Abstract

This study was undertaken to highlight the social disparity between rural and urban areas in terms of housing patterns, provision of safe drinking water, access to sanitation facilities, education, employment rate and health-related to diarrhoeal episodes in Ugu District Municipality of KwaZulu-Natal Province of South Africa. To achieve this aim, a survey was conducted using a structured questionnaire. Drinking water samples were collected from the point of supply and the storage containers to assess the microbiological quality of drinking water in both rural and urban areas. Results of this study revealed prominent residential segregation between rural and urban communities, whereby the houses in the rural areas were generally constructed with corrugated iron sheets, or mud brick and mortar whereas conventional brick-and-mortar construction was used to build those in the urban areas. All of the urban households had flush toilets in their houses (100%), while 98.2% of the rural households were relying on pit latrines and 1.8% were reported to defecate in an open field. The District unemployment rate was at 58.1% in rural areas and none among the urban community. Results also showed that only 13.6% of the rural dwellers completed their secondary education compared to 70.4% of the urban areas. The diarrhoeal episodes were high in rural areas (34.1%) while none of these episodes was reported in urban areas. Great disparity in the water supply persists between rural and urban communities. For the former, the standpipes located outside their homes (90.9%) remain the sole mode of access to drinking water, while in the urban area, all households had pipes/taps inside their houses. Assessment of the drinking water quality revealed only the stored drinking water used by the rural community of Ugu District was contaminated. High prevalence of ranging from 63.3 % to 66.7% was recorded only in stored water after the sequencing of 16S rRNA genes. Species-specific PCR primers exposed the presence of enteropathogenic at a rate ranging between 1.4% and 3.7% in this water Overall, this study has been able to highlight the disparity left by the legacy of racial segregation in the Ugu Municipality District. Therefore, the local government must intervene in educating homeowners on safe water storage practices.

摘要

本研究旨在强调南非夸祖鲁-纳塔尔省乌古地区在住房模式、提供安全饮用水、获得卫生设施、教育、就业率以及与腹泻发作有关的健康等方面的城乡差距。为了实现这一目标,采用了问卷调查的方法进行了调查。从供水点和储存容器中采集饮用水样本,以评估城乡地区饮用水的微生物质量。本研究结果显示,城乡社区之间存在明显的居住隔离,农村地区的房屋通常由波纹铁皮、土坯和灰浆建造,而城市地区则采用传统的砖石结构建造。城市地区所有家庭的房屋都有冲水马桶(100%),而 98.2%的农村家庭依赖坑式厕所,1.8%的家庭报告在野外排便。该地区农村地区的失业率为 58.1%,而城市社区没有。研究结果还表明,只有 13.6%的农村居民完成了中学教育,而城市地区这一比例为 70.4%。农村地区的腹泻发作率较高(34.1%),而城市地区没有报告这些发作。农村和城市社区的供水差距仍然很大。对于前者,位于他们家外的水龙头(90.9%)仍然是他们获取饮用水的唯一途径,而在城市地区,所有家庭的房屋内都有管道/水龙头。饮用水质量评估显示,只有乌古地区农村社区储存的饮用水受到污染。在对 16S rRNA 基因进行测序后,仅在储存水检测到 63.3%至 66.7%的高流行率。在该水中,种特异性 PCR 引物暴露了致病性 的存在率在 1.4%至 3.7%之间。总体而言,本研究能够突出乌古地区种族隔离遗留下来的差距。因此,地方政府必须介入,教育房主安全储水的做法。
