Viral load refers to the amount of HIV in the blood. An undetectable viral load is when the amount of HIV in the blood is so low that it canât be measured. Antiretroviral therapy (ART) reduces viral load, ideally to an undetectable level, when taken consistently and correctly.
Untreated, HIV reduces the number of CD4 cells (T cells) in the body. This damage to the immune system makes it harder and harder for the body to fight off infections and some other diseases. Opportunistic infections or cancers take advantage of a very weak immune system and signal that the person has AIDS. Learn more about the stages of HIV and how to know whether youâre infected. What Is HIV? HIV stands for human immunodeficiency virus. It is the virus that can lead to acquired immunodeficiency syndrome, or AIDS, if not treated. Unlike some other viruses, the human body canât get rid of HIV completely, even with treatment.
