From The Global Handwashing Day website:

The driving theme for Global Handwashing Day is children and schools, and the main objectives of this global celebration are:

• Foster and support a global and local culture of handwashing with soap.
  
• Shine a spotlight on the state of handwashing in each country.
  
• Raise awareness about the benefits of handwashing with soap.
