美国疾病控制中心(CDC)最近的一项研究表明男人和妇女感染AIDS病毒并不总是由其固定的性伴侣传播。但令人惊异的是已感染者与他或她的配偶的性生活频率对于传播病毒的可能性没有明显的关系。异性传播人免疫缺陷病毒(HIV)的机理仍然使医学科学家困惑不解。美国的研究者研究了88个家庭,在这些家庭中丈夫或妻子都因输血而被HIV感染。这些人至少有两年都没有觉察到自己被感染并继继性生活。 80名被感染的配偶(25名
A recent study by the Centers for Disease Control and Prevention (CDC) showed that men and women infected with the AIDS virus are not always transmitted by their regular partners. It is surprising that there is no obvious relationship between the frequency of sexual intercourse with an infected person and his or her spouse for the possibility of transmitting the virus. The mechanism of heterosexual transmission of human immunodeficiency virus (HIV) remains puzzling medical scientists. Researchers in the United States studied 88 families in which husbands and wives were HIV-infected as a result of blood transfusions. For at least two years, these people have not noticed that they have been infected and have sex lives. 80 infected spouses (25
