Your immune system eventually becomes worn down and exhausted.<\/p>\n<p>When not on ART, your body produces CD4 cells to fight the infection. But HIV uses these cells to make more virus.

When viral load is detectable, your immune system is in overdrive. It is burns up energy and becomes exhausted.<\/p>\n<p>The increased activity is called immune activation or immune inflammation.<\/p>\n<p>It increases the risk of serious illnesses that were not previously linked to HIV.
