Crawford, Dorothy H.
Summary: "AIDS was first described in 1981 and just under three years later the Human Immunodeficiency Virus (HIV) was discovered. Confirming that HIV causes AIDS--now accepted by virtually all scientists--took rather longer. But where did HIV come from? When did it first infect us? How did it manage to spread so widely?"--Book jacket.
