HIV is a virus that can attack the human visceral system. It targets the T4 lymphoid tissue, which is the most important part of the human immune system, causing extensive damage to the T lymphoid tissue and resulting in highly fatal internal failure. The virus is permanently infected in the region, disrupting the immune balance and making the human body a carrier of various diseases. When the immune system itself does not cause any diseases, HIV does not cause any diseases. After HIV is destroyed, the human body loses the opportunity to replicate immune cells due to low resistance, thereby infecting other diseases, leading to various complex infections and death. The incubation period of HIV in the human body averages 12 to 13 years. Before becoming a AIDS patient, the patient looked normal and could live and work Asymptomatic for many years.
Scientific research found that AIDS was first spread in West Africa, and it was infected by an African man who had sex with other primates. At that time, the man began to have AIDS after having sex with other primates and then with other homosexuals.
An international research team composed of scientists from the United States, Europe and Cameroon said that they confirmed through field investigation and genetic analysis that human HIV - originated from wild chimpanzees, and the virus probably came from the evolution of simian immunodeficiency virus SIV. In fact, the origin of AIDS should be in Africa. In 1959, Congo remained a legal colony. An indigenous person who came out of the forest was invited to participate in a study related to blood borne diseases. After testing, his blood samples were refrigerated for decades. Surprisingly, decades later, blood samples became an important clue to solve the source of AIDS.
AIDS originated in Africa and then immigrated to the United States. On June 5, 1981, the Centers for Disease Control and Prevention in Atlanta briefly introduced the medical history of five AIDS patients in the incidence rate and Mortality Weekly, which was the first official record of AIDS in the world. In 1982, the disease was named "AIDS". Soon after, AIDS spread rapidly to all continents. In 1985, a foreign youth traveling in China died quickly after checking into Peking Union Medical College Hospital, and was confirmed to have died of AIDS. This is the first time that AIDS has been discovered in China (see Zeng Yi: AIDS epidemic trend, research progress and containment strategies).
