Susceptible Host: A person at elevated risk for developing an infection when exposed to an infectious agent due to changes in their immune system defenses.For example, individuals exposed to COVID-19 may not develop an active respiratory infection but can spread the virus to other susceptible hosts via sneezing.For example, infants (up to 2 years old) and older adults (aged 65 or older) are at higher risk for developing infections due to underdeveloped or weakened immune systems.Additionally, anyone with chronic medical conditions (such as diabetes) are also at higher risk of developing an infection.

In health care settings, almost every patient is considered a “susceptible host” because of preexisting illnesses, medical treatments, medical devices, or medications that increase their vulnerability to developing an infection when exposed to infectious agents in the health care environment. As caregivers, it is the NA’s responsibility to protect susceptible patients by breaking the chain of infection. 140 | 4.2 Chain of InfectionAfter a susceptible host becomes infected, they become a reservoir that can then transmit the infectious agent to another person. If an individual’s immune system successfully fights off the infectious agent, they may not develop an infection, but instead the person may become an asymptomatic “carrier” who can spread the infectious agent to another susceptible host. For example, individuals exposed to COVID-19 may not develop an active respiratory infection but can spread the virus to other susceptible hosts via sneezing.
