9. HIV History
A type of chimpanzee in West Africa is the source of HIV infection in humans. The chimpanzee version of the immunodeficiency virus was transmitted to humans and mutated into HIV when humans hunted these chimpanzees. Over decades, the virus slowly spread across Africa and later into other parts of the world.

10. HIV History
The earliest known case of infection with HIV-1 in a human was detected in a blood sample collected in 1959 from a man in Kinshasa, Democratic Republic of the Congo. (How he became infected is not known.) Genetic analysis of this blood sample suggested that HIV-1 may have stemmed from a single virus in the late 1940s or early 1950s.

 Contact with semen
  Contact with vaginal fluids

17. HIV Non-sexual Transmission
Non-sexual transmission can occur by :
Transfer of blood
From an infected mother to her infant through breast milk

20. AIDS (HIV Infection)
AIDS is a condition in humans in which progressive failure of the immune system allows life-threatening opportunistic infections and cancers to thrive. Without treatment, average survival time after infection with HIV is estimated to be 9 to 11 years, depending on the HIV subtype
