尽管在实现联合国艾滋病毒/艾滋病联合规划署95-95-95目标方面取得了进展,但南非仍然是全球艾滋病毒流行最严重的国家之一。在这项研究中,我们生成了高分辨率的艾滋病毒流行率地图,并确定了服务不足地区的艾滋病毒感染者(PLHIV),为艾滋病毒相关服务的优化分配提供了必要的信息。数据来自2016年进行的南非人口与健康调查,空间变量来自其他已发表的文献。我们制作了艾滋病毒流行率和服务不足地区的高分辨率地图,这些地区的定义是距离最近的医疗机构超过30分钟的旅行时间。使用这些地图和人口密度,我们绘制了PLHIV和PLHIV在服务不足的地区为30,60和120分钟的阈值。艾滋病毒流行率存在很大的地域差异,男性从1.4%到24.2%不等,中位数为11.5%,女性从2.1%到48.1%不等,中位数为20.6%。豪登省的艾滋病毒流行率和艾滋病毒感染者密度最高。全国80%的地区被确定为服务不足地区(30分钟阈值),其中男性和女性艾滋病毒感染者分别占16%和20%以上。夸祖鲁-纳塔尔省在服务不足地区(30分钟阈值)的艾滋病毒感染者人数最多,每1 000名艾滋病毒感染者不到一个医疗机构。我们的研究表明,在南非服务不足的地区,艾滋病毒的流行率和大量的艾滋病毒感染者的广泛的空间变化。此外,我们确定了需要加强艾滋病毒相关服务的地点,以覆盖服务不足地区的约150万艾滋病毒感染者,特别是在夸祖鲁-纳塔尔省,每1000名艾滋病毒感染者不到一个医疗机构。
Despite progress towards the Joint United Nations Programme on HIV/AIDS 95-95-95 targets, South Africa is still suffering from one of the largest HIV epidemics globally. In this study, we generated high-resolution HIV prevalence maps and identified people living with HIV (PLHIV) in underserved areas to provide essential information for the optimal allocation of HIV-related services. The data come from the South Africa Demographic and Health Survey conducted in 2016 and spatial variables from other published literature. We produced high-resolution maps of HIV prevalence and underserved areas, defined as a greater than 30 min travel time to the nearest healthcare facility. Using these maps and the population density, we mapped PLHIV and the PLHIV within underserved areas for 30, 60 and 120 min thresholds. There was substantial geographic variation in HIV prevalence, ranging from 1.4% to 24.2%, with a median of 11.5% for men, and from 2.1% to 48.1%, with a median of 20.6% for women. Gauteng province showed the highest density for both HIV prevalence and PLHIV. 80% of all areas in the country were identified as underserved areas (30 min threshold), which contained more than 16% and 20% of the total men and women living with HIV, respectively. KwaZulu-Natal province had the largest number of PLHIV in underserved areas (30 min threshold) and showed less than one healthcare facility per 1000 PLHIV. Our study showed extensive spatial variation of HIV prevalence and significant numbers of PLHIV in underserved areas in South Africa. Moreover, we identified locations where HIV-related services need to be intensified to reach the ~1.5 million PLHIV in underserved areas, particularly in KwaZulu-Natal province, with less than one healthcare facility per 1000 PLHIV.
