How long can AIDS virus survive? Introduction of knowledge points about AIDS window symptoms

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. 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, 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 without symptoms 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 that human HIV HIV-1 originated from wild chimpanzees through field investigation and genetic analysis, and the virus may have evolved from simian immunodeficiency virus SIV. In fact, the origin of AIDS should be in Africa. In 1959, Congo was still a French colony. A native from the forest was invited to participate in a study related to blood borne diseases. After testing his blood samples, they were refrigerated and dusted down for decades. Surprisingly, decades later, this blood sample has become an important clue to unlock 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).
