How is the virus HIV formed?
Answers
Transmission from non-humans to humans. The majority of HIV researchers agree that HIV evolved at some point from the closely related simian immunodeficiency virus (SIV), and that SIV or HIV (post mutation) was transferred from non-human primates to humans in the recent past (as a type of zoonosis).

Explanation:
(1)Transmission from non-humans to humans. The majority of HIV researchers agree that HIV evolved at some point from the closely related simian immunodeficiency virus (SIV), and that SIV or HIV (post mutation) was transferred from non-human primates to humans in the recent past (as a type of zoonosisThere are two types of HIV: HIV-1 and HIV-2. HIV-1 is more virulent, easily transmitted and is the cause of the vast majority of HIV infections globally.(2)The pandemic strain of HIV-1 is closely related to a virus found in chimpanzees of the subspecies Pan troglodytes troglodytes, which live in the forests of the Central African nations of Cameroon, Equatorial Guinea, Gabon, the Republic of the Congo (or Congo-Brazzaville), and the Central African Republic. HIV-2 is less transmittable and is largely confined to West Africa, along with its closest relative, a virus of the sooty mangabey (Cercocebus atys atys), an Old World monkey inhabiting southern Senegal, Guinea-Bissau, Guinea, Sierra Leone, Liberia, and western Ivory Coast.
