AIDS的致病原是一组最近描述的淋巴细胞病逆转录病毒,称为淋巴腺病相关病毒(LAV),人类嗜T淋巴细胞病毒(HTLV-Ⅲ)和ALDS相关逆转录病毒(ARV)。该病的高危人群有男性同性恋、异性恋、静脉药隐者,接受输血或血制品等。受累婴儿占AIDS的1%,常由人群的妇女所生,一小部分婴儿系输血所致。凡母亲是婴儿明显的感染源的病例,所有的报导均一致认为该病可通过宫内传播或在出生过程中被感染。流行病学论证,由于双亲为高危人群组的婴儿感染病例的症状一般较生后接受污染的输血所感染婴儿的症状出现为早,传播是经由胎盘途径。因病毒能从淋巴细胞中分离出来和活的母体淋巴
The causative agent of AIDS is a group of recently described retrovirus lymphotrophic viruses, called lymphotrophic virus (LAV), human troponin (HTLV-III) and ALDS related retroviruses (ARV). The high-risk populations of the disease are gay and lesbian, heterosexual and intravenous drug users who accept transfusions or blood products. Affected infants account for 1% of AIDS, often caused by women in the population, a small proportion of infants due to blood transfusions. Where mothers were the obvious source of infection in infants, all the reports agreed that the disease could be transmitted intrauterineally or during birth. Epidemiological evidence shows that symptoms of infantile infections in groups of high parents at risk are generally earlier than symptoms of infants infected with contaminated blood transfusions after birth and are transmitted via the placenta. Because the virus can be isolated from lymphocytes and living maternal lymph
