In an earlier study in rural Guatemala, 257 households that received flocculant-disinfectant to treat their drinking water had 39% less diarrhea than 257 control households. Three weeks after completion of the study, national marketing of the flocculant-disinfectant was extended into the study communities. Six months later, we assessed frequency of and(More)
OBJECTIVE To compare the effect on prevalence of diarrhoea and mortality of household based treatment of drinking water with flocculant-disinfectant, sodium hypochlorite, and standard practices in areas with turbid water source in Africa. DESIGN Cluster randomised controlled trial over 20 weeks. SETTING Family compounds, each containing several houses,(More)
We introduced home drinking water disinfection and handwashing with soap in Karachi squatter settlements to evaluate their effect on diarrhea. In April 2000, 150 households received soap, 76 received dilute bleach and a water storage vessel, and 76 were enrolled as controls. In 2000, among households wealthy enough to own a refrigerator, children in(More)
OBJECTIVE To examine the effect of a new point-of-use treatment for drinking-water, a commercially developed flocculant-disinfectant, on the prevalence of diarrhoea in children. METHODS We conducted a randomized controlled trial among 514 rural Guatemalan households, divided into 42 neighbourhood clusters, for 13 weeks, from 4 November 2002 through 31(More)
We conducted a study to determine if soap containing 1.2% triclocarban would be effective in reducing the incidence of impetigo. We randomized 162 households in a low-income neighborhood of Karachi, Pakistan, to receive a regular supply of 1.2% triclocarban-containing soap (n = 81) or an identically appearing placebo (n = 81); 79 households in a nearby(More)
Household-level water treatment products provide safe drinking water to at-risk populations, but relatively few people use them regularly; little is known about factors that influence uptake of this proven health intervention. We assessed uptake of these water treatments in Nyanza Province, Kenya, November 2003-February 2005. We interviewed users and(More)
