Facilitating handwashing where water is scarce – EAWAG

Facilitating handwashing where water is scarce – EAWAG, October 22, 2018.

Even though the water we’ve used for washing our hands is barely contaminated, it usually disappears down the drain, never to be used again. A newly developed system allows handwashing water to be recycled, thus not only saving water, but also helping to prevent infectious diseases in developing countries. eawag

Every year, according to WHO figures, around four million people die as a result of diarrhoeal diseases or respiratory infections. Particularly in developing countries, these deaths are largely attributable to poor hygiene – the problem would be significantly alleviated by regular handwashing.

But how can this be achieved in places where people lack access to safe water, or piped water is unavailable? This issue is being addressed by a group of environmental engineers led by ETH Professor Eberhard Morgenroth (Head of Process Engineering at Eawag), carrying out research as part of the Blue Diversion AUTARKY project.

They have now developed a grid-free treatment system allowing greywater – relatively clean wastewater from showering, bathing or handwashing – to be repeatedly recycled.

As Morgenroth points out, while commercial systems are already available which enable greywater to be treated on-site for use in toilet flushing, the recycled water does not meet the required quality standards to be used for other purposes.

Development and Application of Novel Caregiver Hygiene Behavior Measures Relating to Food Preparation, Handwashing, and Play Environments in Rural Kenya

Development and Application of Novel Caregiver Hygiene Behavior Measures Relating to Food Preparation, Handwashing, and Play Environments in Rural KenyaInt. J. Environ. Res. Public Health 201815(9), 1994; https://doi.org/10.3390/ijerph15091994

Exposure to fecal pathogens results in both acute and chronic sequalae in young children. Diarrhea causes nearly 20% of all under-five mortality, while even sub-clinical enteric infections may lead to growth shortfalls. Stunting affects nearly 165 million children globally and results in lifelong and intergenerational effects for the world’s poorest populations. ijerph-logo

Caregiver hygiene behaviors, such as those surrounding handwashing and food preparation, play a critical role in exposure to fecal pathogens; standard metrics to assess these behaviors are warranted to provide a means of quantifying the impact these behaviors have on enteric infections and to evaluate the success or failure of interventions and programs.

This paper documents the development of three novel caregiver hygiene behavior measures: hygienic food preparation and storage, handwashing at key times, and provision of a safe play environment for children under two years.

We developed these measures using formative qualitative work, survey creation and deployment theoretically underpinned by the COM-B model of behavior change, and exploratory and confirmatory factor analysis.

The final measure for hygienic food preparation and storage includes 10 items across two factors; the final measure for handwashing at key times includes 15 items across three factors; and the final measure for safe play environment contains 13 items across three factors.

Future researchers may employ these measures to assess caregiver behaviors in other populations, identify specific behavioral dimensions that should be the focus of interventions, and evaluate interventions and programs

Webinar summary: The forgotten juncture? Handwashing and safe management of child feces

On August 22nd, 2018, the Global Handwashing Partnership, in conjunction with USAID, the International Water Center, the Water and Engineering Center for Development, and UNICEF hosted a discussion on the intersection of handwashing and the safe management of child feces. ghp

Safe disposal of children’s feces is a critical practice, and programs often under-emphasize critical times for handwashing related to infant and child feces. This webinar aimed to:
• Discuss the present status and impact of child feces disposal practices and handwashing,
• Highlight case studies, interventions and evidence,
• Share experiences across regions; and
• Review key considerations for practitioners.

UNICEF Regional WASH Innovation Challenge

We are delighted to share with you details of the Regional WASH Innovation challenge which UNICEF recently launched in partnership with BRAC and ask your support in sharing the contacts and details throughout your sectors and networks.

This year the focus is on handwashing – looking for innovative ways to get Mothers and caregivers to wash their hands with soap at critical times. washinnovation

HANDWASHING + SOAP = SAVED LIVES – If it’s simple in theory why is it so hard to practice?

This challenge is open to applicants from all countries in South Asia and there is a $5,000 prize for each of the three categories, full details and applications can be made through the following links and I have also included some specific details in the text below.

The closing date is September 10, 2018 – so please join us on facebook, twitter and Instagram and visit our website. But most importantly help us spread the word about this important challenge so that we can solve the equation and save more lives through improved handwashing.

Regional WASH Innovation Challenge

Purpose and Problems to be addressed by the Challenge – The purpose of the Regional WASH Innovation Challenge will be to identify innovative solutions to promote handwashing with soap that can be implemented to scale in the South Asia region. The promotion will focus on:

  • Improving education and awareness of handwashing with soap, identifying the benefits of using soap, understanding of proper handwashing techniques and critical times for handwashing; and
  • Behaviour change, resulting in and sustaining the increase of good practice of handwashing with soap using proper techniques and at critical times;
  • Health impact where the incidence of diarrhoeal diseases and respiratory infections is reduced, improving children’s health and mitigating the risk of preventable child deaths.

Hand Hygiene and Sepsis Prevention – Water Currents

Hand Hygiene and Sepsis Prevention – Water Currents, May 15, 2018

May 5, 2018 marked World Hand Hygiene Day, an annual awareness day and call to action for promoting hand hygiene in health care.

This year’s theme was “It’s in your hands—prevent sepsis in health care.” Sepsis—when the body’s response to infection causes injury to its own tissues and organs—affects more than 30 million patients every year worldwide and leads to an estimated 6 million deaths. handhygiene

Proper hand hygiene is a critical step to preventing sepsis and providing quality health care.

This issue contains recently published studies on hand hygiene, as well as studies on water and sanitation conditions in health care facilities (HCFs).

We would like to thank the Global Handwashing Partnership (GHP) for contributing to this issue. GHP is a coalition of international stakeholders working to promote handwashing with soap as a pillar of international development and public health.

Objectives – Safe drinking water, sanitation and hygiene are protective against diarrhoeal disease; a leading cause of child mortality. The main objective was an updated assessment of the impact of unsafe water, sanitation and hygiene (WaSH) on childhood diarrhoeal disease.

Methods – We undertook a systematic review of articles published between 1970 and February 2016. Study results were combined and analysed using meta-analysis and meta-regression.

Results – A total of 135 studies met the inclusion criteria. Several water, sanitation and hygiene interventions were associated with lower risk of diarrhoeal morbidity.

  • Point-of-use filter interventions with safe storage reduced diarrhoea risk by 61% (RR=0.39; 95% CI: 0.32, 0.48);
  • piped water to premises of higher quality and continuous availability by 75% and 36% (RR=0.25 (0.09, 0.67) and 0.64 (0.42, 0.98)), respectively compared to a baseline of unimproved drinking water;
  • sanitation interventions by 25% (RR=0.75 (0.63, 0.88)) with evidence for greater reductions when high sanitation coverage is reached; and interventions promoting handwashing with soap by 30% (RR=0.70 (0.64, 0.77)) versus no intervention.
  • Results of the analysis of sanitation and hygiene interventions are sensitive to certain differences in study methods and conditions. Correcting for non-blinding would reduce the associations with diarrhoea to some extent.

Conclusions – Though evidence is limited, results suggest that household connections of water supply and higher levels of community coverage for sanitation appear particularly impactful which is in line with targets of the Sustainable Development Goals.
