Gaby Judah, a Cambridge University graduate on Natural Sciences, is currently working on the pilot of the Hygiene-Wired project which will be measuring the impact of different interventions on hand washing behaviour in public toilets.
The School’s involvement
in a public-private partnership (PPP) aimed at promoting
handwashing in Uganda has been highlighted in the Financial
The School has joined forces with Unilever, USAid, the Bill and Melinda Gates Foundation, and Unicef to form a PPP, coordinated by the World Bank. The Uganda project is one of fifteen projects globally including Kenya, Tanzania, Senegal and Benin, where a total of $4.5 million is set to be spent this financial year.
The article discusses how handwashing,
a ‘do-it-yourself vaccination’, is one of
the most cost effective ways of saving lives and outlines
how the PPP's came about – because of the realisation
by groups with an interest in handwashing – soap
manufacturers, funding bodies, NGO's and research institutions
- that by working more closely together, and pooling
their individual strengths and skills, everybody wins
– attitudes are changed, children’s lives
are saved, and soap sales go up!
It outlines a campaign which Unilever is running, together with the School and other partners, to promote the benefits of handwashing with soap, which can eliminate the bugs that cause diarrhoea and respiratory infections, the two biggest killers of children in Africa after malaria. The campaign includes putting on a show in Muko, Uganda, as a pilot for a government-backed country-wide campaign, in which performers promote handwashing in eleven languages.
Val Curtis, who helped found the PPP initiative said:
“I’m delighted to see soap companies taking up the challenge of promoting handwashing. This could save millions of lives worldwide, and better, because companies can make a profit, their efforts will continue to improve public health long after aid projects have ”

Eileen Chappell attended the launch of the UNEP’s 4th integrated assessment report on the state of the environment. The report, entitled ‘Global Environment Outlook: environment for development’, assesses the current situation over many areas including access to water and sanitation. It discusses the possibility of achieving the MDGs and includes a metadata directory.
Adam Biran has recently returned from China where he has been providing technical assistance to help assess training needs and to help with designing and implementing a baseline survey for the Hygiene Promotion component of the project.
The purpose of the trip was to train a team of 6 fieldworkers to carry out structured observation of hand-washing practices in homes.
The fieldworkers were all women and were mostly recent graduates with some experience of community mobilization work in the hygiene, water and sanitation sector. The fieldworkers grasped the principles of structured observation easily and the supervised observation sessions allowed various minor issues related to the data recording procedure to be uncovered and addressed.
In contrast to recent work in India, the households were much more curious about and suspicious of the study. The use of soap for hand-washing was extremely rare and was only observed in relation to food handling and not latrine use or other faecal contact.
Getting fieldworkers to their allocated houses in time to start data collection was a logistical problem. Fieldworkers had to be escorted to houses in the dark in order to be in position to record the flurry of activity that occurred in some houses as soon as the sun rose. Although it was possible to achieve this for a small study such as this, the problems would be much greater in using structured observation as an evaluation tool for a large intervention.
An article by Jeroen Ensink entitled ‘Simple intervention to reduce mosquito breeding in waste stabilisation ponds’ had been published in ‘Transactions of the Royal Society of Tropical Medicine and Hygiene’ Journal, September 2007
Waste stabilisation ponds (WSP) are the preferred method for treatment of urban wastewater in low-income countries but, especially in arid regions, the pond systems can be important breeding sites for mosquitoes of medical importance. In a WSP system in Faisalabad, Pakistan, we assessed the impact of simple environmental interventions on mosquito occurrence and abundance.
Reducing the amount of floating matter in the ponds, eliminating emergent vegetation and repairing cracks in the cement structure reduced the number of mosquito-positive samples in the intervention ponds to almost zero, whereas the control ponds had a significant number of positive samples. This suggests that a combination of simple low-cost interventions is a feasible environmental management strategy for vector control in WSP systems that are located in areas where medically important mosquitoes may breed in the shallow ponds.
A second article by Dr Ensink entitled ‘Waste stabilization pond performance and wastewater use in agriculture in Pakistan’ has been published in Urban Water journal, December 2007
Robert Aunger and Val Curtis have won a substantial award from the UK's Economic and Social Research Council to conduct research on the design and use of a naturalistic mobile experimental laboratory for testing hygiene interventions.
The World Health Organization has just published a new monograph by Thomas Clasen, head of the Hygiene Centre water group, and Laurence Haller of the WHO entitled "Water Quality Interventions to Prevent Diarrhoea: Cost and Cost Effectiveness".
The CEA follow WHO CHOICE methodology to assess conventional and emerging point-of-use water treatment methods in 11 WHO epidemiological sub regions. It concludes that most such interventions meet internationally-accepted benchmarks for "highly cost effective" interventions. Some of the interventions actually result in net savings to the health sector and individuals when reduced cost for treatment of disease are taken into consideration.
Beth Scott presented a model for understanding household demand for sanitation and participated in a panel discussion in the Sanitation 21 Session at World Water Week in Stockholm.
On Monday 10th September Val Curtis appeared on the BBC 3 programme How dirty can I get? The television presenter had given up washing for 60 days. Val said that she was lucky not to have got ill and was probably protected by the good hygiene of those around her.
The show also featured on an item in Woman's Hour on BBC Radio 4. You can Listen Again for 7 days.
A paper, entitled: "Impact on diarrhoea of a city-wide sanitation programme in Northeast Brazil" by Barreto et al, on which Sandy Cairncross is a co-author has been accepted for publication by the Lancet. It shows that a $440 million dollar sewerage scheme in the City of Salvador (pop. 2.4 million) reduced diarrhoea by more than 20% overall, and by double that in the areas where diarrhoea incidence was initially highest. It is one of very few studies of environmental health impact on the scale of a population of millions, and one of a tiny number on the impact of sanitation alone. Coming just before the launching of 2008 as the International Year of Sanitation, it is well-timed.
Val Curtis will be attending the steering committee meeting of the global Public Private Partnership on handwashing. She will be making a special presentation on the work on China. Val will also be speaking at the University of Handwashing, attended by participants from over 20 countries (13th-14th September) on the results of formative research into handwashing in 12 countries. She will conclude that disgust and social norms are the two most important drivers of handwashing with soap.
Beth Scott will be giving a presentation on Sanitation Demand at World Water Week in Stockholm later this month. A copy of her presentation will be available on this web site after the conference.

Curtis and Bob
Aunger gave technical assistance to the Uganda
National Handwash Programme in reporting on its formative
research, producing what one World Bank official called
the best formative research report he had seen.
The study gave detailed insights into handwashing in Uganda, showing that, though 84% of mothers believed that hands should be washed with soap after the toilet, only 14% were actually doing so.
Soap was available in 95% of households, and a block of the local laundry soap was affordable, costing the same as one cigarette. Nevertheless, rural mothers felt that handwashing with soap was not for people like them, who live in villages and dig for a living, but was more for sophisticated urbanites. This perception provides one of a number of challenges to the designers of the campaign.
The report, which should soon be
available on the PPP handwash website, included the
first analysis of school- versus home-based handwashing
practice by children, and a detailed examination of
handwashing motivations in adults.
