What is HIV?
In 1985, scientists discovered the human immunodeficiency virus (HIV). HIV is a virus that is transmitted from person to person through the exchange of body fluids such as blood, semen, breast milk and vaginal secretions. Sexual contact is the most common way to spread HIV, but it can also be transmitted by sharing needles when injecting drugs, or during childbirth and breastfeeding. As HIV reproduces, it damages the body's immune system and the body becomes susceptible to illness and infection. There is no known cure for HIV infection.
What is AIDS?
Acquired immune deficiency syndrome, or AIDS, is a condition that describes an advanced state of HIV infection. With AIDS, the virus has progressed, causing significant loss of white blood cells (CD4 cells) or any of the cancers or infections that result from immune system damage. Those illnesses and infections are said to be "AIDS-defining" because they mark the onset of AIDS. Like HIV, there is no known cure for AIDS.

HIV/AIDS - More Than Just a Disease
Soon after the emergence of the AIDS epidemic, it became evident that HIV was much more than just a disease. Unlike any other disease, HIV not only touches the lives of those infected, but it also impacts the lives of virtually everyone on earth. One would be hardpressed to find any group not affected by the HIV epidemic in some way. Simply put, it is probably the single most important public health issue of our time.
