The human immunodeficiency viruses (HIV) are two species of Lentivirus (a subgroup of retrovirus) that infect humans.Over time, they cause acquired immunodeficiency syndrome (AIDS), [1] [2] a condition in which progressive failure of the immune system allows life-threatening opportunistic infections and cancers to thrive.

Human immunodeficiency virus (HIV) affects a person’s immune system. People with HIV can take medication to prevent it from progressing to acquired immunodeficiency syndrome (AIDS).
AIDS is caused by a human immunodeficiency virus (HIV), which originated in non-human primates in Central and West Africa.
