Design outcomes

Primary

Measure	Time frame
Diarrhoeal incidence of under-five children (cases /child*weeks). We will conduct a household-based survey 9 times throughout the sanitation-project period, roughly 10 months, meaning that the household survey will be conducted every month. With regards to measuring the outcmes, diarrhoea will not be diagnosed by a laboratory-based test, instead it will be identified by mothers' or caretakers' self report on the basis of a strict definition developed by the WHO expert group. We will help mothers or caretakers record the incidence of diarrhoea on the spot by using a specially-devised calendar, rather than depending on their recall.	—
