The causes of the problem lie in the social, economic, political and cultural exclusion of sectors of the population who are living in poverty, without even basic minimum sanitation services, drinking water, access to health, education or security.
问题的根源是贫困人口阶层在社会、经济、政治和文化上受到排斥，没有最基本的卫生设施，得不到饮用水和保健服务。
