这是一种慢性致死性传染病,由人类免疫缺陷病毒(Human Immunodeficiency Virus, HIV)引起。HIV感染后导致人体免疫机能缺陷,从而发生机会性感染等一系列临床综合征,病死率几乎达100% HIV属于反转录病毒科,慢病毒属,灵长类免疫缺陷亚属。现已证实HIV分为两型:HIV-1型和HIV-2型,它们又有各自的亚型。不同地区流行的亚型不同,同一亚型在不同地区也存在一定差异。
AIDS is a highly dangerous infectious disease caused by HIV infection (HIV). HIV is a virus that can attack the human immune system.
艾滋病是一种危害性极大的传染病,由感染艾滋病病毒(HIV)引起。HIV是一种能攻击人体免疫系统的病毒。
It takes the most important CD4 T lymphocytes in the human immune system as the main attack target, destroys the cells in large quantities, and makes the human body lose immune function.
它把人体免疫系统中最重要的CD4T淋巴细胞作为主要攻击目标,大量破坏该细胞,使人体丧失免疫功能。
Therefore, the human body is easy to be infected with various diseases, malignant tumors can occur, and the mortality is high.
因此,人体易于感染各种疾病,并可发生恶性肿瘤,病死率较高。
The incubation period of HIV in the human body is 8~9 years on average. In the incubation period of HIV, it can live and work without symptoms for many years.
HIV在人体内的潜伏期平均为8~9年,在艾滋病病毒潜伏期内,可以没有任何症状地生活和工作多年。
