HIV is a virus that can attack the human visceral system. It targets the most important T4 lymphoid tissue in the human immune system, extensively damaging T4 lymphoid tissue and causing highly fatal internal failure. This virus spreads throughout the region for life, disrupting the immune balance and making the human body a carrier of various diseases. HIV itself does not cause any diseases, but rather, after the immune system is disrupted by HIV, the human body loses the opportunity to replicate immune cells due to low resistance, thus infecting other diseases and dying from co infection. The incubation period of AIDS virus in the human body is 12-13 years on average. Before becoming a AIDS patient, the patient's appearance looks normal and can live and work for many years without symptoms.
Scientific research shows that AIDS first spread in West Africa. African men became infected after having sex with other primates. At that time, men began to become infected with AIDS after having sex with other primates and with other men of the same sex.
The international research team composed of scientists from the United States, Europe and Cameroon said that they proved that human HIV HIV-1 originated from wild chimpanzees through outdoor investigation and genetic analysis, and the virus is likely to evolve from simian immunodeficiency virus SIV. In fact, the origin of AIDS should be in Africa. Congo was a colony in 1959. The natives who came out of the forest were invited to participate in the study of blood borne diseases. After his blood sample test, he was refrigerated for decades. Surprisingly, decades later, this blood sample became an important clue to solve the source of AIDS.
AIDS originated in Africa and was brought to the United States by immigrants. On June 5, 1981, the Centers for Disease Control and Prevention in Atlanta, USA, briefly introduced the medical history of five AIDS patients in incidence rate and Mortality Weekly, which was the first official record of AIDS in the world. In 1982, the disease was named "AIDS". Before long, AIDS spread rapidly to all continents. In 1985, a foreign youth traveling in China died immediately after being admitted to Peking Union Medical College Hospital due to illness, which was confirmed as AIDS. This is the first time that AIDS has been found in China.
AIDS is a serious threat to human survival and has been highly valued by the World Health Organization and governments of all countries. AIDS is spreading more and more rapidly around the world, which seriously threatens human health and social development and becomes the fourth killer threatening people's health. The United Nations Programme on AIDS announced on May 30, 2006 that since AIDS was first recognized in June 1981, there have been 65 million people infected with AIDS in the world in 25 years, including 2.5 million deaths. By the end of 2005, 38.6 million people in the world were infected with AIDS, 4.1 million people were infected with AIDS at that time, and 2.8 million people died of AIDS. On July 29, 2008, the United Nations AIDS Programme released the Report on AIDS Epidemic Situation in 2008 on Tuesday. The report shows that in 2007, the global efforts to fight AIDS have made remarkable progress. The AIDS epidemic eased for the first time, and the number of new AIDS infected people and the number of deaths due to AIDS declined. However, the situation in various countries is uneven, and the total number of AIDS patients in the world is still high. In 2007, 2.7 million people were newly infected with AIDS in the world, 300000 fewer than in 2001, and 2 million people died of AIDS, 200000 fewer than in 2001.
