Susceptible host refers to a person who is at increased risk of infection because their defenses are lowered or barriers are compromised. This includes being older or younger, having a weakened immune system, having chronic diseases, or having breaks in skin or mucous membranes that pathogens can enter. Vaccination lowers risk but does not define susceptibility—the immune protection it provides can vary, and even vaccinated people can become infected in some situations. An asymptomatic carrier is someone who harbors and can spread a pathogen without symptoms, not someone defined by their own level of susceptibility. A person with a strong immune system is less likely to be susceptible, not more.
