Origin and activities of human lentivirus particles

It is proposed that human immunodeficiency lentivirus particles (HIV) are of ancient origin and have existed at a low level for centuries. The recent increase in the extent and effects of this lentivirus have occurred principally from change in the saccharide component of the human diet. This increased greatly the supply of oxalic acid required to produce the uracil component of lentivirus RN.
