Since the 1980s, an incurable infectious disease-“Acquired Immune Deficiency Syndrome” (commonly known as AIDS) appeared in the population, causing a considerable degree of panic, and now it has claimed 33 million lives. After 40 years of research, virologists have almost determined that HIV is transmitted from chimpanzees to humans, but the process of transmission is still divergent. Recently, a book published by Canadian epidemiologist Jacques Pepin put forward his hypothesis that it may be the process of killing chimpanzees by Belgian hunters in the 1920s, which caused the origin and infection when they touched blood.
On June 5, 1981, the US Department of Disease Administration issued a notice stating that a “previously unknown disease” was spreading among young gay men in Los Angeles. This was the first official document of “AIDS”. AIDS has become the most frequently discussed and most easily misunderstood disease. And because pathologists didn’t know much about AIDS in the 1980s, major corrections to AIDS occurred almost every ten years. For example, in the early days of research, it was believed that “West African green monkeys” (Chlorocebus sabaeus) were the original carriers of AIDS. However, in recent years, it has been discovered that other primates in Africa have similar HIV carriers, and chimpanzee viruses seem to be closer. Therefore, the current research on HIV is more focused on chimpanzees.
