An exciting and new water treatment breakthrough has been announced that will now make the removal of fluoride from the drinking water supplies of the world’s poorest people more affordable than ever.

Researchers from Rajasthan University in India have discovered that the Tulsi plant, also known as Holy Basil, can be used to significantly reduce the amount of fluoride in drinking water. 

At present, the most reliable methods used to remove excessive fluoride from drinking water are either too expensive or not suitable for the environments where they are needed most.

The method discovered by researchers from Rajasthan University is safe, cheap and readily available, making it an ideal alternative for communities who can’t afford to use the more advanced techniques of removing fluoride that are readily available in the West.

Unsafe drinking water continues to burden developing countries despite improvements in clean water delivery and sanitation, in response to Millennium Development Goal 7. Salmonella serotype Typhi and Vibrio cholerae bacteria can contaminate drinking water, causing waterborne typhoid fever and cholera, respectively. Household water treatment (HWT) systems are widely promoted to consumers in developing countries but it is difficult to establish their benefits to the population for specific disease reduction.

This research uses a laboratory assessment of halogenated chlorine beads treating contaminated water to inform a quantitative microbial risk assessment (QMRA) of S. Typhi and V. cholerae disease in a developing country community of 1000 people. Laboratory challenges using seeded well water resulted in log10 reductions of 5.44 (± 0.98 standard error (SE)) and 6.07 (± 0.09 SE) for Salmonella serotype Typhimurium and V. cholerae, respectively. In well water with 10% sewage and seeded bacteria, the log10 reductions were 6.06 (± 0.62 SE) and 7.78 (± 0.11 SE) for S. Typhimurium and V. cholerae, respectively.

When one infected individual was contributing to the water contamination through fecal material leaking into the water source, the risk of disease associated with drinking untreated water was high according to a Monte Carlo analysis: a median of 0.20 (interquartile range [IQR] 0.017-0.54) for typhoid fever and a median of 0.11 (IQR 0.039-0.20) for cholera. If water was treated, risk greatly decreased, to a median of 4.1 × 10(-7) (IQR 1.6 × 10(-8) to 1.1 × 10(-5)) for typhoid fever and a median of 3.5 × 10(-9) (IQR 8.0 × 10(-10) to 1.3 × 10(-8)) for cholera. Insights on risk management policies and strategies for public health workers were gained using a simple QMRA scenario informed by laboratory assessment of HWT.

Using Tablets in Rural India to Build Demand for Safe Water: A Hi-Tech Approach to Promoting Good Health | Source: by Safe Water Network, Sacramento Bee, May 20, 2013 |

Safe Water Network announced today the launch of its innovative Tablet-based water and health education campaign designed to build awareness of and demand for safe water in rural communities. In one of the first applications of this technology in such a setting, the campaign uses multiple regional dialects and culturally specific marketing content to educate community members on the benefits of safe water and its link to good health. This work is supported by Merck Foundation and builds upon a long-term partnership with Safe Water Network to accelerate the adoption and usage of safe water for drinking and cooking.

“At Merck, we are interested in understanding how innovation can be used to improve global health,” says Danielle Menture, vice president of Global Safety & the Environment at Merck. “This initiative is an excellent example of a new way to use technology to improve access to clean water.” 

Global health experts have been calling for an increased focus on behavior change for many years. Dr. Aidan Cronin, a Water, Sanitation and Hygiene Specialist at UNICEF India, recently stated, “UNICEF realizes the importance of creating awareness about safe drinking water and its multiple benefits.” Dr. Cronin views the Safe Water Network campaign as an important step forward. “In the midst of technology’s growing reach,” he says, “the Tablet campaign is an innovative program that will make people aware about water safety.”

The Tablet approach delivers standardized content which ensures that important messaging remains consistent across users and regions. According to MARI and ECO-Club, Safe Water Network’s local partners in the field, delivering safe water and hygiene messaging on a Tablet is creating a high level of excitement in rural communities. “The enthusiasm I’m met with in the village when using the Tablet allows me to connect with people quickly and hold their attention longer,” says Vedanta from MARI. “The Tablet symbolizes technology and progress; it creates a connection with their urban cousins.”

USAID and Dispensers for Safe Water Announce $5.5 million Partnership

USAID and Dispensers for Safe Water Announce $5.5 million Partnership

by Alexandra Fielden

Women in the remote village of Markuny in Kenya are taking the lead and treating their families’ drinking water. This was not always the case; Markuny used to be one of the many places in the world where waterborne diseases are commonplace. Globally, diarrheal disease is the second leading cause of death in children under five.

To address the global challenge of sickness from cholera, diarrhea and typhoid, Innovations for Poverty Action developed the chlorine dispenser system – a low-cost technology proven to dramatically increase rates of household water treatment, decreasing the burden of waterborne disease.  Today, USAID’s Administrator, Rajiv Shah, announced an award from USAID’s Development Innovation Ventures (DIV) to support the scale-up of the Dispensers for Safe Water program. The $5.5 million grant, supported by DIV’s WASH for Life partnership with the Bill and Melinda Gates Foundation, is DIV’s first Stage 3 award. Stage 3 funding is reserved for innovative solutions that have credible and rigorous evidence of development impacts at significant scale. Stage 3 projects transition an innovation from large scale implementation to widespread adoption; this grant will help Dispensers for Safe Water provide five million people with access to dispensers. 

Chlorine dispensers are installed next to communal water sources, and supported by community education activities to encourage use, and a consistent supply of chlorine. To treat their water, community members simply turn the valve to release a metered dose of chlorine, then fill their container as they normally would with water from the source. The chlorine disinfects the water and provides ongoing protection from recontamination for up to 72 hours.

The dispenser allows community members to conveniently and easily treat their water, and its physical presence provides a visual reminder to do so.  A randomized trial in Western Kenya found 50 – 61% of households in the treatment group adopted the water treatment, compared with only 6 – 14% in the control group. Impressively, the program has been able to maintain high usage, seeing 43% adoption rates at scale.

Director of Programs for Dispensers for Safe Water, Eric Kouskalis, said “we are thrilled to be partnering with DIV on the scale-up of dispensers. DIV’s objective is to find, test, and scale interventions that get the biggest bang for the buck, and at a cost of less than $0.50 per person per year at scale, dispensers fit the bill perfectly.”

Dispensers for Safe Water critically evaluates the program to drive improvements throughout the expansion. DIV and Dispensers for Safe Water will measure success along metrics such as the number of dispenser users (by gender), the percentage of households with chlorine present in their drinking water, the percentage of individuals who understand the benefits and correct usage of dispensers, and the dispenser manufacturing and chlorine delivery costs. This data will provide valuable feedback to help the program maximize adoption, sustain dispenser usage, and increase operational efficiencies.

Maura O’Neill, Chief Innovation Officer at DIV, congratulated DSW on the award. “Results based on rigorous evidence is the hallmark of DIV. Through this award with Dispensers for Safe Water, we will avert 3.3 million cases of diarrhea, save 3,200 children’s lives and that is just in the first three years.”

UNICEF – Cholera Toolkit 2013

May 17, 2013 · 0 comments

To tackle the alarming resurgence of cholera, UNICEF has launched a new comprehensive Cholera Toolkit on 15 May 2013.

The toolkit launch [...] will be the culmination of a thorough review of existing guidance and global consultation with UNICEF at all levels and from all divisions in Africa, along with main partners in the fight against cholera, such as the World Health Organization as the lead agency.

There are 3-5 million cholera cases each year, killing 100,000 to 120,000 people, half of whom are children under 5 years old. Only 5-10% of cases are reported. In Western and Central Africa, there were more than 80,000 cases of cholera in 2012 resulting in nearly 1,500 deaths.

The Toolkit provides the health and WASH sectors an integrated approach to cholera prevention, preparedness and response. In addition it includes specific content linked to education, nutrition, communication for development (C4D), child protection and other relevant sectors.

Prevalence of rotavirus and adenovirus associated with diarrhea

May 15, 2013 · 0 comments

Prevalence of rotavirus and adenovirus associated with diarrhea among displaced communities in Khartoum, Sudan. BMC Infectious Diseases 2013, 13:209.

Wafa I Elhag, et al.

Background – Diarrheal diseases represent a major worldwide public health problem particularly in developing countries. Each year, at least four million children under five years of age die from diarrhea. Rotavirus, enteric adenovirus and some bacterial species are the most common identified infectious agents responsible for diarrhea in young children worldwide. This study was conducted to determine prevalence of rotavirus and adenovirus associated with diarrhea among displaced communities in Khartoum state, Sudan.

Methods – A total of seven hundred and ten patients, children and adults, suffering from diarrhea were examined. The clinical history, socio-demographic characteristics, physical examination findings and laboratory investigations were recorded. Stool samples or rectal swabs were collected and tested for rotavirus and adenovirus antigens using the immuno-chromatography test (ICT). Characterization of the identified Rotaviruses, as a major cause of diarrhea, was then made using real time-reverse transcription PCR. To make the study legal, an ethical clearance was obtained from Sudan Ministry of health- Research Ethical Committee. Written consent was taken from adult subjects, and also from children mothers. The participants were informed using simple language about the infection, aim of the research and the benefits of the study.

Results – Out of the 710 patients, viral pathogens were detected in only 99 cases (13.9%). Of the 99 cases of viral diarrhea, 83 (83.8%) were due to rotaviruses while 16 (16.2%) attributed to adenovirus. Of the 83 rotaviruses identified, 42 were characterized by RT-PCR, of these 40 (95.2%) were proved as type A (VP6), and 2 (4.8%) type C (VP7). Type C (VP7) rotavirus was detected in samples collected from children under 5years only.

Conclusions – In conclusion, most cases of viral diarrhea are found to be caused by rotavirus especially among children less than five years. Most of the identified rotavirus belonged to type A (VP6). It was also evident that most patients are those who drank untreated water obtained from donkey carts source and who had no access to latrines, and lived in poor environmental conditions would acquire diarrheal infection.

DfID – Water, Sanitation and Hygiene Evidence paper

May 8, 2013 · 0 comments

Water, Sanitation and Hygiene Evidence paper, May 2013. DfID.

This paper was commissioned by the DFID Water and Sanitation and Research and Evidence Division (RED) Teams and undertaken by the DFID-funded Sanitation and Hygiene Applied Research for Equity (SHARE) research programme consortium.

Specifically, and in line with general aims described above, this WASH Evidence Paper aims to:

  • Provide an accessible guide to existing evidence including a conceptual framework for understanding how WASH impacts on health and well-being and a description of methods used for ascertaining the health, economic and social impacts of WASH
  • Present the available evidence on the benefits and cost-effectiveness of interventions on WASH
  • Identify what we do know and also what we do not know, and assess the robustness of the available evidence relating to the impact of WASH interventions.
  • Disaggregate the benefits, where possible, by gender and poverty and the distribution of the global impacts across regions and economic status of countries.

This WASH Evidence Paper does not make specific recommendations on what DFID should or should not do, but instead identifies key lessons for consideration in evidence-based policy-making in the following areas:

1. evidence of impact

2. evidence of what works

3. evidence on cost-effectiveness and value for money

4. remaining knowledge gaps
