Scientists have long established that washing hands with soap makes a a crucial positive impact on health and hygiene (see WELL factsheet). But how to get soap used in very poor communities who are unaccustomed and perhaps cannot afford it?
For a quick read, see the brochure Handwashing with soap: why it works and how to do it from the London School of Hygiene & Tropical Medicine. With pictures! This emphasises the need for behaviour change and how it could be achieved.
Here is a brilliant poster of the ‘F-diagram’ from the Loughborough University Water, Engineering and Development Centre (WEDC).
For a more strategic view, there is The Handwashing Handbook – a detailed guide for developing a hygiene promotion program to increase hand washing with soap aimed at a national level. (As an aside, this reads like it was written by business analysts and could serve as a case study in many kinds of development initiatives.)
An alternative to donated aid is the micro-franchise model of distribution which can go beyond just soap to include a broader range of healthcare products – see Healthy Entrepreneurs Foundation as an example.
The charity Global Soap Project and the associated Clean The World Foundation work together to recycle unused soap from hotels and distribute them via NGOs. I love Global Soap’s infographic of their business operation “on one sheet of paper”.
Now wash your hands!
