Human Immunodeficiency Viruses - Cuntorio

In 1981, the first cases of a new disease now called acquired immune deficiency syndrome (AIDS) were recognized. The victims died of rare infections because their immune systems were crippled. The cause was identified two years later by Luc Montagnier and coworkers. AIDS is produced by human immunodeficiency virus (HIV), of which two major classes are known: HIV-1 and the much less common HIV-2.
