艾滋病(AIDS)是获得性免疫缺陷综合征的简称。自从1981年首先在美国发现以后,报道的病例日益增多。目前,全世界报道的病例已超过70000例,分布50余国家.其中半数以上已死亡。成为最严重的世界性公共卫生问题。在1986年召开的世界病毒学会上,对AIDS病进行了专题讨论,并建议以后AIDS病毒称为人类免疫缺陷病毒(HIV)。感染这种病毒后,可有3种不同表现:(1)AIDS病,约为感染者的5～20％。大都于5年内因各种机遇性感染而死亡;(2)AIDS相关综合征,约为AIDS人数的2～7倍,表现为一系列的淋巴结病伴一组症候群,如发热、疲乏、食欲不振、消瘦、腹泻等。这类病人是AIDS的轻型病例.其中部分病例进一步发展为AIDS,部分病例则停留于此期:(3)隐性感染,约占感染者的50～70%,无任何临床症状,但是病毒的携带者。其中部
AIDS is the abbreviation of Acquired Immune Deficiency Syndrome. Since the first discovery in the United States in 1981, there have been an increasing number of reported cases. At present, there are more than 70,000 cases reported worldwide, covering more than 50 countries, of which more than half have died. Become the world’s most serious public health problem. At the World Association for Virology held in 1986, there was a thematic discussion on AIDS and suggested that the AIDS virus be called the human immunodeficiency virus (HIV) later. Infection with this virus, there are 3 different manifestations: (1) AIDS disease, about 5 to 20% of infected persons. Most of them died of various opportunistic infections within 5 years; (2) AIDS-related syndrome, which is about 2 to 7 times of AIDS population, is characterized by a series of syndromes of lymphadenopathy such as fever, fatigue, loss of appetite , Weight loss, diarrhea and so on. These patients are light-weight cases of AIDS, of which some cases further develop AIDS, some cases remain in this period: (3) latent infection, accounting for about 50 to 70% of infected persons, without any clinical symptoms, but the virus Carrier.
