Forty-four years ago today, on June 13, 1981 (May 12, 1981 lunar calendar), the world announced the first case of AIDS. AIDS patients In June 1981, the US Centers for Disease Control first reported to the world five very rare and life-threatening cases, and named the disease "Acquired Immune Deficiency Syndrome", which is now known as AIDS. In recent years, just as people were terrified by the terrible cancer, there has been another plague god - AIDS, which is more terrifying than cancer. First of all, AIDS spreads rapidly, and cancer is not an infectious disease. Secondly, the mortality rate of AIDS is very high, the mortality rate is almost 100%, and there is no report of a complete cure; and although the mortality rate of cancer is also very high, with the development of medicine, if it can be detected early, the cure rate is also increasing. In addition, from the perspective of treatment methods, AIDS currently has basically no effective treatment methods, nor can it be surgically removed; while cancer currently has more treatment and control methods, such as radiation therapy, chemotherapy, and surgical resection. Finally, from the perspective of the impact on the next generation, HIV can be transmitted from mother to baby through the placenta or childbirth process, and even infected mothers may be infected with HIV when breastfeeding; and cancer, although currently believed to be related to genetic factors, is at most statistically significant, not an inevitable link. From this, it can be seen that there is a certain reason why people are more afraid of AIDS than cancer syndrome. In a sense, AIDS is the most serious challenge to human health in the 20th century. There is an old Chinese saying that "when it comes, it will be safe". After all, human beings are the most rational animals. It is a proud character of human beings to be prepared for danger in times of peace and yet not afraid of danger. The emergence of AIDS is a challenge to mankind and a mobilization for mankind. The World Health Organization established the Global AIDS Prevention Programme (GPA) on February 1, 1988 to guide and coordinate the global fight against AIDS. In addition, the World Health Organization has formed an alliance with the United Nations Development Programme (UNDP) to jointly launch a war against AIDS. The great trend of human beings to fight back against AIDS has taken shape. AIDS, as one of the serious diseases that endanger human life, has attracted great attention from medical scientists and biologists around the world. At present, AIDS research has made great progress. The epidemiological characteristics of AIDS have been clarified, and the HIV virus has been successfully isolated and named "Human Immunodeficiency Virus (HIV) "; in short, human beings are not helpless in the face of AIDS. Because of the ferocity and harm of AIDS, it has become one of the hot topics of this century that have attracted worldwide attention. In 1996, tens of thousands of people gathered in Washington to mourn the AIDS victims
