Introduction to AIDS:
AIDS is a very harmful infectious disease, which is caused by HIV infection. HIV is a virus that can attack the human immune system. It takes CD4T lymphocytes, the most important cells in human immune system, as its main target, and destroys them in large quantities, making human body lose its immune function.
Therefore, the human body is prone to various diseases and malignant tumors, and the mortality rate is high. The average incubation period of HIV in human body is 8 ~ 9 years. During the incubation period of HIV, you can live and work for many years without any symptoms.
Studies show that AIDS originated in Africa and was brought to the United States by immigrants. On June 5th, 198 1, the US Centers for Disease Control and Prevention published a case report of 5 AIDS patients in Morbidity and Mortality Weekly, which is the first official record of AIDS in the world.
In 1982, this disease is named "AIDS". Soon after, AIDS quickly spread to all continents. 1985, a foreigner who traveled to China fell ill and died soon after being admitted to Peking Union Medical College Hospital, and was later confirmed to have died of AIDS. This is the first case of AIDS in China.
