What is the origin of AIDS? It is better to know these common sense in advance to prevent AIDS

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 initially spread in West Africa, and an African man was infected after having sex with other primates. At that time, the man began to suffer from AIDS after having sex with other primates.

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 the human AIDS virus 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 a hospital in Beijing, 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).

AIDS is a serious threat to human survival, which has attracted the attention of the World Health Organization and governments of all countries. AIDS is spreading faster and faster around the world, posing a serious threat to human health and social development and becoming the fourth killer of human health. Since AIDS was first recognized in June 1981, the United Nations Programme on AIDS announced on May 30, 2006 that there were 65 million people infected with HIV in the world, 2.5 million of whom died. By the end of 2005, 38.6 million people were living with HIV worldwide, 4.1 million people were newly infected with HIV that year, and another 2.8 million people died of AIDS. On July 29, 2008, the United Nations AIDS Programme released the Report on AIDS Prevalence in 208 on Tuesday. The report points out that in 2007, the global AIDS prevention and control efforts made remarkable progress, the AIDS epidemic eased for the first time, the number of AIDS infected people and AIDS infected people increased compared with 2001, and the global AIDS death toll still increased compared with 2001.
