Brief Summary

Environmental health-related pathogens include faecal-oral, diarrhoeagenic microbes that may be transmitted via drinking water and are related to sanitation and hygiene. Previous research has suggested that safeguarding household drinking water against recontamination may be a critical intervention that can reduce risks of diarrheal diseases and may be especially important for people living with HIV/AIDS (PLWHA) and other vulnerable populations (Clasen et al. 2007). The investigators propose here a randomised, controlled trial of a household safe storage container for drinking water in a well defined, HIV-impacted population in peri-urban Lusaka, Zambia. After a baseline data collection period (9 months) half of all households (150 households) will be given a safe water storage container specifically designed to prevent recontamination of water in household use. All households will be followed for an additional 9 months. Results of this study will help determine whether this promising water quality intervention can reduce diarrhoea and related outcomes in this and similar vulnerable populations.

Outcome Measures

Primary Outcomes (1)

  • Self-reported diarrheal disease

    Self-reported diarrheal disease information will be collected from each study participant monthly. These data will be collected monthly with 24 hour, 48 hour, and 7-day recall. Data will be assessed at 18 months (change from baseline).

    18 months

Secondary Outcomes (3)

  • Weight-for-age z-score

    18 months

  • E. coli and total coliforms in household drinking water

    18 months

  • Salivary antibody response

    18 months

Study Arms (2)

Safe storage device

EXPERIMENTAL

This arm will be assigned a safe water storage device.

Device: Safe storage device

Control

NO INTERVENTION

This arm of the trial will receive nothing until the end of the trial.

Interventions

This device is a specially designed water storage container that is intended to reduce the likelihood of re-contamination of household stored drinking water.
