The causes and origination of HIV/AIDS:

According to history, the HIV-1 virus was believed to be found in chimpanzees of the subspecies Pan troglodytes troglodytes living in the forests of the Central African nations (Gabon, Cameroon, Equatorial Guinea, and the Central African Republic, the Republic of the Congo).

Whereas the HIV-2  virus, less infected confined to West Africa, along with its closest relative, a virus of an old world monkey inhabiting Guinea-Bissau, southern Senegal, Liberia, Guinea, western Ivory Coast & Sierra Leone.

It’s believed by researchers that, the first infection of simian immunodeficiency viruses (SIV) to HIV in humans occurred in 1920 in Kinshasa, the capital and largest city in the D. R. Congo that led to the global pandemic.

The HIV infection continues to spread from some parts of Africa to Haiti in the 1960s & the region of Caribbean during the home return of the Haitian professionals in the colonial D. R. Congo. It then spread in the 1970 to New York City and later in the decade to San Francisco. It is believed and said by scientists that, the AIDS epidemic that emerged in the 1980s was the result of cross-species transmissions of another monkey virus, SIV (simian immunodeficiency viruses). According to research, the chimps’ infected blood got into the wounds or cuts of the hunters. It’s also believed that, African hunters ate the infected chimps which lead to the results the HIV infection. It's as well believed the HIV/AIDS virus spread from chimpanzees and gorillas to humans.

The HIV infection is spread through anal and vaginal sex (unprotected sex), breastfeeding mothers to babies, infected blood transfusions, infected tools (hypodermic needles), and mother to unborn child (during pregnancy).

The infection is also spread through some bodily fluids in the likes of sweat, tears, saliva, etc. The risk of transmitting the virus through oral sex is uncommon.
