HIV
HIV (human immunodeficiency virus) is the virus that causes acquired immune deficiency syndrome, or AIDS. People infected with HIV, usually spread through bodily fluids from unprotected sex or shared needles for drug use, don't always have AIDS. HIV symptoms can be dormant (non-active) for years, though many experience flu-like symptoms shortly after becoming infected. There is no cure for HIV, which is diagnosed with a blood test.
