Summary Introduction
Introduction:
Immune deficiency disease induces the conditions in which the body faces difficulties such as the minor infections. The virus responsible for HIV is a retrovirus that damages the immune system of the body. The human immune virus weakens the immune system which allows many of the pathogens to enter the human body.
