在非洲成人中人类免疫缺陷病毒(HIV)的传播主要是在异性恋者之间。对中非患艾滋病(AIDS)病人的最初研究发现妓女及与异性乱交的男性是高危人群。对金沙萨(扎伊尔),布科巴(坦桑尼亚),内罗毕(肯尼亚),布塔雷(卢旺达)等地的妓女进行血清学调查,发现27～88%HIV 抗体阳性。在肯尼亚和卢旺达,对妓女、嫖客或患性传播疾病(STDs)的男性同时进行了调查,发现妓女组的HIV 抗体检出率比其他组至少高2～3倍。这提示妓女是传播HIV 的重要来源。STDs 在非洲许多国家流行,可能对HIV 的传播是一个促进因素。对肯尼亚最初血清阴性的妓女所进行的前瞻性研究中,发现血清HIV 抗体转为阳性者与一次或是多次发作的生殖器溃疡病有关。对患STDs 的男性及近期内与妓女有过性接触的男性
The spread of human immunodeficiency virus (HIV) among adults in Africa is mainly between heterosexuals. Initial studies of patients with AIDS in Central Africa have found that prostitutes and men with heterosexual promiscuity are at high risk. A serological survey of prostitutes in Kinshasa (Zaire), Bukoba (Tanzania), Nairobi (Kenya), Butare (Rwanda) found 27-88% of HIV antibody positive. In Kenya and Rwanda, prostitutes, clients or men with sexually transmitted diseases (STDs) were surveyed at the same time. The detection rate of HIV antibody in the prostitute group was at least 2 to 3 times higher than that in other groups. This suggests that prostitutes are an important source of HIV transmission. STDs are prevalent in many African countries and may be a contributing factor to the spread of HIV. In a prospective study of the first seronegative prostitutes in Kenya, it was found that the conversion of serum HIV antibody to positive was associated with one or more episodes of genital ulcer disease. Men with STDs and men who have had sexual contact with prostitutes in the near future
