获得性免疫缺陷综合症(Acqired I-mmunodeficiency syndrome,简称AIDS)或称“爱滋病”,是近年新发现的一种疾病,其特征为细胞免疫缺陷,致使患者发生条件性感染和恶性肿瘤。死亡率很高。成人和儿童均可为患,同性恋者和注射用药者为多见。有传染性,但病原尚未完全肯定。该病于70年代末在海地首次出现。1979年在美国纽约和加里福尼亚已有病例报告,1981年美国疾病控制中心(CDC)正式将该病定名为AIDS,并提出诊断该病的两条标准:(1)至少有中度以上的细胞免疫缺陷指征[60岁以下的人有条件性感染或卡波济氏肉瘤(Raposi’s sarcoma)];(2)患
Acquired Immune Deficiency Syndrome (Acqired I-mmunodeficiency syndrome, referred to as AIDS), or “AIDS” is a newly discovered disease in recent years characterized by cellular immune deficiency, resulting in patients with opportunistic infections and malignant tumors. The mortality rate is high. Both adults and children are at risk, with homosexuals and injecting drug users more prevalent. Contagious, but the pathogen is not yet fully confirmed. The disease first appeared in Haiti in the late 1970s. In 1979, cases were reported in New York and California in the United States. In 1981, the CDC formally named the disease AIDS and proposed two criteria for diagnosing the disease: (1) at least moderate to moderate Indications of cellular immunodeficiency [Conditional infection or Raposi’s sarcoma in people under 60 years of age]; (2)
