Prevalence of Diarrhea at the Household Level

The reason for including this indicator is the strong link between diarrhea as a WASH-related disease which causes morbidity (and can lead to mortality). This indicator will measure the number of self-reported cases of diarrhea at the household level at the point of baseline and endline. The household survey question will ask respondents if there has been any case of diarrhea within the household within the past two weeks. Survey enumerators will be able to explain the term ‘diarrhea’ to ensure consistency across all surveys. Recognising the potential challenges in accuracy of self-reported data, you should also consider collecting data from Health Centers at baseline and endline to triangulate the information. However, note the following issues with relying solely on health center data: - number going to health centers may increase because of increased income available to spend on health care - number going to health centers may decrease because people are now aware of how to treat diarrhea at home.

Suggested Data Collection Method: This indicator will be measured through a statistically significant and representative household survey conducted at baseline and endline; the purpose is to assess whether there have been any cases of diarrhea within the household within the previous two weeks.  This can be triangulated with data collected from Health Centres present in the areas where the surveys are conducted (see caveat under "definitions")
Numerator:  Total number of cases of diarrhea within households within the previous 2 weeks self-reported at endline
Denominator: Total number of cases of diarrhea within households within the previous 2 weeks self-reported at baseline
Number of cases of diarrhea within households self-reported for both numerator and denominator.  Both numerator and denominator are reported as well as the percentage.

RECOMMENDED SURVEY QUESTIONS (Q) AND POSSIBLE ANSWERS (A)

Ensure you collect Household demographic information in order to be able to disaggregate data by sex, age, and disability factors.
Q1 - in the past two weeks, has there been a case of diarrhea in your household?
A - yes / no / don't know
If in the past two weeks has there been a case of diarrhea in y our household? is any of Yes
Q2 how many people in your family experienced diarrhea in the past two weeks?
Ensure the Answer responses to this question is set up by way of a matrix which uses the same gender/age brackets as the demographic questions at the start of the survey
You may want to consider adding additional questions, to explore whether people's knowledge on what causes diarrhea, and how they treat diarrhea has changed between baseline and endline (collecting data at baseline is a good way to design your intervention to address knowledge and practice)

Sex and age 

Note this indicator is measuring the PERCENTAGE REDUCTION - not actual percentages - so set your target appropriately.
