Association between levels of human and of animal fecal contamination of exposure pathways^a detected in the home and household under-5 child diarrhea prevalence^b within 6 weeks after sampling.

Tested variables	Number of households	Odds ratio	95% CI		p-value
Level of human fecal contamination in a household:
All pathways (sample types)c negative for human fecal marker	110	Ref.			0.044
Some pathways positive for human fecal marker	53	1.52	0.52	4.43	0.44
All pathways were positive for human fecal marker	11	4.18	1.3	13.46	0.02
Level of animal fecal contamination in a household:
All pathways (sample types)c negative for animal fecal marker	28	Ref.			0.013
Some pathways positive for animal fecal marker	92	1.58	0.42	5.97	0.50
All pathways positive for animal fecal marker	54	4.54	1.17	17.59	0.03

^aThree levels of contamination were defined: (1) all 3 pathways (i.e. sample types: SDW, mother's HR, child HR) were negative, (2) some but not all were positive, or (3) all were positive. Human and animal fecal contamination was measured by the BacHum and BacCow assays, respectively.

^bHousehold 7-day recall period prevalence for under-5 child diarrhea observed in the Sanitation Trial (Clasen et al., 2014) measured between 1 and 6 weeks after domestic domain environmental sampling for MST markers in the household.

^cStored drinking water (SDW), mother's hands (mother's HR), and children's hands (child HR).
