Various fringe<unk>  have arisen to speculate about purported alternative<unk>  for the human immunodeficiency virus (HIV) and the acquired immunodeficiency syndrome <unk> , with claims ranging from it being due to accidental exposure to supposedly purposeful acts. Several inquiries and investigations have been carried out as a result, and each of these<unk>  has consequently been determined to be based on unfounded and/or false information. HIV has been shown to have evolved from or be closely related to the simian immunodeficiency virus (SIV) in West Central Africa sometime in the early 20th century. HIV was discovered in the 1980s by the French scientist Luc Montagnier. Before the 1980s, HIV was an unknown deadly disease.
