Features: Experts from the Harvard University School of Public Health successfully detected 70 out of 200 African green monkeys' peripheral blood samples containing a virus highly similar to human HIV, fully proving the aforementioned hypothesis of zoonotic transmission from monkeys. This epidemic spread caused by these green monkeys living in Central and East Africa is not limited to local residents, as they often inhabit areas near human settlements or gather in national tourist resorts and parks. Occasionally, they bite tourists, thereby transmitting monkey AIDS virus to humans (most commonly observed among Haitians living in the region of the Democratic Republic of the Congo), who then carried the virus to the United States. Subsequently, through the United States, a country with the highest population mobility in the world, the virus spread globally. Experts believe that after the monkey AIDS virus enters the human body, it can mutate and evolve into human HIV.
Second, chimpanzees living in Africa are the source of the HIV virus. Researchers at the University of Alabama at Birmingham announced that they have convincing evidence that HIV originated from gorillas in West Africa. Using molecular analysis techniques, they studied four isolated virus samples and found that three of them share genetic characteristics extremely similar to human HIV. These three viruses were collected from one of the four branches of African chimpanzees, which live in Cameroon, Equatorial Guinea, the Congo, and the Central African Republic. Long-term observations have shown that human AIDS first emerged in this region. Moreover, the Ebola River, which has repeatedly caused panic with its virus "creations," flows silently here day and night. Research findings indicate that the Ebola virus, which has repeatedly challenged humans, is also a "creation" of monkeys and apes at play. In fact, scientists have long suspected that chimpanzees are the "culprits" behind the spread of AIDS, but hypotheses require scientific validation.
Bette Nesheim, an AIDS expert at the U.S. Centers for Disease Control and Prevention, also concluded based on their research findings that the transmission of HIV from chimpanzees to humans can be definitively traced to West Africa. She stated that local indigenous people may have hunted chimpanzees and other animals for food, becoming accidentally infected during the process and subsequently spreading the virus. P4
