获得性免疫缺陷综合征(acquired Immunodeficiency syndrome,AIDS)简称艾滋病,是由人类免疫缺陷病毒(human Immunodeficiency virus,HIV)感染引起的严重的细胞免疫功能缺陷的疾病。病毒主要侵犯、破坏辅助性T淋巴细胞(CD4+T淋巴细胞),使机体细胞免疫功能受损,最后并发各种严重的机会性感染和肿瘤导致死亡。卡波西肉瘤(KS)是HIV/AIDS病人机会性肿瘤
Acquired Immunodeficiency syndrome (AIDS) is a disease of severe cellular immune deficiency caused by human immunodeficiency virus (HIV) infection.
