HIV stands for Human Immunodeficiency Virus. This is a virus that attacks the immune system and can cause AIDS (Acquired Immune Deficiency Syndrome).  

Over time, and without treatment, HIV gradually weakens the body's immune system leaving it vulnerable to many infections and cancers that do not normally develop.

AIDS is the late stage of an HIV infection. An AIDS diagnosis indicates HIV has weakened the body's immune system. A person living with AIDS is at risk of suffering from life-threatening infections or cancers.

Learn more about acquiring HIV, testing for HIV, and HIV treatment options.
