How long does the AIDS virus survive? What are the symptoms of patients during the window period

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. The 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 when the immune system is disrupted by HIV, the human body loses the opportunity to replicate immune cells due to low resistance, thereby infecting other diseases and leading to various complex infections and death. The incubation period of AIDS virus in the human body is 12 to 13 years on average. Before becoming AIDS patients, the patients looked normal, and they could live and work without any symptoms 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 the human AIDS virus HIV-1 originated from wild chimpanzees, and the virus may have evolved 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, the United States, 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 young foreigner traveling to China died soon after he became ill and was admitted to Peking Union Medical College Hospital. It was later confirmed that he died of AIDS. This is the first time that AIDS has been found in China.

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 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.
