Acquired Immunodeficiency Syndrome, or AIDS. It impairs the immune system to fight infections. AIDS is the final stage of an HIV infection. The time between infection with HIV and the development of an AIDS- defining condition is about ten years. As HIV reproduces, it destroys the body's ability to defend itself by taking over the immune cells. This leaves the body defenseless against possible illnesses. Like all Viruses, HIV is a tiny and simple organism that is energized when it comes in contact with a living cell. When a HIV virus gets energized it can reproduce up to one billion copies of the virus in a single day!

Immediately after infection with HIV, a
