The new UN IYS site has interesting public service announcments and key messages that can be used for the International Year of Sanitation.

Proper sanitation: It’s a seemingly mundane thing that most people in the developed world take for granted. But at least 2.6 billion people – some 41 percent of the global population - do not have access to latrines or any sort of basic sanitation facilities. As a result millions suffer from a wide range of preventable illnesses, such as diarrhoea, which claim thousands of lives each day, primarily young children.

Improving access to sanitation is a good investment because:

Sanitation is vital for human health
Sanitation generates economic benefits
Sanitation contributes to dignity and social development
Sanitation helps the environment
Improving sanitation is achievable!
