Definition for Immunocompromised
From Biology Forums Dictionary
A person who has an immunodeficiency of any kind is said to be immunocompromised. Immunodeficiency (or immune deficiency) is a state in which the immune system's ability to fight infectious disease is compromised or entirely absent. Most cases of immunodeficiency are acquired (secondary), but some people are born with defects in their immune system, or primary immunodeficiency. Transplant patients take medications to suppress their immune system as an anti-rejection measure, as do some patients suffering from an over-active immune system.
