Questions about AIDS
What is AIDS?
The word AIDS means "Acquired Immune Deficiency Syndrome". It is an infectious disease due to a virus. (To be more precise. it is due to a retrovirus: "retro" describes more particular biological characteristics of the virus). The disease first appeared in Africa. The virus grows in lymphocytes, which are one group of the white blood cell that defend your body against infections. Once the lymphocytes have been attacked by the virus, the body is open to some infections that would normally have been fought off by its defences. That is why it is called the "immune deficiency syndrome". The word "acquired" is used to distinguish it from some inherited forms of immune deficiency that are present from birth.

Filtering the blood reduces the risk of infection even further, because the virus lives only in the white cells, and filtering removes them.
