An individual with little resistance to infections is referred to as susceptible. This term indicates that the person's immune system is not adequately equipped to fend off pathogens, making them more likely to contract illnesses.

Immunocompetent describes someone whose immune system is functioning properly and is capable of responding to infections effectively. Infected refers to the condition of having an infectious agent within the body, while contagious describes someone who is capable of spreading an infection to others. Therefore, susceptibility focuses specifically on the vulnerability to infections due to inadequate immune defenses.
