The '''Human Immunodeficiency Virus''' ('''HIV''') is the presumed cause of the "[[gay plague]]" of the 1980s (see [[AIDS]]). Infection with virus is believed to interfere with human [[immune system]], creating extremely an high risk of contracting several fatal diseases. Doctors say this leads to death in 75% to 90% of cases, even with treatment.

The '''Human Immunodeficiency Virus''' ('''HIV''') is the virus that causes [[AIDS]] (Formerly known as Gay Related Immunodeficiency syndrome or "[[gay plague]]"). The Virus infects and slowly kills human CD4+ helper T-Cells. With Treatment the progression of HIV infection to AIDS is slowed considerably, but may still progress. As T-cell counts fall a number of opportunistic infections can take hold and normally benign organisms can become deadly.

A French team of researchers has been given primary credit for the discovery, although the American scientist [[Gallo]] apparently discovered it independently.
