Question

The links in the chain of infection from left to right in this figure (Figure 26.1) are

Choose one:
A. reservoir, transmission, susceptible host, organism.
B. transmission, organism, reservoir, susceptible host.
C. susceptible host, reservoir, transmission, organism.
D. organism, reservoir, transmission, susceptible host.

Answer 1

The correct order of the links in the chain of infection is transmission, organism, reservoir, susceptible host.

Step-by-step explanation:

The correct answer is B. transmission, organism, reservoir, susceptible host. In the chain of infection, the first link is transmission, which refers to how the pathogen is passed from one individual to another. The pathogen then enters the organism or the new host. The reservoir is the source or location where the pathogen normally lives and grows. Finally, the susceptible host is the individual who is at risk of being infected by the pathogen.
