How did a chimpanzee in Africa spread AIDS to the local population, and then from there to the rest of the world?

In 1981, the world’s first case of AIDS was found in Kinshasa, the capital of Zaire.


But it is virtually certain that long before the first cases of AIDS were first documented and named. The world already has 100,000 to 300,000 people infected with HIV. Sure enough, in 1989, scientists found a blood sample in Kinshasa that had tested HIV-1 positive in 1959, the earliest definitive trace of AIDS.


In other words, BY 2021, AIDS will be at least 60 years old. With the progress of modern medicine, many “incurable diseases” have already become “minor diseases” that can be injected. Only AIDS remains firmly in the “note of Death”.


From the moment the VIRUS was discovered, researchers began to trace its origins. And surprisingly, the origin of the virus is actually in southern Cameroon in Africa. In the 1920s, scientists in Cameroon discovered a virus that closely resembles HIV, SIV, or simian immunodeficiency virus, in primates (chimpanzees).


And the ancestor of HIV is the simian immunodeficiency virus. SIVcpz in chimpanzees and HIVgor in gorillas originated in Cameroon. So the question is, how did this chimpanzee virus get to humans, and how did it get to the world?


Some people spread the folk, this is because of the Local People in Africa and orangutans have carried out reproductive behavior. But in fact, in any study, the results had nothing to do with reproductive behavior. The most widely accepted theory in the scientific community is the “wounded hunter” theory.


African hunters, some remote places still have the habit of hunting wild jungle animals. Bushmeat is also an important source of nutrition for local tribes. Chimpanzees and other primates, like humans, have a predator-prey relationship with humans. How does HIV come about? It is possible that some of the chimps infected with SIVcpz were killed and the hunters were injured. In this way, the chimpanzee’s SIVcpz virus entered the human body through the hunter’s wound, and the hunter became infected with the SIVcpz virus.


So when the body’s immune system senses the invasion of SIVcpz, it starts attacking it. Most SIVcpz is destroyed by the body’s immune system, while the lucky few that are not survive and mutate. Eventually it became HIV-1, and that’s how HIV spread from person to person.




So the next question is, how did the virus spread from Africa to the rest of the world? First, we set our sights on Kinshasa, the most prosperous city in Africa in the late 19th and early 20th centuries. The prosperity of the area attracted countless migrant workers, and the popularity and money of the area attracted many prostitutes.


The young negroes were full of energy, and the arrival of prostitutes was a perfect outlet. They’re trying to get money out of young people’s pockets, but with money is basically HIV. Moreover, kinshasa had little idea of public health.


In the region, unsanitary treatment practices, such as the sharing of a single needle by hundreds of people, are also a hotbed of AIDS. What’s more, almost all popular places in Africa at that time were basically colonized by western countries.


The colonists exploited the cheap resources, used the cheap labor, and then brought it back to their home countries and turned it into money. Then, of course, they brought back not only money from the land, but ALSO AIDS.


So far, the former colonial power, now the superpower, the United States. This super-international country, which has grown its population by absorbing immigrants, has become the birthplace of the global AIDS pandemic.
