艾滋病出现并成为社会一大问题已有数十年的历史。其间以1983年发现其病原体是人免疫缺陷病毒(HIV)为转折点,人们对艾滋病的发病机制和治疗方法进行了大量、长期的、积极的研究与开发。迄今,我们已能对艾滋病做出如下定义,即它是由HIV感染引起担负免疫作用的细胞死亡、进而发病产生各种并发症、且具有很高死亡率的一种病毒感染疾病。 AIDS has emerged and has become a major social problem for decades. In 1983, the pathogen was found to be human immunodeficiency virus (HIV) as a turning point, people have a lot of long-term, positive research and development on the pathogenesis and treatment of AIDS. To date, we have been able to define AIDS as a viral infection that causes the death of an immunocompetent cell from HIV infection, which in turn leads to complications and has a high mortality rate.
