与大多数国家一样，人们对南非人类免疫缺陷病毒（HIV）的地理分布知之甚少。根据 2003 年进行的全国艾滋病毒家庭调查数据，使用广义线性空间模型和贝叶斯预测对 15-24 岁人群的艾滋病毒感染变化进行建模和绘制，该调查包括从全国人口普查中随机抽取的约 700 个普查区的 11,904 名青少年。这些地图显示了各省内艾滋病毒感染率的巨大差异。西开普省内陆农村地区的含量最低，夸祖鲁纳塔尔省西北部、姆普马兰加省南部和自由邦东部地区含量最高。艾滋病毒的流行与种族、城市地位和失业有关。艾滋病毒流行率的详细地图可以有效地用于指导干预计划并将其重点放在有特殊需要的领域。
In common with most countries, little is know about the geographic distribution of human immunodeficiency virus (HIV) in South Africa. Variations in HIV infection of persons 15-24 years of age were modeled and mapped using generalized linear spatial models and Bayesian prediction based on data from a national HIV household survey conducted in 2003 and comprising 11,904 youth from approximately 700 enumeration areas that were randomly selected from the national census. The maps show considerable variation in HIV prevalence within provinces. The lowest levels were found in inland rural areas of the Western Cape, and the highest in northwestern parts of KwaZulu Natal, southern Mpumalanga, and eastern Free State. Prevalence of HIV was associated with ethnicity, urban status, and unemployment. Detailed maps of HIV prevalence can be effectively used in guiding and focusing intervention programs to areas of particular need.
