In brief: Antigenicity
Hiv-1 is the major cause of aids in the usa.
It differs from hiv-2 by its molecular structure. Hiv-2 has predominantly been seen in africa and appears less pathogenic than hiv-1, although the differences ultimately have little weight on outcome. An antigen is the chemical structure which stimulates the formation of antibodies, and the difference is a serological one.
