We installed drinking water and handwashing stations in 17 rural schools and trained teachers to promote water treatment and hygiene to pupils. We gave schools flocculent-disinfectant powder and hypochlorite solution for water treatment. We conducted a baseline water handling survey of pupils' parents from 17 schools and tested stored water for chlorine. We trained teachers and students about hygiene, installed water stations, and distributed instructional comic books to students. We conducted follow-up surveys and chlorine testing at 3 and 13 months. From baseline to 3-month follow-up, parental awareness of the flocculent-disinfectant increased (49–91%, P < 0.0001), awareness of hypochlorite remained high (93–92%), and household use of flocculent-disinfectant (1–7%, P < 0.0001) and hypochlorite (6–13%, P < 0.0001) increased, and were maintained after 13 months. Pupil absentee rates decreased after implementation by 26%. This school-based program resulted in pupil-to-parent knowledge transfer and significant increases in household water treatment practices that were sustained over 1 year.
A hospital-based surveillance study conducted by Ciara O'Reilly and colleagues describes the risk factors for death amongst children who have been hospitalized with diarrhea in rural Kenya.
Abstract. We conducted a randomized, placebo-controlled, triple-blinded trial to determine the health impact of daily use of sodium dichloroisocyanurate (NaDCC) tablets for household drinking water treatment in periurban Ghana. We randomized 240 households (3,240 individuals) to receive either NaDCC or placebo tablets. All households received a 20-liter safe water storage vessel. Over 12 weeks, 446 diarrhea episodes (2.2%) occurred in intervention and 404 (2.0%) in control households ( P = 0.38). Residual free chlorine levels indicated appropriate tablet use. Escherichia coli was found in stored water at baseline in 96% of intervention and 88% of control households and at final evaluation in 8% of intervention and 54% of control households ( P = 0.002). NaDCC use did not prevent diarrhea but improved water quality. Diarrhea rates were low and water quality improved in both groups. Safe water storage vessels may have been protective. A follow-up health impact study of NaDCC tablets is warranted.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
