To assess the contamination level of total and faecal coliforms in water wells and distribution networks, and their association with human health in Gaza Governorate, Gaza Strip.
Data were obtained from the Palestinian Ministry of Health on contamination of total and faecal coliforms in water wells and distribution networks, and on the incidence of water-related diseases in Gaza Governorate. An interview questionnaire was conducted with 150 residents of Gaza.
The contamination level of total and faecal coliforms exceeded that of the World Health Organization (WHO) limit for water wells and networks. However, the contamination percentages in networks were higher than that in wells. Giardiasis was strongly correlated with faecal coliform contamination in water networks (r=0.7) compared with diarrhoeal diseases and hepatitis A (r=0.3 and 0.1, respectively). Diarrhoeal diseases were the highest self-reported diseases among interviewees in Gaza city. Such diseases were more prevalent among people using municipal water than people using desalinated water and water filtered at home for drinking (OR=1.6). Intermittent water supply and sewage flooding seemed to contribute largely to self-reported diseases. People in Gaza Strip have good knowledge on drinking water contamination, and this is reflected in good practice.
Water quality has deteriorated in Gaza Strip. This may contribute to the prevalence of water-related diseases. Self-reported diseases among interviewees in Gaza City were associated with source of drinking water, intermittent water supply, sewage flooding and age of water, and wastewater networks.
评估加沙地带加沙省水井和配水网络中总大肠菌群和粪大肠菌群的污染水平，及其与人类健康的关联。
从巴勒斯坦卫生部获取有关水井和配水网络中总大肠菌群和粪大肠菌群污染情况以及加沙省水传播疾病发病率的数据。对150名加沙居民进行了访谈问卷调查。
水井和网络中总大肠菌群和粪大肠菌群的污染水平超过了世界卫生组织（WHO）的水质标准。然而，网络中的污染百分比高于水井。与腹泻疾病和甲型肝炎（分别为r = 0.3和0.1）相比，贾第虫病与水网络中的粪大肠菌群污染密切相关（r = 0.7）。腹泻疾病是加沙市受访者中自我报告最多的疾病。此类疾病在使用市政供水的人群中比使用淡化水和在家过滤饮用水的人群中更为普遍（比值比= 1.6）。间歇性供水和污水泛滥似乎在很大程度上导致了自我报告的疾病。加沙地带的人们对饮用水污染有很好的认识，这体现在良好的行为习惯上。
加沙地带的水质已经恶化。这可能导致水传播疾病的流行。加沙市受访者中的自我报告疾病与饮用水来源、间歇性供水、污水泛滥、水龄以及污水网络有关。
