JULY 2018 WASH BENEFITS STUDIES

Achieving optimal technology and behavioral uptake of single and combined interventions of water, sanitation hygiene and nutrition, in an efficacy trial (WASH benefits) in rural Bangladesh. BMC Trials, July 2018. Rigorous implementation of interventions deployed at large scale in the context of an efficacy trial achieved high levels of technology and behavioral uptake in individual and combined WASH and nutrition intervention households.

WASH Benefits Bangladesh trial: management structure for achieving high coverage in an efficacy trial. BMC Trials, July 2018. The intensive intervention delivery system required for an efficacy trial differs in many respects from the system for a routine program. To implement a routine program at scale requires further research on how to optimize the supervisor-to-CHW-to-intervention household ratios, as well as other program costs without compromising program effectiveness.

WASH Benefits Bangladesh trial: system for monitoring coverage and quality in an efficacy trial. BMC Trials, July 2018. An intensive implementation fidelity monitoring and rapid response system proved beneficial for this efficacy trial. To implement a routine program at scale requires further research into an adaptation of fidelity monitoring that supports program effectiveness.

OPEN ACCESS JOURNAL ARTICLES

A Systematic Review and Meta-Analysis of the Association between Water, Sanitation, and Hygiene Exposures and Cholera in Case–Control Studies. Am Jnl Trop Med Hyg, Early view. Water, sanitation, and hygiene interventions should address multiple transmission routes and be well implemented, according to international guidance, to ensure that field effectiveness matches theoretical efficacy. In addition, future case–control studies should detail WASH characteristics to contextualize results.

Soil‐transmitted helminth infections associated with wastewater and sludge reuse: a review of current evidence. Trop Med Intl Health, July 2018. Epidemiological evidence reveals an increased prevalence of STH infections associated with direct exposure to wastewater or sludge (farmers) and consumption of vegetables grown on soil treated with it.

ABSTRACT/ORDER

Wild waterfowl as potential vectors of Vibrio cholerae and Aeromonas species. Trop Med Intl Health,  July 2018. (Abstract/order) Wild waterfowl species may carry pathogenic V. cholerae O1 and non‐O1 serogroups and Aeromonas species in their intestine. The migration of waterfowl is a potential mechanism for global distribution of V. cholerae and Aeromonas.

UNC WATER INSTITUTE WaSH POLICY RESEARCH DIGESTS

Issue #8, May 2018: Remote Monitoring of Handpump Functionality – The eighth issue of the WaSH Policy Research Digest focuses on remote monitoring of the functionality of rural handpumps.

Issue #7, December 2017: Intermittent Water Supply – The seventh issue of the Digest examines the effects of intermittent water supply. Much of the world’s population is served by piped water that is neither continuous nor reliable, and this jeopardizes water quality, and thus the health of users. It also costs users time and money, and damages water infrastructure. The Digest outlines the successful measures that utilities have put in place to ensure continuous supply.

Issue #6, August 2017: Community Management – The sixth issue of the Digest looks at the topic of community management in rural water supply.  Management of water systems by local communities, once considered standard best practice, has come under fire of late due to its failure to ensure sustainable services in many contexts.
