Describe the possible long term effects of HIV on the immune system

Explanation:

HIV attacks a specific type of immune system cell in the body. It's known as the CD4 helper cell or T cell. When HIV destroys this cell, it becomes harder for the body to fight off other infections. When HIV is left untreated, even a minor infection such as a cold can be much more severe.

HIV destroys CD4 cells (also called T cells or helper cells), which are critical to the immune system. CD4 cells are responsible for keeping people healthy and protecting them from common diseases and infections. As HIV gradually weakens the body's natural defenses, signs and symptoms will occur.
