Acquired Immune Deficiency Syndrome
A serious (often fatal) disease of the immune system transmitted through blood products especially by sexual contact or contaminated needles. Caused by the human Immuno-Deficiency virus which attacks the central nervous system. The virus causes the amount of T Cells that are used to fight infection to drop to dangerously low levels. In someone who has acquired aids, it is not the disease that actually kills them, it is the fact that their immune system is degenerated by the virus leaving them prey to opportunistic infections like influenza.
