A
Antibiotic resistance
B
Mode of transmission
C
Reservoir
D
Susceptible host
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 if it matches one of these components.
Recognize that 'Antibiotic resistance' is a characteristic of some infectious agents but is not itself a necessary component in the chain of infection.
Conclude that 'Antibiotic resistance' is NOT a necessary component in the chain of infection, while 'Mode of transmission,' 'Reservoir,' and 'Susceptible host' are essential parts.
