On June 5, 2011 (May 4, 2011 in the lunar calendar), the world's first cured case of AIDS was miraculously reborn. On June 5, 1981, the Centers for Disease Control and Prevention in Atlanta introduced the medical history of five AIDS patients in the Morbidity and Mortality Weekly. This was the first official record of AIDS in the world. As of June 5, 2011, 30 years have passed, more than 25 million people around the world have died of AIDS, and today, there are more than 33 million people living with AIDS. Thirty years after the discovery of HIV, the Associated Press reported on the 3rd that the world's first cured case of AIDS appeared! This case shocked the entire medical community! Timothy Ray Brown is an American leukemia patient who also suffers from AIDS. From the perspective of the medical community, Brown is already about to step into the grave. However, after receiving a bone marrow transplant, Brown was miraculously reborn. This incident shocked the medical community, and doctors saw the miracle of the medical community in him: the end of AIDS. Brown is an American leukemia patient and also suffers from AIDS. In 2007, he came to Berlin and found Dr. Huth from the University of Heidelberg. Huth decided to undergo a bone marrow transplant to treat leukemia first. The result was unexpected. After three years of clinical observation, this transplant also cured Brown's AIDS. It turns out that the match of bone marrow donors is not only very consistent, but also has a mutant gene in the bone marrow that can naturally resist HIV. Previous studies have found that this variant gene exists only in a small number of Nordic people. Most scientists say this method is unlikely to be used for other AIDS patients. Bone marrow transplants are expensive, complex and risky, and require finding people with genes that resist HIV. According to current research, descendants of Nordic people have this characteristic. It is difficult to find accurate bone marrow donors, which only accounts for a small proportion of all donors. Nobel Prize winner Sinossi said: "Although this method is costly and risky, from the perspective of researchers, I have to say that this is an improvement. At least it tells us that AIDS can be cured. It has been 30 years since Brown and his dog were discovered by humans on June 5, 1981, since the HIV virus was discovered. Just as HIV turns 30 years old, the world's medical technology field has sounded the clarion call for elimination and will make every effort to eliminate this terrible virus from the world. The source of this driving force is scientific progress and financial pressure. It is reported that in developing countries around the world alone, the annual cost of AIDS treatment has reached US$1.3 billion.
