Meaning of AIDS

The word AIDS stands for Acquired Immuno Deficiency Syndrome. This means a deficiency of the immune system, acquired during the lifetime of an individual indicating that it is not a congenital disease [disease or abnormality present from birth]. ‘Syndrome’ means a group of symptoms.


AIDS was first reported in 1981 and in the last twenty-five years or so, it has spread all over the world.

Luc Montagnier, Françoise Barré-Sinoussi, and their colleagues at the Pasteur Institute in Paris were the first to report the discovery of the virus now called the human immunodeficiency virus (HIV) associated with AIDS.
