Quizplus · Accepted Answer

All four factors listed (pathogen, reservoir, portals of exit and entry, mode of transmission, and susceptible host) must be present for an infection to take place. The pathogen must be present in a reservoir (such as a human body, animal, or environmental object) and must have a way to enter and exit that reservoir (through portals of entry and exit). The pathogen must also have a way to be transmitted from one host to another (mode of transmission). Finally, there must be a susceptible host who is not immune to the pathogen and can become infected.
