TL;DR: The evidence is nonetheless strong enough to support the provision of water supply, sanitation and hygiene for all, and the striking effect of handwashing with soap is consistent across various study designs and pathogens, though it depends on access to water.

TL;DR: There is some evidence that interventions to improve excreta disposal are effective in preventing diarrhoeal disease, but the quality of the evidence is generally poor and does not allow for quantification of any effect.

TL;DR: The purpose of this paper is to explain how mathematical programming can be used to optimize EPI and other household survey sampling methods in situations where sample frames are either unavailable or are unreliable.

TL;DR: People with disabilities may not have poorer access to WASH at the household level, but may have poorer quality of access within their households, as well as more marked for people with more severe impairments.

TL;DR: This special issue of Emerging Themes in Epidemiology is entirely devoted to survey methods in such settings, and builds upon a successful conference in London highlighting problems with current approaches and possible ways forward.
