In Central and South America, enteric infections constitute one of the leading causes of disease and death. The terrible toll is exacted by a host of different microorganisms, virtually all of which are transmitted via contact with human excreta. To change this picture we need many more water supply and sewerage systems, better food preparation and handling, and public comprehension of how elementary good hygiene promotes good health. Attaining these objectives will be difficult, but less costly than one might suppose, and there is little to be gained by delay. The basic enviromental causes of enteric disease are clear, current conditions have been aggravated by rapid population growth and urbanization, and basic corrective measures have already been postponed long enough.
在中美洲和南美洲，肠道感染是导致疾病和死亡的主要原因之一。许多不同的微生物造成了严重的损失，几乎所有这些微生物都是通过接触人类排泄物传播的。为了改变这种状况，我们需要更多的供水和污水处理系统，更好的食品制备和处理方式，以及公众对基本的良好卫生习惯如何促进健康的理解。实现这些目标将很困难，但成本比人们想象的要低，拖延没有任何好处。肠道疾病的基本环境成因很明确，目前的状况因人口快速增长和城市化而加剧，基本的纠正措施已经推迟得够久了。
