir, the mode of transmission, the portal of entry to a susceptible host, and the susceptible host itself.

Understanding these six components is critical in infection control practices, especially in healthcare settings. By identifying and breaking any one of these links, the transmission of infections can be effectively prevented.

Having a clear grasp of the Chain of Infection is essential for healthcare professionals, as it enables them to implement strategic measures to reduce the spread of infections among patients and within the community.
