Water, sanitation, and hygiene interventions can interrupt diarrhoeal disease transmission and reduce the burden of morbidity and mortality associated with faecal-oral infections. We know that rapid response of effective WASH infrastructure and services can prevent or lessen the impact of diarrhoeal outbreaks that can exacerbate the human suffering accompanying humanitarian crises. In this review summary, we present an overview of current knowledge about what works to prevent disease in emergency WASH response.

Adherence to Point-of-Use Water Treatment over Short-Term Implementation: Parallel Crossover Trials of Flocculation Disinfection Sachets in Pakistan and Zambia

The health benefits of point-of-use (POU) water treatment can only be realized through high adherence: correct, consistent, and sustained use. We conducted parallel randomized, longitudinal crossover trials measuring short-term adherence to two single-use flocculant–disinfectant sachets in Pakistan and Zambia. In both trials, adherence declined sharply for both products over the eight week surveillance periods, with overall lower adherence to both products in Zambia. There was no significant difference in adherence between the two products.
