As the world is now starting to understand the Ebola virus, scientists think they found where and when the HIV/AIDS virus originated.
The journal Science, it’s believed that the virus emerged around 1920 in the city of Kinshasa, the capital of the Democratic Republic of the Congo.
The study reveals that the HIV virus was already established and spreading in Africa long before the U.S. Centers for Disease Control and Prevention first took note of it. The CDC’s first record of the illness occurred on June 5, 1981, when an unusual type of “pneumonia” was detected in five homosexual men from Los Angeles.
No one then knew that the deadly strain of the virus, which has since killed an estimated 39 million people, had already taken hold in the Congo some 60 years earlier.
The new research was conducted in an effort to understand how another deadly virus, Ebola, reestablished itself in West Africa.
