Before hiv became well known and widely spread in the 1980s, the earliest case of the virus in the united states was confirmed in 1968 in a young man who never received a blood transfusion or traveled outside of the united states, which led researchers to believe that this virus was present long before the 1960s.

- This information can be used to study the history of transmission events, and also as evidence for the origins of the different viral strains there are two characterized strains of human aids viruses: type 1 (hiv-1) and type 2 (hiv-2.
- The virus was called human immunodeficiency virus (hiv) 1986 also saw the development of first anti-hiv drugs called azidothymidine (azt) or zidovudine the drug was approved in 1987.

In virus hunt, renowned virologist dorothy h crawford takes us inside one of the great research quests of our time--the search for the origin of aids from hospital intensive care wards to research laboratories to the african rain forests, crawford follows the trail of the virus back to its roots deep in africa.
