An Infection That Occurs When the Body's Defences are Weakened

Question

An infection that occurs when the body's defences are weakened is called
A)contagious.
B)selective.
C)opportunistic.
D)symbiotic.
E)chronic.

Accepted Answer

An opportunistic infection is one that takes advantage of a weakened immune system, such as in individuals with HIV/AIDS or undergoing chemotherapy. Contagious refers to a disease that can be easily transmitted from person to person. Selective and symbiotic do not relate to infections specifically. Chronic refers to a long-term condition rather than an infection that occurs due to weakened defences.
