Changes

Changing behaviour is very difficult. Companies are very succesful at changing behaviour, as the very succesful efforts to get soap in almost every household around the world show. Therefore, knowledge sharing between the public sector, the private sector and NGO's can be very beneficial, and Public-Private Partnerships are a good possibility here. This type of cooperation has been the basis of the Global Public-Private Partnership for Handwashing<ref>[http://www.globalhandwashing.org Global Public-Private Partnership for Handwashing website]</ref>.
