What is the chain of infection?
- The process by which an organism spreads from one carrier to another, either by direct transmission (infectious host to vulnerable host) is known as the chain of infection.
- Or, indirect transmission (infected host to susceptible host) (which involves an intermediate carrier like an environmental surface or piece of medical equipment).
- The chain can be broken at six locations, and a germ can be prevented from infecting another individual.
- The six linkages of an infectious chain are:
- infectious agent
- reservoir
- portal of exit
- route of transmission
- portal of entry
- susceptible host
