HIV infection in humans came from a type of chimpanzee in Central Africa. The chimpanzee version of the virus (called simian immunodeficiency virus, or SIV) was probably passed to humans when humans hunted these chimpanzees for meat and came in contact with their infected blood.
How easy is it to get AIDS?

Can u get AIDS from kissing?
Deep, Open-Mouth Kissing Although very rare, transmission can occur if both partners have sores or bleeding gums and blood from the partner with HIV gets into the bloodstream of the HIV-negative partner. HIV is not transmitted through closed-mouth or “social” kissing with someone who has HIV.
Can humans breed with any other animals?
