i have to write notes on aids
The first cases of Acquired Immune Deficiency Syndrome (AIDS) were described in 1981 by Michael Gottlied on homosexual men living in Los Angeles, USA. By the end of 1981 epidemiological data indicated that AIDS was an infectious disease transmitted through sexual relations and blood contact. In May 1983, first description of the AIDS infectious agent, the virus LAV (Lymphadenopathic Associated Virus) was given on the basis of the work done by Prof. Montagnier and his team at the Pasteur Institute (Paris). In May 1984, Prof. Robert Gallo (USA) and his team isolated the HTLV III (Human T cell leukemia virus type 3) as infectious agent of AIDS.
