CI = confidence interval; PR = prevalence ratio for detection of enteric pathogen in stool specimen.

^*N = 76 children from which stool specimens were collected (43 in Chinnallapuram, 33 in Old Town). Enteric pathogens detected in stool specimens included astrovirus, Campylobacter spp., Entamoeba histolytica, Giardia spp., genotype II norovirus, and pathogenic E. coli. A full list of organisms tested in stool specimens is presented in Houpt and others.²⁹ Only pathogens detected in > 20% of stool specimens were regressed against neighborhood and hygiene status.

^†Enteroaggregative E. coli, enterohemorrhagic E. coli, enteropathogenic E. coli, and enterotoxigenic E. coli.
