TL;DR: Water quality interventions (point-of-use water treatment) were found to be more effective than previously thought, and multiple interventions (consisting of combined water, sanitation, and hygiene measures) were not moreeffective than interventions with a single focus.

TL;DR: The burden of diarrhoeal diseases from exposure to inadequate water, sanitation and hand hygiene in low‐ and middle‐income settings and an overview of the impact on other diseases are estimated.

TL;DR: To assess the impact of inadequate water and sanitation on diarrhoeal disease in low‐ and middle‐income settings, a large number of patients in low- and middle-income settings are exposed to faeces-based infectious diseases.

TL;DR: To estimate the global prevalence of handwashing with soap and derive a pooled estimate of the effect of hygiene on diarrhoeal diseases, based on a systematic search of the literature.

TL;DR: Numerical microbiological criteria for intestinal enterococci are proposed in the new Guidelines using a novel approach to disease burden assessment, which has been applied to both recreational waters and urban air quality.
