Rates of hand-washing around the world are low. Observed rates of handwashing with soap at critical moments – before handling food and after using the toilet – range from zero per cent to 34%. “More than 1.5 million children under five die each year as a result of diarrhoea – it is the second most common cause of child deaths worldwide. Hand-washing with soap can save lives by reducing diarrhoea rates by more than 40%.
Global Handwashing Day was initiated in 2008 by the global Public Private Partnership for hand washing with soap, and it is endorsed by a wide array of governments, international institutions, civil society organisations, NGOs, private companies and individuals around the globe
