Secondary Immune Deficiency Disease Defined

A secondary immune deficiency disease occurs when the immune system is compromised due to an environmental factor. Examples of these outside forces include HIV, chemotherapy, severe burns or malnutrition.

In contrast, primary immunodeficiency diseases (PIDD) are a group of disorders caused by inherited or genetic defects in the cells and tissues of the immune system.
