This article will cover the primary topics in the history of HIV, from its beginnings to the latest research today.

Scientists are not exactly sure when HIV originated, but they believe it developed from a type of chimpanzee virus in West Africa called the simian immunodeficiency virus.

People who hunted chimpanzees for meat came in contact with the blood containing the virus and contracted HIV. Researchers believe the virus mutated at some point into the human form of HIV.

Researchers collected the earliest detected HIV in 1959 from a man in the Democratic Republic of the Congo. Later, genetic analysis determined the virus might have developed between 19101930.

THE DISCOVERY

There are an estimated 23 millionpeople living with HIV and AIDS worldwide.
