Data obtained in a controlled field study over 5 years in 4 communities showed that the provision of sanitary facilities for human waste disposal can reduce the incidence of cholera by as much as 68%, while the provision of a safe water supply can decrease it by 73%. Where both toilets and water supplies are provided, the incidence can be reduced by as much as 76%. There was evidence that cholera infection gaining access to communities with these facilities tends to spread less and produce fewer secondary cases than in a community where such facilities are not provided.
在4个社区进行的一项为期5年的对照实地研究中获得的数据表明，提供用于处理人类排泄物的卫生设施可将霍乱发病率降低多达68%，而提供安全的供水可将其降低73%。如果同时提供厕所和供水，发病率可降低多达76%。有证据表明，与未提供此类设施的社区相比，霍乱感染进入有这些设施的社区后往往传播得更少，产生的二代病例也更少。
