Verified step by step guidance1
Understand the concept of the 'chain of infection,' which describes the sequence of events that allows an infectious disease to spread from one host to another.
Identify the six classic components of the chain of infection: infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host.
Review each option given in the problem and determine whether it fits into one of these six components.
Recognize that 'Susceptible host,' 'Mode of transmission,' and 'Reservoir' are all standard components of the chain of infection.
Note that 'Antibiotic resistance' is not a component of the chain of infection but rather a characteristic of some infectious agents that affects treatment, so it is the correct exception.
