Quizplus · Accepted Answer

The correct sequence for the chain of infection starts with the reservoir of the infectious agent (where the pathogen lives and multiplies), followed by the portal of exit (the path by which the pathogen leaves the reservoir), transmission (how the pathogen is spread to another host), portal of entry (how the pathogen enters a new host), and finally, the susceptible host (an individual who can become ill from the pathogen).
